DIY tomahawk alarm unit repair

Symptoms: the right or left side of the turn signals "burns" constantly sticks.

Reasons for the malfunction: turn signal relay in the passenger compartment or turn signal relay in the alarm unit.

As expected, at the very beginning, start from the simplest to the most difficult - it was decided to change the relay in the car - here is the link. Unfortunately, the replacement did not help to eliminate the malfunction and the right side of the turn signals continued to stick to "burn".

As a result, it became clear that the cause of the malfunction lies in the tomahawk 9010 alarm unit itself, namely one of the relays. Sticking of turn signals on the right side was accompanied by locking the doors or starting the engine directly from the remote control.

Most often, the unit is located behind the dashboard, it is easy to determine its location, in complete silence, press the key fob and listen to where the clicks of the reels are heard. First of all, we must remove the dashboard, on the cefiro a33 this is done simply, under the steering column there are 3 bolts that need to be unscrewed, then pull the dark frame held by the latches and unscrew 3 bolts from the dashboard itself.

Next, we take out the block itself, it is hard to see in the photo and carefully remove the plastic box.

The moment has come to disconnect the wires from the unit, this must be done very carefully using an awl, tweezers, etc. You can't rush, the wires are thin and there is a high probability of breaking something off.

Pay attention to the left side of the wires, they are very thin, be careful again.

Important! If it is possible not to unsolder the relay, then use it! I have a special machine with fine cutting attachments, I carefully walked over the entire top of the relay and opened it. After the autopsy, it became clear where you can cut and where you can not.

He carefully removed the plastic that interferes with getting to the contacts - you can see them in the photo. They were burnt. I took a thin sandpaper, cut out the thin strips and slowly began to clean their inner part - the one that is in contact with both contacts.

Try not to bend the contacts, otherwise, after assembly, it will be found that one of the sides will not work at all and you will have to disassemble and bend them into alignment again.

After cleaning, I assembled everything in the reverse order and checked, the malfunction was, however, eliminated. Everything took about 2-3 hours of leisurely work.

A car alarm, like any other component of a vehicle, can sometimes fail. What if the car alarm does not work in your car, what could be the reasons, what are the most common malfunctions and how to solve them? You will find answers to these and other questions below.

If the car alarm stops working when the remote control buttons are turned on, then the safety of the vehicle can be called into question. Before removing and checking the causes of the malfunction of the alarm and changing the device, we suggest that you familiarize yourself with important information. For example, if alarm malfunctions are in no way related to the operating system, then it is quite possible to solve the problem with your own hands. If you do not want to pay money for car alarm diagnostics, then first of all, familiarize yourself with the main breakdowns of the anti-theft system.

If you decide to remove and check the device with your own hands, then in some cases it will indeed be possible to make repairs yourself. If the immobilizer is buggy and you want to know why, then remember that you should always have the basic tools at hand.We are talking about screwdrivers, pliers, electrical tape, a set of wires in the event of an open circuit, as well as a tester, which are used to dial the wiring. Of course, if your car's car alarm is still under warranty, it is better not to go into it with your own hands, but entrust this matter to specialists (video author - Andrey Kanaev).

What to do if the car alarm blocks the engine and you can't unlock it with your own hands? Why does the device junk and not work as it should? What if the system closes but does not open the doors?

First of all, you need to understand the reasons:

As you already understood, in fact, there are a lot of factors that affect the inoperability of the device, because electronics is a delicate matter and requires the right approach. But if the engine does not start due to blockage, this is not a reason to panic and replace the alarm as a whole. Sometimes the problem will be solved only by repairing the immobilizer. There is a possibility that after a routine test of the system, the car alarm will not need to be replaced.

Anti-theft control panel disassembly procedure

If the engine starts, but when you press the arming buttons of the remote control, the function does not work, then there may be several options for solving the problem:

1. First of all, try to bring the remote control closer to the car, in particular, to the place where the central unit or antenna with LED is installed. Try to arm the device again.
2. If this does not help, then you can try to reset the signaling by disconnecting and connecting the battery terminal.

As practice shows, such a malfunction can occur most often due to a breakdown of the battery in the remote control, replacing the element will help solve the problem. In some cases, a malfunction occurs when the car is parked next to any industrial facility around which there is an electromagnetic field. In this case, the pulses that the remote control sends are simply clogged.

Sometimes it happens that while driving, the car simply stalled, or you turned off the ignition, and when you try to turn it on, the siren starts working. In this case, the engine, as you understand, will not start. There is a possibility that the charge from the battery has disappeared, the battery is completely discharged. In this case, the engine, of course, will not start. The anti-theft system responded when the voltage level dropped below 8 volts. Usually, manufacturers themselves install such a function so that in the event of a break-in of a car and a disconnection of the battery terminal, the siren should work. The only way out in this case will be to turn off the siren of the anti-theft system and solve problems related to battery performance.

Microcircuit of the central block of car alarm

There is one more problem that is relevant for some domestic cars. For example, on VAZ cars, the alarm unit is sometimes installed under the steering wheel on the left, in the area of ​​the hood opening handle. If the place through which the cable to open the hood passes through moisture, which happens when the sealing gasket loses its tightness, this may affect the operation of the unit. Since water gets on the bonnet cable anyway when it rains, droplets of liquid can travel along it when the driver tries to open the engine compartment.

Once in the passenger compartment, drops of water drip onto the signaling unit (if it is installed directly under the hood opening handle), as a result of which they can cause the unit to close. The central unit of the system will simply freeze, block the engine and it will be impossible to start it. The only way out is to completely dry the block, in this case you can only hope that after drying it will start working again. But usually the problem is solved by replacing the microcircuit in the block or the block itself.

So, we examined the causes and main ways of solving problems with a non-working alarm.When problems arise with the anti-theft system, it is important not to panic, but to try to diagnose it on your own. Remember that if the system is under warranty, then in no case should you open it yourself, and even more so make repairs yourself.

Informative information on repairing an alarm unit microcircuit at home is presented in the video below (the author of the video is peling dot).

During the operation of the car, it becomes necessary to repair its systems and assemblies. The security system in this regard is no exception. To save money, you can do it yourself. In this article, you will learn how to repair car alarms and key fob with your own hands.

All alarm faults can be conditionally divided into the following types:

• nutritional problems;
• wiring problems;
• software failure;
• false positives;
• malfunction in the key fob.

Let's take a closer look at each of the malfunctions in car alarms.

Power problems are often the cause of alarms not working properly. This can happen both with the equipment installed on the car and with the car alarm key fob. The system is de-energized due to a discharged vehicle battery. The car stops responding to the owner's commands. The battery, which serves as a power source for the key fob, can also be discharged. In this case, the lamp and display of the device will turn off. A decrease in the battery charge can be noticed in a timely manner by decreasing the range of the key fob.

Defects in the wiring sometimes become the cause of the system being de-energized. Over time, the contacts oxidize, which leads to the interruption of the transmission of electricity. The wires themselves may also be damaged. This happens during the installation of additional equipment or when attempting to steal the machine. Another reason is faulty fuses. The symptoms are the same as with power problems - the car does not respond to commands. This is provided that the key fob is in working order.

Sometimes car alarm malfunctions are caused by incorrect operation of the control unit - the "brain" of the system. This is due to a software failure.

These malfunctions are caused by errors in the setup or installation of the car alarm. If the sensitivity of the sensors is set too high, then the alarm will be triggered at the slightest shock or vibration. Alarms can be caused by small dry tree branches falling onto the machine, rain, or even a loud sound. Sensors set for optimal sensitivity, but installed on plastic parts, will also not work correctly. The fact is that plastic amplifies the vibrations that the sensors perceive. When heated, this material expands, which can trigger the sensors.

During operation, the key fob may start to work incorrectly or even break down. The reasons for this are wear and various damage caused by falling or exposure to water. A cracked display significantly reduces the information content and usability of the security complex. Dropping the key chain can also damage the quartz.

Before starting to repair car alarms, you need to find the cause of the malfunction. Completely different breakdowns can have the same symptoms. To accurately determine the cause of the malfunction, it is necessary to consider all possible options in stages.

You need to start with the key fob. Inspect it for mechanical damage and traces of water. If the key fob gets into water, condensation will form on the inside of the display lid. The operation of such a device (if it turns on) will be unstable. If the key fob did not fall and fell into the water, but the display is turned off and nothing happens when you press the buttons, then the discharged battery is to blame.

If the key fob is completely functional, but nothing happens when you press its buttons, then there may be two reasons for this - strong external interference or problems with the car and the alarm. Try to bring the key fob to the part of the car where the car alarm antenna is installed and press the button. If nothing happens, then the malfunctions need to be looked for in the car itself or in the alarm equipment installed on it.

Next, power and wiring diagnostics are performed. Check the battery charge and inspect the terminals for oxidation. The full charge of the battery can be easily determined by the operation of the on-board electronics. If everything is in order, then the next step is to check the wiring. To do this, you need a special tester with which the contacts are called. Inspect the wires for mechanical damage. Special attention should be paid to fuses. Usually they are in a box, which is located on the wire coming from the positive terminal of the battery.

If the cause has not yet been found, then a defect in the control unit or a failure of its software is to blame. It will not be possible to eliminate such a defect with your own hands, but with a software failure, everything is much easier - it is enough to carry out simple manipulations, which we will talk about below.

Most often, a car alarm key fob requires repair. The buttons wear out and begin to react poorly to pressing, and the device itself may fall on the asphalt or into a puddle. Button repair includes disassembling the case, cleaning the contacts and replacing the button pads (if necessary). To raise the recessed buttons, you can make a plastic backing that sticks to their seats on the board.

Most often, when the key fob falls from its board, quartz comes off. To eliminate this defect, it is enough to disassemble the keychain and solder the quartz to its original place.

To fix cracks in the display, you need to completely replace it. Remove the old display, strip the contacts and solder the cables of the new display. The process itself is not very complex and requires initial soldering skills. The difficulty lies in finding a new display. You can hardly find it in stores, so you will have to order from China via the Internet. Defects caused by water ingress cannot be eliminated by yourself.

Power and wiring problems are solved by stripping the battery contacts and terminals, and replacing fuses and damaged wires. To avoid unnecessary work, use the tester to find the exact cause of the problem and then fix it.

To eliminate the problem of false alarms, it is necessary to adjust the sensitivity of the sensors. The adjustment process is extremely simple. To do this, screw in or unscrew the adjusting screw located on the sensor housing.

To resolve software crashes, you need to reboot the system. To do this, de-energize it by disconnecting one of the terminals from the battery for a few minutes. If this does not help, then set the factory settings of the car alarm. Step-by-step instructions for resetting the settings can be found in the instructions for your alarm model.

The best way to test your car alarm is to use it as directed. Arming the car and try to open doors, trunk or hit the car. You should hit the wheels, hood and windows, gradually increasing the force of the impact. After checking the sensitivity setting of the sensors, open the car door with the key and try to start it, also using the key. The alarm should go off. Check the rest of the functionality, depending on the specific model, the functionality will be very different, we suggested how to check the basic and general alarm functions.

Most of the problems associated with the operation of car alarms can be eliminated by hand. It is better to entrust the repair of the control unit and other complex electronics to specialists.If, after following the above recommendations, the breakdown is not eliminated, then you need to contact a car service. To continue driving with a broken alarm, you need to master the process of turning it off with a secret button, which you can read about in the instructions for the car alarm.

A reliable alarm is a guarantee of the safety of the car.

A modern security system should include a large number of functions that provide comprehensive control over the condition of the car.

The issue of protecting a vehicle from theft is an issue that is relevant for every car owner.

Car alarms are one of the options for those who care about protection. The Tomahawk 9010 trademark has become one of the most demanded in the modern market.

Alarm Tomahawk 9010 has properties that are inherent only in this brand.

• There is an additional function of feedback with the car owner. She is usually supplied with all modern models.
• Signal eavesdropping protection is constantly being strengthened.
• The alarm allows you to start, warm up the engine remotely.

The instructions for 9010 are needed to familiarize themselves with all the properties that a particular device has, and the buyer had the following information:

1. Schemes according to which the security system is connected.
2. Basic principles of system installation.
3. By functional features.
4. About the complete set.

Many car enthusiasts are faced with a situation where the 9010 key fob does not respond to any movement. Such situations develop for several reasons.

• The need to reprogram the key fob.
• Being in the area of ​​radio interference.
• The battery has run out of energy.

It is recommended to contact the installers if the fuel pump does not turn on when the 9010 alarm is active. They will check the signal quality, the connections are already in place. The central locking drive requires an additional check if the doors do not close, do not respond to buttons.

The battery is checked when the key fob starts to fail. If it does not help, there is a need for reprogramming.

Finally, the faults are clearly related to the Comms module loop when the alarm flashes 10 times.

To configure the Tomahawk 9010, it is usually enough to press a combination of buttons on the key fob, or one of them. It is important here to follow the instructions issued by the manufacturer. In order for the system to work correctly, it is required to adjust the sensors, which are responsible for a timely response to outside interference.

Sometimes alarms do not work due to the fact that the sensors are not fixed at the proper level of quality. This is also due to the underestimated sensitivity. The work associated with increasing the sensitivity consists of several stages.

• First, they find a sensor already installed in the cabin. Most often it is located under the front panel.
• The alarm must be removed from the security mode. Only then is access to programming available.
• The sensitivity scale has only a few levels, from 0 to 10. When there are only factory settings, the indicator is at the fourth or fifth level.
• The degree of perception by the sensor should be increased, but not immediately. Checks are required on how and at what levels the sensors are operating.

As for the process of resetting the alarm software itself, it is performed as follows. The ignition must be turned off. Then they press the button nine times, which has the inscription Override. The next step is to turn on the ignition. And again we press the same button, but only once.

The next button we need is the one with the lock. Finally, the ignition is turned off completely. Parking lights will flash five times if done correctly.

It is possible to reset the settings to the original parameters associated with the remote start function. For this, the same procedures are carried out. But the Override button is not pressed nine times, but ten times. Parking lights flash six times. This means that the reset is complete.

A separate procedure exists to enable the autostart function in the 9010. The transmission handle is moved to neutral. Then they move on to tightening the "parking brake". And they press the button with the corresponding purpose on the key fob. The key is pulled out of the ignition lock as soon as the characteristic signal sounds. For the next thirty seconds, you need to close the doors, leave the salon.

It is worth paying attention to the functions that the car alarm performs before making the final choice. This will help you understand what features will be encountered during operation.

The Tomahawk series system has the following set of advantages that simultaneously become functions.

1. There is a built-in clock with a timer, an alarm clock.
2. A special operating mode is available to the driver, which offers significant energy savings. In this situation, the car alarm does not work at full capacity.
3. Automatic protection of doors and trunks with a hood.
4. Even when the engine is on, the system performs a self-diagnosis of the machine. She will quickly point out faults if any.
5. The Tomahawk system will help you control the temperature inside the cabin with maximum accuracy. After all, there is an additional sensor inside. It is enough just to indicate the temperature range.
6. Tomahawk is an alarm that is compatible with cars of almost any brand. Even the gearbox installed on the transport device does not matter. It doesn't matter what engine the car is running on.
7. The remote control is suitable for automatic shutdown, engine start.
8. The same remote control is used to turn off the siren itself. It is easy to attach to a key ring, aided by its diminutive size.
9. The work continues around the clock.

Installation is easy, even if the person has no experience with the job. Malfunctions appear only after some time.

The main thing that is required is the installation of the electronic unit. It is through him that the device is controlled, and he is in the cabin. It is recommended to set the antenna going to the system unit as high as possible. Then all signals from the remote control will be received without interruption.

Contacts for antenna 9010 with wiring, metal objects are not allowed. Otherwise, the efficiency of the structure is reduced. As for the siren itself, the best place to mount it is in the engine compartment. Then outsiders will have minimal access to the part. Only stand-alone varieties are installed in the well of the service key. Installation is carried out only with the horn down.

In such conditions, moisture will definitely not get inside. The main thing is to properly organize the connection of wires inside the passenger compartment in order to prevent excessive oxidation.

The dashboard is only reassembled after the owner has completed a full customization of the 9010. An important step is the soldering of the wires at the moment when the central locking is connected. The joints are attached to each other using ordinary electrical tape, it copes well with its functions.

It is enough to find the required connectors, following the manufacturer's instructions. The instructions provide detailed color schemes for electrical equipment, but if necessary, information can be easily found on the Internet. As well as ways to restore factory settings.

The shock sensor is securely fixed with ties and tape, it also increases the functionality of the system. The same goes for LED indicators. Their place is where the A-pillar and center panel are.

Sometimes malfunctions appear in the Tomahawk security system, in connection with which it becomes necessary to reprogram the complex. The process of resetting the Tomahawk 9010 to factory settings is described in the car alarm operating manual.

Errors may occur in the Tomahawk 9010 system that prevent it from being used in normal mode.

Causes of this system include:

• a failed battery;
• finding the car in the radio interference zone;
• lack of conditions for wave transmission;
• wear and tear of the security system itself;
• violation of the synchronization of the car with the remote control.

The video shows a brief overview of the 9010. Provided by Alexey Viselovsky channel.

This is the most common and easily fixable problem. Perhaps the battery is discharged, which can be guessed in advance by the dimmed screen of the remote control. Also, the reason may be an incorrectly installed battery.

The manufacturer recommends using AAA alkaline batteries to replace the battery in the Tomahawk 9010 keychain.

To resolve the issue, the user needs to remove and reinstall the battery. If this does not fix the problem, then replace it with a new one.

Correct battery replacement in Tomahawk 9010:

1. Open the keychain cover.
2. Remove the old battery.
3. Press the trunk open button.
4. Insert a new battery.
5. Close the key fob cover.
6. Press the trunk open button.

Staying near cash-in-transit vehicles or near airports and shopping centers may cause radio interference, a parameter that prevents the Tomahawk system from working properly.

In this case, try a few things:

• bring the key fob as close as possible to the place of the security system sensor;
• click the Override button;
• evacuate the car from the radio interference zone at a distance of 200 meters.

During severe frosts, the voltage on the car's battery may not be enough to make the auto start or unlock the doors. In this situation, only solving the problem with a faulty battery will help, it must be charged.

It is also possible damage to the keychain itself, which occurs due to frequent involuntary pressing, in which case it will need to be repaired.

Over time, the security system wears out - mechanical breakdowns of the receiving antenna of the transmitter appear, as well as wear of the key fob or unit itself. Unfortunately, in this case, the problem can be eliminated only by replacing or repairing the devices at the service center. It is not recommended to carry out such repair work on your own.

If you have a spare key fob, connect it to the system:

1. Switch on the ignition without starting the engine.
2. Hold down the combination of buttons "trunk opening", "silent protection" and "override". The system will beep 5 times.
3. Release the pressed buttons.
4. Press the "trunk opening" and "silent protection" buttons again. The turn lights will flash several times. The system will automatically program a new key fob.

In a situation where the key fob has lost contact with the car and the alarm control has become impossible, you will have to open the car with a key and use the emergency shutdown function.

Emergency shutdown sequence:

1. Open the car with the key.
2. Start the ignition.
3. Press the Override button 4 times.
4. Switch off ignition.

These actions will be followed by two beeps and double flashing of the vehicle lights, indicating that the alarm has been deactivated. If this method does not help, then the system is faulty. It is necessary to contact the service center in order to repair the signaling or adjust the settings.

In order to reset the Tomahawk 9010 system settings to the factory settings, according to the operation manual, it is recommended to do the following:

1. Switch on the ignition.
2. Press the Override button 10 times.
3. Switch off ignition (confirmation - 10 siren sounds).
4. Press the Override button 1 time (confirmation - 1 siren sound).
5. Press the button with the locks on the keychain.
6. Switch on the ignition. The side lights will flash 5 times. All manipulations should be carried out without delay.

The video from Yakov Toporkov tells how to turn off the alarm if the key fob is faulty.

tracks just don't fade. The tracks, as I understand it, are burned out that go from the relyushki in the whitefish block to the pin 6 connector on the yellow IGN1 wire, it is responsible for the ignition. Now I have a question for the author! Is the ignition lock unloaded on the Nexia? that is, what turns on the ignition, the contacts of the lock or contacts turn on the relays, and the relays already have the ignition and the rest of the consumption. if the latter, then the tracks could not be burned because only the current that the relay consumes about 200 ma would flow along the tracks. If the first option, then the tracks can be burned if there are short circuits in the car's wiring or a source of strong current consumption, the ignition lock can withstand them for a while, but the tracks are thin!

I think it was either crooked, or there was an incident in the wiring of the car, or it was loaded with consumers.
Here is the standard wiring diagram

I have after sh1 on wires 151, and 152 go further relays which carry the main load of all wiring, which appears when the ignition is turned on. Therefore, the relays that are in the alarm unit and the lock contacts include only the relay responsible for the ignition and do not carry any power load in this case, the tracks in the whitefish cannot burn out. If the tracks are burned not by the ones that go from the relay but to the power supply of the relay, that is, the relay in the block does not work during the staging procedure, then there is a marriage in the block itself!

Unfortunately (for car enthusiasts), fortunately (for entrepreneurs), services that have a column in the list of services: repair of car alarm key fobs are flourishing, and all because they have enough customers. The installation of a security system designed to protect against theft of a vehicle, it would seem, should solve all the problems of the car owner, but no one is insured against breakdowns. And, as a rule, the most vulnerable element of the system breaks down, namely: the alarm key fob.

If the car alarm stops responding to commands from the control panel (key fob), then first you need to understand what is the reason for this development of events and only then decide what to do in this case?

There are enough reasons to either contact a company that repairs alarm key fobs, or spend time studying this issue in order to further self-repair the key fob. For a list of the most common keyfob malfunctions and their causes:

1. The buttons do not respond. The problem may be due to:
   • sticky buttons;
   • failure of the button itself, contact or wire as a result of natural wear and tear or mechanical impact (shock);
   • the absence of a sufficiently strong fastening of one of the elements of the main board (the contacts have moved away).
   • Weak backlighting. The indicator LED is dim and the screen is dark. A malfunction can be triggered by:
     • insufficient charge of the power source (battery);
     • failure of the controller;
     • the departure of quartz from the processor;
     • violation of the integrity of the fastening of the contacts (often observed after the fall of the car alarm key fob).
     • There is no feedback. The system does not respond to commands sent from the remote control. Possible causes of the malfunction:
       • decoupling the keychain (violation of synchronization between the remote control and the elements installed on the car);
       • wear (breakage, damage) of the transmitter reception antenna;
       • the installation of the alarm was performed incorrectly (errors either during installation or during connection).

There are other reasons forcing the motorist to use the service: repair the alarm key fob or try to return this important element of the security system to its original characteristics with his own hands.

If the key fob is broken, it is not at all necessary to immediately buy a new control panel. In most cases, a faulty key fob can be reanimated. Some breakdowns can be repaired by yourself. In this case, you need to act in stages:

1. Step one (diagnostics). First, you need to identify where the failure occurred (disassemble the key fob into its component parts, ring the board contacts, the tester will point out problem areas, check the condition of the battery, carefully inspect every detail for damage or wear).
2. Step two (assessment of opportunities). Based on the results obtained, decide how to proceed (contact the professionals or still repair the keychain with your own hands).
   The list of tasks that you can cope with on your own (if you have basic knowledge that does not imply special training) includes the following items:

• replacement of parts (a car enthusiast can himself replace such elements of the keychain device as: case, display, button, but there is one "but": finding spare parts for some alarm models is quite problematic);
• soldering contacts (gluing quartz with thermal paste);
• reprogramming the control panel (detailed information on how to bind the key fob to the alarm, including the one already recorded in the system memory, can be found in the operating instructions).

Step three. Direct troubleshooting, performance check.

If it was not possible to repair the keychain using your own skills and abilities, it makes sense to seek help from specialists. At the same time, neither the brand of the alarm system (Starline, Sherkhan, Pandora, Tomahawk, Pharaoh and others), nor the type of security system (GSM, GPS alarm), nor its class (economy, business, premium) matters. Highly qualified craftsmen are able to restore the functionality of any alarm key fob (if possible and justified).

The list of works available to clients of such a service includes such actions as:

• diagnostics of the technical condition of keyfobs (carried out using modern equipment that allows you to get accurate results within just a couple of minutes);
• replacement of parts (display glass, display itself, faulty button, damaged case, metal or plastic antenna, battery cover);
• restoration of the microcircuit (elimination of breaks in the circuit of the main board);
• car alarm key fob coding (reprogramming - in case of successful repair of the old one, binding of a new one - in case of an unsuccessful attempt to repair or its recognition by the masters as inexpedient).

What are the advantages of a professional renovation? In 100% quality of the work performed, confirmed by warranty obligations and in a short time to solve the problem.

What is the disadvantage? The need to part with your own finances.

Summing up, I would like to say: in most cases, a car alarm key fob can be repaired. Breakage is not a sentence yet!
