REPAIR AND REPROGRAMMING OF UNITS (CONTROLLERS) VOLVO

I am engaged in the repair and programming of car modules VOLVO 30/40/50/60/70/80/90 models.

You don't need a machine to program used modules, I do all the operations on my stands, which is very convenient for people from other cities.

Sending blocks by express mail, 2-3 days and the block is already with you.

CHOOSE THE MODULE OF INTEREST FROM THE MENU

If your dashboard stops working on your car, information is not displayed on the displays, dial gauges do not work, it can be repaired.

About the repair of the device and the manifestation of its defect.

The defect manifests itself in different ways. The first stage is usually crumbled letters, slashed text in the route book window. Further, the defect progresses and the backlight starts to go out, then the turn signal indication turns off, then the instrument arrows fall. The blocking of the machine can manifest itself at any time.

It will stop opening from the remote control, since the CAN bus is in transit through the dashboard. Having removed the tidy, do not close the car with the central lock, and do not put on the alarm.

The tidy, failing to operate, instead of the correct information, begins to issue to the CAN bus the devil knows what data, as a result, the exchange of data with other units is blocked. It is enough that it will generate a code for blocking data exchange on the CAN bus. As a result, the car “falls asleep”. On the go, this is expressed in the form of kicks, fuel cutoffs.

Wishing to figure it out on their own , if you know how to read schematic diagrams, you will understand me. They are all posted on the forum.

In custody .

Repair, for me, of the dashboard costs from 5,000 to 1,500 rubles, with a ONE YEAR guarantee (such a guarantee is given on all units that I repair). If someone dig deeper into the tidy and after that they brought it to me, the repair will cost 25,000 rubles without any guarantees and no matter what is wrong there.

DIM repair takes AT LEAST 2 hours. This is the time of a clean repair, it does not take into account the time taken to diagnose the car before and after the repair by dealer VIDA + DICE equipment. Sometimes complex defects took several days.

The repair is carried out not on the knee in the car, but using stands and equipment necessary for carrying out repairs in a comfortable environment. This allows us to guarantee the carried out repairs with 100% certainty.

Write to me in this vein: - “Tell me how. , show what. soldering, I myself can poke with a soldering iron. ”. I do not intend to study an educational program on this topic. They will always remain unanswered, for any block, it does not matter if it is a tidy or some other block.

Therefore, you should not waste time on such letters.

If an error appears BRAKE ASSIST SERVICE REQUIRED on the dashboard, mileage is no longer counted, cruise control does not work. Diagnostics indicate loss of communication with the BCM. The official dealership service center announces that the BCM needs to be replaced, it can be repaired.

Contact us, the repair takes at least 1 day, since after the repair the unit needs to be sealed, the sealant cured for at least 12 hours, the car does not need to be left.

The window regulator control panel stopped working, the central locking does not work, the rear-view mirror control does not work. The overboard temperature is not shown on the display. The defect often appears in winter. The block starts to pop with a built-in relay. Module repair will be required.

There is a malfunction in the module, there is no communication with the module.

First of all, check the fuse in the REM (rear electronic module) installed in the trunk of the car on the left side, under the trim. If the fuse is blown, this indicates the wear of the oil pump, or rather its motor. It will be necessary to replace the oil filter and repair or replace the pump motor. Only then can the DEM be repaired (which, however, may not be needed at all). Having done all this, you can contact me for repairs. Otherwise, you will hear it all from me again. It is pointless to make repairs without replacing the fuse, pump motor and filter, since the module will burn out again. I will not undertake such repairs, since I give a one year guarantee for the repairs carried out.

For repair, I need an already dismantled module.

Common causes of module failure are not only pump malfunction, but also holes in the housing cover. Treat the module in advance with an anti-corrosion coating ... Preferably with a thick layer of plastisol or similar Valvolin anticorrosives. In the photo you will see how it looks from the inside.

To protect against theft of the module, which has become more frequent in Moscow, replace one of the mounting bolts with a shear bolt, or drill the TO RX head with a drill, so that there are no faces left for capturing the head. Thus, you will save from 30,000 to 170,000 rubles. Since in case of theft, they also cut the wiring of the pump motor and the wiring coming out of the body to the module.

After "skillful actions" with the electrical equipment of a car, an error often lights up SRS-AIRBAG SERVICE URGENT. You will need to work with service equipment. If the car has been in an accident and it is not possible with service devices, after restoring all security systems, reset the error, the unit will need to be repaired or reprogrammed.

For repair, I need an already dismantled module.

One of the most common manifestations of a malfunction is the text on the display:

ANTI-SKID SERVICE REQUIRED - ANTI-SKID SERVICE REQUIRED.

The diagnostics will reveal a periodic loss of communication with the module, or an error in the steering angle sensor. The module can be repaired.

For repair, I need a dismantled module, module exchange is possible. I do not dismantle the module, repair or exchange is carried out only through the service, or you do this operation yourself. After replacing or installing a module SAS after repair, it is MANDATORY to do diagnostics and calibration of systems car which includes SAS, BCM, DEM, AYC.

The climate control module stopped working completely. The backlight does not work, and the signal LEDs on the buttons. As well as additional buttons located on it (folding the headrest, folding mirrors, turning off the alarm volume sensor, etc.) The unit will need to be repaired, reprogrammed.

The interior temperature sensor is often broken. He is behind bars (seen in the photo). Replacing the sensor is possible.

If the engine control module is out of order, it can be repaired, or replaced with a similar used module, with its preliminary reprogramming.

Repair of CD, DVD changers on 6 discs used in VOLVO cars.

The defect of the HU-xxx radio tape recorder is manifested in the form:

- loss of sound through channels,

- periodic clicks in the speakers with no sound, even when the radio is turned off.

- not the ability to control the radio from the steering wheel buttons

- disappearance of the backlight of the display of the radio

- failure of the CD6 drive

Reprogramming the DVD module to the 5th region.

repair and reprogramming of used modules to your car

For repair, I need an already dismantled module. A machine without a module will not close. The repair period is 1 day.

There is a separate story about this module:

Do not lose hope, contact me, I will help you in this situation.

The topic I wrote about above at the St. Petersburg Volvo club

repair and reprogramming of used modules to your car

Most often, the reason for the failure of CEM modules of this design is associated with their flooding with water or washing liquid due to a design flaw in the car or clogged drainages of the hatch and windshield well.

The second most frequent failure of this module is associated with the installation of cheap Chinese-made xenon light power supplies on the car. A high-voltage breakdown of the power supply causes failure of the module processor. In this case, it is only possible to replace the block with a donor, followed by reprogramming.

repair and reprogramming of used modules to your car

If your display in this module has gone out, or it is randomly turned on or off, the sound volume is not adjusted, when the ignition is off, the module turns on itself.

A UEM malfunction usually manifests itself like this:

- the remote control (RC) of the alarm does not work well to control the central lock (CZ).

Before checking, replace the battery in the remote control.

- interior lighting plafonds do not light, although the lamps are in good order.

- the automatic dimming of the salon rear-view mirror does not work.

Replacement of a leaking mirror, cracked or broken mirror element is possible.

The dismantled UEM module is required for repair.

CD6 - six CD player for XC90 2003-2006 model year

It fails if you change the battery, or try to start the engine on a dead battery if there is a CD in the drive.

The mechanism fails, in detail with pictures of the malfunction are shown in the article Repair of a CD drive for 6 discs

A dismantled module is required for repair.

If the adapter fails:

- the red LED on the panel blinks or nothing is lit at all

- there is no connection with the car

- there is no communication with one CAN network

- the car does not switch to diagnostic mode

- there is no connection with the computer, DICE is not detected as a device.

It is possible to repair DICE original or Chinese imitations for the original.

Fails when installed instead of standard ORIGINAL lamps, Chinese leftist. Burns well with smoke and stench. In the original, it is not sold separately from the headlight, only the whole headlight. Therefore, think carefully when you are going to save on a light bulb. It all depends on the damage, in some cases repair is possible. If, after repair, you plug in a Chinese fake again, it will burn again. Buy expensive, original lamps, then there will be no problems associated with the repair of blocks.

if the module is not repairable or has mechanical damage, it can be replaced with a used one, or a new one with subsequent reprogramming.

Repair of the ABS Volvo S 70

Repair of the ABS control unit

Volvo behavior in the event of a CEM unit breakdown

Some data about ABS elements

Serrated disc (pulse) 48 teeth

Wheel sensors:
Rated value 300 mV AC at wheel speed 1 ob
The minimum value is 105 mV AC at a speed of rotation of 1 ob
Frequency 48 Hz at a wheel speed of 1 ob
Sensor resistance 1040-1160 Ohm

With our roads and "anti-ice reagents" I advise you to do all this at least once every two years.

Clean wheel speed sensors. Lubricate the connectors with contact grease and remove traces of corrosion in the contact group. The sensor itself and the mounting bolt, when installing back, grease with grease for CV joints or graphite grease. This will make it easier to dismantle them in the future without destruction.

To clean the impulse disk of each wheel, I draw your attention to the fact that an anti-corrosion layer is applied to the surface of the disk. I do not recommend cleaning and scratching it. Therefore, work should be done with a wooden or plastic stick, and a hard, non-metal brush. Pre-soak the surface of the pulse gear with any penetrating liquid (kerosene, WD-40, brake fluid, etc.). All dirt between the teeth must be removed, otherwise the sensor readings may not be correctly interpreted by the ABS unit and it, in turn, will make adjustments to the braking distance. If corrosion has severely damaged the teeth of the impulse disc, then it will have to be replaced.

Trouble-shooting.

Topic: Got rid of the sore.

Earlier I wrote that ABS spontaneously works when braking and turning the steering wheel to the left. I managed to get rid of this sore. It was all about a cracked ABS toothed ring on the grenade. The Svid ring was intact, and at one point they tried to clean it from slags and it fell apart. Replaced, s / h was not cheap, but now everything works.

The original ring cost 1,056 rubles -20% total 849 rubles. in Swed-Mobil with Volvo-850. You can ride, but unpleasant. Good luck.

- in the ATE block, all electronics are produced, ordered from BOSCH, they, in turn, placed an order at a plant in the Philippines.

Well then. Again, and again the quality is nowhere worse. Recently (May 2005) the phenomenon has become widespread. Moreover, even new cars suffer from the same defect, these include 40, 60, 70, 80 series. There is no information about 90 and 50 yet. As for other eminent manufacturers using the same block and its modifications, they encounter the same defect and change the block to a new one. But a new block of the same quality and the same manufacturer, respectively, fails in the same way. But the change of the block at the expense of the client does not suit me personally. Personally, I consider this defect to be a factory defect.

Good day! There is a wonderful device - S60 (2004 2.4-170hp automatic transmission). When I bought, the garland was on fire. When Launch diagnosing the CEM unit, an error occurred when connecting to the ABS unit, so it is impossible to connect to the ABS unit at all. The way out is soldering. Moreover, a couple of times the error itself disappeared and everything started working properly (abs, antibuks, cruise). I have a block 8671222, having opened it today, I did not see soldering, the connector is attached to the board in a different way. I rang the legs to the input resistances on the board - everything is fine. I checked the connector for broken wires, also without crime.

A question for connoisseurs - where to dig next?)) I live in Tyumen, there are no specialists here (at least I haven't found)

Do-it-yourself ABS malfunctions and repairs - you can fix something yourself, without a car service. Almost all modern cars are equipped with an anti-lock braking system. In this case, it is required to carry out the ABS diagnostics regularly. As soon as the ABS and the ESP stabilization system fail while driving, the vehicle's controllability is immediately lost. This can lead to an emergency.

Accordingly, a broken unit should be repaired in time.

Check out - hydraulic pumps produced by Bezares include all the most popular types by the way of connection.

This system has three components: there are wheel sensors, electronic and hydraulic control units. The service station is mainly contacted about a malfunction of the wheel speed sensor, electrical wiring, and the control unit. Only at the station can the malfunction be accurately identified.

The ABS system is considered reliable, it is capable of functioning for a long period. Electronic units are protected from breakage; for this, special relays and fuses are installed.

Mostly wheel sensors break down, they are placed near the rotating components of the hub, the axle shafts. Any contamination, significant backlash in the hub bearings can cause malfunctions in this system.

Do not repair ABS yourself. You can only remove the wheel sensors, install them. The equipment is located in the steering knuckles, as well as on the rear axle shafts.

Do-it-yourself ABS malfunctions and repairs - The procedure for removing, installing sensors is carried out in the following mode:

- disconnect the sensor wire, connect a new one.

DIY ABS malfunctions and repairs

It must be remembered that the functionality of the ABS is influenced by the voltage parameters that are formed between the terminals of the battery. If the voltage drops below 10.5 V, the safety electronic unit shuts down the system. The safety relay will work at the moment of large fluctuations, sharp "surges" of voltage.

The ABS includes several systems - the anti-lock braking system itself, the stability control system and emergency braking. The whole complex is controlled by an electronic control unit, and the final device is the hydraulic system of the vehicle.

Signals for the operation of the ABS systems come from a sensor installed on each of the wheels and monitoring the rotation of the wheel at each moment of movement. Based on the speed of the vehicle, the speed of rotation of the wheel, the condition of the road surface or the angle of inclination of the road, signals for the control valves of hydraulic systems are generated at the output of the electronic unit.

The ABS system is very important for the safe driving of a car, therefore, before undertaking its repair with your own hands, you need to carefully weigh everything. Diagnostics and repair of blocks of the ABS system in a car service, even if it will cost a little more than with your own hands, will guarantee that failures will not occur at the most inopportune time.

This is especially true for those who are accustomed to using the ABS and rely on its performance.

Like most electronic systems, the ABS has primary self-diagnostics that operate when the key is turned. Diagnostics usually takes a few seconds. If after this time no system malfunctions are noticed, the alarm on the dashboard will go out. When the car is moving, the ABS diagnostics works continuously, and when the parameters of the sensors or terminal devices that are not included in the tolerance zone, a malfunction alarm is triggered. When signaling a malfunction, it is necessary with special care to find a convenient place to inspect the car or get to the nearest car service, especially in cold weather, when the roads are slippery. Sometimes it happens that a malfunction can be eliminated with your own hands in a couple of tens of minutes.

To repair blocks of the ABS system with your own hands, you must first measure the voltage of the battery. If the voltage is less than 10.5 V, the ABS control unit will not turn on, so that there are no errors in operation. At normal voltage, you will have to continue troubleshooting. Most of them are due to the wiring of the sensors. Moisture, getting into the connectors, causes oxidation of the contacts, therefore, first of all, you need to assess the condition of the contacts of each sensor of the ABS systems.

Very often, breakdowns of ABS systems are caused by a malfunction of the control unit sensors. To operate the ABS sensor, a gear wheel is attached to the hubs, and the sensor itself is an inductor located at a distance of 0.2–1.5 mm from the teeth. If all the teeth are in place, then it is necessary to measure the gaps between them and the sensors, if necessary, readjust the mounting of the sensors. Dirt accumulated on the teeth and surfaces of the sensors can adversely affect the operation of the ABS.

The coils themselves are checked with an ohmmeter. The device should show a resistance of 1-3 kOhm, depending on the type of sensor. The main thing is that they are all the same on one car. If the ABS sensor coil shows an open or short circuit or is very different from the rest, then it needs to be replaced or repaired.One can only advise to check the place of entry of the connecting conductors into the device. Perhaps the wires are broken, and, having removed a little insulation from the sensor, you can try to solder the break or short. Many devices can be disassembled by heating them with an assembly hair dryer and removing the plastic cover at the wire entry point. It is under this cover that breaks occur most often. In this case, do-it-yourself ABS repairs will not be very serious. Considering the cost of the sensor, such a technique may have a right to exist.

If the sensors are in order, the state of the wiring from them to the electronic unit is not satisfactory, then you need to inspect the control unit. DIY repair of ABS control units is advisable only for those who are very well versed in electronics, know how to use a soldering iron and have the skills to repair electronic devices.The ABS control unit, as a rule, is made non-separable and hermetically sealed with glue. The printed circuit board on it is filled with a special sealant. If you carefully open it, you can look at the wires soldered to the printed circuit board of the block. Very often they do not withstand vibration and come off. The broken wire must be carefully evaporated and another must be soldered instead. For soldering, you need to use an electric soldering iron with a power of no more than 40 watts. Rosin or its solution in ethyl alcohol is used as a flux.Do not use soldering acid for soldering ferrous metals as it will corrode printed tracks and copper wires over time.To check the coils of the hydraulic valves, you need to free their leads from the sealant and apply a voltage of 12 V. A normal coil should work like an electromagnet, attracting steel objects.Coil rewinding and PCB repair should only be performed by a specialist. It is very difficult to do this with your own hands and, moreover, without any guarantee. In any case, after the repair has been completed, the sealant layer must be restored. You can use neutral silicone for this. Regular silicone contains acetic acid. It cannot be used categorically.Some time after the repair, the printed conductors on the control unit board will be completely corroded. For the most part, replacement of the control unit is required.One more note. When replacing brake fluid in a car, it must also be drained from the accumulator (pressure accumulator) of the ABS. This can be done by pressing the brake pedal several times with the ignition off. With the ignition on, the pump in the hydraulic block will try to make up for the loss of fluid. In order to avoid damage to the electronics, during welding on a car, the ABS control unit must also be disconnected from the power circuits by pulling out the connector.Entry posted by Langraf January 18, 2013All the same, I decided to sing this block. I read everything on Volvo850, got a little scared, but then I gathered my strength and started. Although at first a little background.

Then I opened it (breaking off the plastic edge on three sides) (photo # 3) I cleaned everything of silicone. (Photo # 4) I identified problem areas and soldered it. (Photo # 5) (this is exactly where the connector is connected, but just in case the rest details where a large soldering iron was not scary to climb)Collected in reverse order and installed on the car. Errors remained (The lamps turned on and off again. Since the "hand is now full" I removed the block again and soldered again. Just in case, before installing, I removed the terminals from the battery for 10 minutes. I connected and ... the TRACK light stopped shining. As I already knew from my personal experience, the connector is not fully dressed. (although it looks like everything is in order.) As it turned out, during the penultimate dismantling, a piece of this connector broke off and did not allow it to be tightly turned on. I removed it, connected it and now I am a happy owner of a luxurious car, with properly working ABS and a speedometer !The need to repair the ABS Volvo S60 is indicated by an illuminated or flashing light on the instrument panel, the handbrake light may also come on - this means that the ABS has turned off completely. If the vehicle is equipped with an ECU, errors may appear on the computer screen. In this case, you need to go to the service station for diagnostics. ABS is a complex electronic system, without knowledge of the basics of electrical engineering and special measuring instruments, it is impossible to diagnose yourself.ABS Volvo S60 (anti-lock braking system) is designed to prevent unintentional wheel slip during hard braking. It makes intermittent braking by alternating wheel unlocking and locking. This reduces the braking distance of the machine and prevents skidding. It is almost impossible to repair the ABS Volvo S60 on your own.Service station on Grazhdanka - 603-55-05, from 10 to 20, no days off.
Service station in Kupchino - 245-33-15, from 10 to 20, no days off.
STO on Courage, 748-30-20, from 10 to 20, no days off.WhatAapp / Viber: 8-911-766-42-33The main components of this system are the electronic control unit, the hydraulic unit and sensors on the wheels. The electronic control unit fails very rarely, it is equipped with a special protective relay and fuse, its service life is up to 5 years. Since the block body is non-separable, it cannot be repaired, it is replaced. The hydraulic block is located behind the main brake cylinder, here the pump and valves, flexible elements can fail, it is necessary to monitor the state of the working fluid, etc.The most vulnerable part of the ABS in the Volvo S60 is the wheel sensors, which measure the speed of the wheels. They are a coil with a magnetic core that is usually attached to the wheel hub. The most common breakdown is a broken wire from the sensor to the line, clogging of the sensor and the teeth of the wheel, then the data will not go to the control unit. Uneven tire wear or a deflated tube, replaced rubber can interfere with the operation of the ABS sensors. Also, problems may lie in the electrics of the car, a short circuit that has occurred. It is necessary to clean and check all terminals and contacts, check the integrity of the wiring. Our specialized services will help you with this.Without special knowledge and measuring instruments, it is impossible to diagnose and repair the ABS Volvo S60. But our specialists will successfully cope with this.ABS is part of the brake system, it is very important to monitor its serviceability, failure of this unit can provoke an accidentGood day, dear readers! Today we do ABS repair Volvo... FH series car, 2010. First of all, we connect the diagnostics and read the fault codes. Unfortunately, the car does not want to get in touch, we begin to find out the reason. We check the power supply on the chip, +24 is absent. When the ignition is on, an error appears on the SCR system. It turns out that on the eve of the car the emulator failed and the engine speed limitation was activated. We begin to disassemble the left side of the dashboard, take out the OBD2 chip harness. There is also a problem, the emulator is connected to the standard wiring of the car on twists and one of them (apparently the power supply) collapsed. Putting everything back together and soldering it with a soldering iron. Now you can make a diagnosis.ABS logic and ABS sensor are abnormally large changes. We start checking the sensors. To do this, we jack up the rear axle of the car and remove the sensor chips from the modulator.To begin with, we check the resistance of 1 - 150 Ohm, 2 - 145 Ohm, the readings are normal. Now we connect the oscilloscope and we will check the sensors in working order.

Video (click to play).

The oscillogram shows that there is practically no signal. This means that the sensor is either defective itself, or it is far from the ring gear, or the ring gear on the hub is worn out. We begin to remove the wheels. Then we dismantle the caliper, take out the axle shaft and, finally, remove the hub. The crown is normal, the sensor is located correctly. We change the component. We erase errors. We carry out restart No. 2 “Wheel speed”.To do this, we slowly accelerate the car until the speed of the car exceeds 15 km / h. The restart is successful, the lamp on the instrument panel goes out. Work is done. You can get acquainted with the diagnostic service at this link. Another report on the repair of the Volvo brake system is here.
