Car wiring performs one of the most significant roles, as it is actually a connecting link of many functional elements of the car. In the VAZ 2110, the wiring is replaced in the event of a malfunction, or if the owner decided to upgrade. This, in turn, will help to significantly improve the efficiency of the functioning of the electronic systems of the vehicle. Often, old wiring simply cannot withstand the load of various additional high-tech devices. Replacing the wiring in the VAZ 2110 can be easily carried out on your own.
First of all, the car owner must know when and in what cases the car wiring is replaced. At the same time, it is also necessary to have information about the final operational period in order to objectively understand when replacement of the wiring may be necessary. A list of the most common reasons that lead to wiring malfunction:
the appearance of cracks in the insulation during a long operating period;
oxidation;
corrosion;
blown fuse, etc.
Components that are required to perform a wiring replacement:
multivariate set of wires;
fuse block for vaz 21104;
housing for the heating system;
various types of sensors: brake fluid, cooling systems, etc.;
pads;
many terminals;
of course, needless to say, duct tape.
Replacing the wiring on the VAZ 2110
So, a detailed step-by-step algorithm for replacing the wiring:
first, it is necessary to dismantle the front of the passenger compartment;
then you can engage in the proper degree of isolation, if there is a desire;
after which, you need to pay special attention to the headlight switch of the front group;
the wiper (see Replacing the VAZ 2110 windshield wipers on your own) operates at the expense of its own mini-motor, the wiring of which must be checked for serviceability, since very often it simply acidifies;
deal with all heating modes;
the connection of all electronic devices must be carried out strictly sequentially, by increasing the number of connected wires.
Note. Before you carry out the disconnection of all electronic devices, it is necessary to draw a conditional own wiring diagram by hand in order to correctly make the corresponding connections in the future.
now it's time to get busy with fuse boxes, or rather installing them;
most of the wires exceed the required length, so they simply do not fit into the allotted space;
the bracket is the most rational solution to the problem, it will allow you to successfully replace the fuses with new ones;
with the installation of a new fuse, the position of the front light indicator lamp, as well as the emergency one, will change;
the heater will also have to be touched: first you need to remove the old radiator, and then disassemble it so that you have the opportunity to replace the fan;
assembly is carried out strictly in reverse order.
Note. Before proceeding directly with the procedure for replacing the wiring, you need to find its current diagram. Otherwise, during the assembly and disassembly process, you can quickly get confused, and you will have to send the car to a car service.
Wiring diagram for VAZ 2110
The main advantages of the new wiring:
the emergence of a practical opportunity to connect any gadget;
longer service life compared to old wiring;
a high degree of reliability of daily functioning;
improving the quality and stability of electronic devices and much more.
Replacing the wiring VAZ 2110
It is always necessary to remember that the installation of homemade wiring is an easily feasible technical manipulation, the main thing is to understand all the necessary nuances.
the car engine will not start;
Note. If the essence of the malfunction lies in the ignition system, then one of the diagnostic signs is that the car will not start. Moreover, if the car starts up badly, but still starts, then wiring problems can be excluded from the list of possible causes.
the central ignition lock has ceased to function properly;
the car electronics began to function intermittently or does not work at all;
headlights function intermittently or do not function at all;
the characteristic smell of burnt rubber began to appear regularly in the car interior;
the battery discharges too quickly, although it functioned well before;
Replacing the wiring on the VAZ 2110
A practical example of a wiring fault:
the engine began to function unexpectedly with noticeable interruptions;
at first glance, it may seem that the essence of the problem lies in a malfunction of the ignition system;
however, a motorist with sufficient experience will not be able to immediately determine where the essence of the malfunction lies, since the cause of the engine interruption may be the ignition system, or maybe a burned out spark plug, as a result of a wiring malfunction.
Do-it-yourself wiring replacement instructions are extremely simple, and the diagnostic process, in principle, does not present significant practical difficulties. It is recommended to use photo and video materials during the replacement process. The main thing is to find the root cause of the problem in the wiring system. It is never too late to modernize the VAZ wiring, and this, in turn, will allow the use of almost any modern high-tech devices for a car. The price of self-replacement of the wiring is significantly lower than the corresponding service in a car service.
A wiring diagram is used to combine all electrical appliances and equipment in a vehicle. If any of its elements fails, this may affect the functioning of the car as a whole. More similarly, you can learn from this material what the VAZ 2111 wiring diagram is for an 8-valve injector and what malfunctions are typical for it.
What is included in the wiring diagram?
First, we propose to figure out which systems and assemblies are used in the wiring diagram.
Battery. This device is designed to ensure normal engine start and power supply to electrical appliances and equipment when the engine is not running. If the battery is discharged, it will not work to start the engine with the key; you will need to either try to start from the "pusher" or "light up".
Starter. The purpose of this unit is to provide the ignition system with a high-voltage pulse required to ignite the combustible mixture in the internal combustion engine cylinders.
The generator is one of the essential components of any electrical system. This node is necessary to power the electrical devices and devices of the vehicle while it is moving. In addition, the generator allows you to charge the battery, replenishing its charge, which was used to start the engine.
Ignition switch.
Mounting block with fuses. The purpose of fuses cannot be underestimated - these devices are used to ensure the protection of car electrical circuits. If voltage surges occur in the electrical system of the engine of the 16 valve injector, then it is the fuse that will fail first, thus protecting the equipment from damage (the author of the video is the Autoelectrician HF channel).
But these are only the main components of the system, as for the complete wiring diagram, it includes various nodes and systems:
connecting the starter unit;
contactless ignition system;
ignition switch connection diagram;
lighting system, which includes the optics of low and high beam, brake lights, side lights, fog lights, turn signals, as well as lighting in the car interior;
wipers activation system, as well as a windshield and rear window washer;
sound signal activation circuit;
power window activation system;
activation of the ventilation device of the cooling system;
luggage compartment lock;
rear window heating unit;
the instrument panel, which displays all the main instruments of the car, the status of the sensors, the speedometer, the tachometer;
stove automatic control system;
generator unit connections;
control of the power unit.
As you can see, in general, the electrical diagram of a VAZ 16-valve engine is a rather complex system. Accordingly, there are also enough breakdowns in its work, all of them can be conditionally divided into several groups.For example, if you have suspicions about the functionality of the spark plugs, but they turned out to be working, then you need to check the operation of the ignition coil and high-voltage cables. As practice shows, breakdowns in the wires can also lead to incorrect operation of the ignition system. Failure of one or another element of the electrical network can be the result of both a breakdown of the device itself and the failure of a generator unit or battery.
Most often, car owners are faced with the problem of battery failure, therefore, we will consider the main malfunctions characteristic of this device:
a short circuit has occurred between the electrodes of the device;
damage to the plates located inside;
the appearance of cracks and other mechanical damage on the battery case, as well as sprinkling of the plates, which can lead to leakage of electrolyte;
oxidation of the battery terminals, this problem can be solved by stripping.
All these malfunctions ultimately lead to battery discharge. If we talk about the reasons that caused these problems, then most likely they all lie in improper operation, of course, if the battery life is high and has not yet ended. Much less often, the malfunction lies in a factory defect, but this does not happen often.
In order to prevent malfunctions in the operation of the battery, the following rules should be taken into account during operation:
First, the device must be securely fixed in place. If the battery is not securely fixed, this can lead to constant vibration, which can subsequently cause the appearance of cracks on the case.
Car operation and, accordingly, the use of the electrical network is allowed only when using a working generator. If the alternator malfunctions, or its belt is too loose, this will ultimately lead to the discharge of the battery.
In the event that the contact at the terminal of the device is poor, this can lead to its oxidation and destruction.
The battery discharge is also facilitated by prolonged cranking of the starter when trying to start the engine. Especially often, this problem manifests itself in frost, when the battery electrolytes are less mobile, and the driver has to turn the starter longer to start it (video author - Vyacheslav Kravchenko).
Depending on the type and manufacturer, the battery can last anywhere from three to five years. However, the service life may be lower if the battery is used in intensive mode and in harsh conditions. One way or another, the consequence of a discharge of the battery is always the same - the device will not be able to crank the starter to start the engine, as well as power the devices and equipment of the car as a whole. In the event that the diagnostics showed that the battery is working normally, it is possible that the cause of the malfunction lies in the operability of the generator.
Its design as a whole is more complex, respectively, this node has enough faults:
abrasion of the brushes, which is due to their wear;
breakdown of the voltage regulator relay;
failure of the diode bridge;
bearing wear, which is accompanied by a hum when the generator is running;
wear of slip rings;
damage or wear of the pulley teeth;
short circuit in the stator winding;
damage to the charging circuit wiring;
breakage or wear of the alternator belt.
Malfunctions in the operation of the unit can be determined by diagnostics using a multimeter. As for the repair, you can do it yourself. Earlier, we have already described the procedure for repairing a generator using the example of the VAZ 2114 model in this article, in the case of the VAZ 2111 it looks similar.
As for the rest of the faults in the operation of the electrical circuit, there may be several reasons:
failure of the device itself;
blown fuse caused by a short circuit (before replacing the fuse, it is necessary to determine the cause of the short circuit);
open circuit, the problem is solved by replacing the wire;
oxidation of contacts on device terminals (video author - Ramanych channel).
In order to prevent problems in the operation of electrical equipment, it is necessary to follow certain preventive measures, in particular:
