Ignition module VAZ, repair and replacement with your own hands

To call the fuel-air mixture, and in injection, and in the carburetor motors of internal combustion, a high-voltage ignition coil is required. The emergence of new motor power systems in the market caused changes in the Ignition systems of the VAZ. The ignition distributors, referred to, gradually go into the past. To replace them, new devices come - VAZ 2114 ignition modules.

Module VAZ2114, device and principle

The VAZ Ignition Module is an advanced engine starting system. Its principle of operation is actually not different from standard systems. If high-voltage voltage in outdated systems was generated by disconnecting of contacts in the ignition system distributor, then the pulse generator in the module are signals supplied by the control unit.

Signals from sensors from sensors are collected on the motor and the control pulse is generated, which is sent to the ignition module. From the voltage of the on-board network, it forms high-voltage voltage and directs to the cylinder candle to ignite the air-fuel mixture.

The composition of this device includes two coils that produce high voltage. A two-channel electronic switch helps them. All elements consist in a housing of durable plastic. The housing is located low-voltage connector for feeding control pulses and connecting the supply voltage. In addition, there are conclusions here to connect high-voltage wires, which are connected to the candles.

VAZ2114 ignition module, fault signs

You can meet such signs of the vehicle ignition module of the VAZ 2114 model:

  1. On one of the candles there is no spark.
  2. Strongly floats idle.
  3. Motor power decreased significantly.
  4. Drying disappeared, during a sharp pressing of gas pedal in the engine, there were failures.

Ignition module, can the module repair is possible

In fact, all breakdowns of this device lead to its replacement, but in some cases it is still possible to repair the ignition module. This is especially possible when changing the engine behavior during tapping or movement. You can repair the module yourself, if you can handle a multimeter and a soldering iron.

You need to remove the rear metal cover, under which the electrical elements of the ignition module are located. Gently get rid of silicone, find damaged or trim contacts and read them. Do not forget that in the block aluminum conductors, so the necessary special solder for their soldering.

After that, the back cover is closed and check the performance of the module. If the result is positive, open the lid again and fill the inside with silicone. With a negative result, replace the module. Although you can still try to replace electronic switches.

Checking system for performance

In any case, the check must be started with the candles, for which we carry them out of the nests. It is very simple to do it. It should be removed from them the tips of the armored wires and remove from the seats using a special key for turning.

Then you need to examine them, clean and check. They should have brown, without soot and nagar. If the nagar is, it is quite possible that the pistons and rings were worn out. In any case, candles should be cleaned, check and, if necessary, set a gap between the electrodes. Now check their performance. Special probes exist to check them. Some drivers are capable of making it with piezoshigali. If there is nothing like that, then check on the motor. With the health of the candles, you need to continue the search further.

Tools assistants

Replace the ignition module independently every driver can not need special equipment or special skills. All that will be required to motorist:

  1. Rag.
  2. Key to 13.
  3. New ignition unit.

Ignition module 2114, replacing the module with your own hands, step by step instructions

Such works can be performed on a flat site or in the garage.

  1. First you need to open the hood of the motor compartment and disconnect the terminals of the battery. It will be enough to remove only a minority terminal.
  2. Next from the installation places, take out high-voltage wires. It is important to remember their location. If you have doubts you can make tags. You can not change the wires in some places, since the new spare part may fail.
  3. Then you need to carefully disconnect the connector with cables from the module. We take the key to 13 and unscrew the three nuts fastening the device to the engine.
  4. After removing the nuts, the device is removed from the motor.

Now we take the rag and wipe the installation site and near it.

The new device should be carefully examined, after which it is necessary to start the installation that must be carried out in the reverse order.

Do not forget to install high-voltage wires correctly. If you are still confused, pay attention to the block on which the number of armored wires is indicated.

Tips of professionals

Even though electronic devices are quite reliable, there are still breakdowns. In some cases, they can be avoided, for which it is necessary to increase and maintain all the parts of the system sometimes:

  1. Watch that there is no confusion with high voltage cables - with a large internal resistance in them, can fail the coil.
  2. Between the electrodes of candles it is necessary to check the gap, because overly large spark gaps are negatively reflected on the device.
