Warning! The ignition module generates high voltage (up to 25 kV), which is dangerous to human health. Therefore, when performing any work related to the ignition system, observe safety precautions when servicing and repairing the car.
1. Prepare the car for maintenance and repair, disconnect the wire terminal from the negative terminal of the battery.
2. If the engine does not start, check the fuse Ef9 (IGN COIL) 15 A in the fuse and relay box. We replace the faulty fuse. If the fuse blows again, look for a short circuit in the electrical equipment in the electrical circuit of the ignition system and injectors.
3. Overcoming the resistance of the clamps, remove the ignition module cover.
4. We extend the stopper...
...press the lock...
...and disconnect the wiring harness connector from the ignition module.
5. Using a multimeter in ohmmeter mode, check the connection of contact B to the "ground". The circuit resistance should not exceed 5 Ohms. Otherwise, repair the damage.
6. To check the power supply circuit, connect the multimeter probes in voltmeter mode to the ground and contact A of the wiring harness connector and turn on the ignition. The multimeter should show the battery voltage. If there is no voltage, we fix the problem.
7. Using a TORX T40 key, unscrew the two mounting bolts...
...and remove the module together with the spark plug tips.
8. Inspect the module and spark plug tips; if cracks or other damage are detected, replace the module.
9. Install the parts in reverse order. Before installation, apply technical petroleum jelly to the inner surface of the ignition module tips to a depth of 2 mm. Tighten the module mounting bolts to a torque of 8 Nm.
