3.1.3. Check of system of ignition

Prevention On your car the microprocessor system of ignition (MPSZ) of high energy is established. Tension is brought to high-voltage wires about 40 000 In and though at a small current it is not life-threatening, the possible blow a current at check of system of ignition can lead to serious consequences. Therefore, if you undertake a high-voltage wire at the included ignition, use a thick rubber glove or as a last resort пассатижами with the isolated handles.

Good advice Before check of system of ignition establish the gear shifting lever in neutral situation and leave included the parking brake.

1. At the switched-off ignition check an integrity and landing of high-voltage wires in nests of the coil of ignition.

2. Check serviceability of the coil of ignition (see. «Check of the coil of ignition»).

3. If the low-voltage chain of the coil of ignition is serviceable, check spark existence on spark plugs. Remove a high-voltage wire from any spark plug. Insert into a wire tip a spare spark plug and press it a metal part to "mass" of the car (for example, to an inlet pipe). Ask the assistant to turn a starter a cranked shaft of the engine.

Preventions Reliable contact of the case of a candle to "weight" is obligatory, as at emergence of an additional spark interval, bigger, than a gap between candle electrodes, damage of the block of a control system by the engine or a high-voltage chain of the coil of ignition is possible. The specified check spend no more than five seconds not to damage converter of the fulfilled gases at hit in it the engine which has not burned down in cylinders of gasoline.

4. If the spark is not present, replace high-voltage wires new. It is possible previously to try to establish old, but checked, from the "working" car.

5. If after replacement of wires the spark did not appear, replace the ignition coil (see. «Removal and installation of the coil of ignition»). If the spark is, but the engine is not got, replace spark plugs new. It is possible previously also to try to establish old, but checked, from the "working" car.

6. If after that the engine is not got, check serviceability of a control system of the engine (see. «Malfunctions of system of injection of fuel»).
