Warning! Your vehicle has a microprocessor ignition system (IPSZ) high energy. A voltage of about 40,000 V is applied to high-voltage wires, and although it is not life-threatening at a low current strength, a possible electric shock when checking the ignition system can lead to serious consequences. Therefore, if you take on a high-voltage wire with the ignition on, use a thick rubber glove or, in extreme cases, pliers with insulated handles.
You will need: Flat and Phillips screwdrivers, pliers with insulated handles and a tester.
Helpful advice. Before checking the ignition system, place the shift lever in neutral and leave the parking brake applied.
1. With the ignition off, check the integrity and fit of the high-voltage wires in the ignition module.
2. Disconnect the harness connector from the low voltage circuit block of the ignition module,
3. Using the tester, switched on in the low current measurement mode, check the low-voltage circuit of the module for an open circuit by connecting the tester probes to the contacts «WITH» and «IN» pads.
4. If the low voltage circuit of the ignition module is good, check for a spark at the spark plugs to test the high voltage circuit of the module and the high voltage wires. Remove the high voltage wire from any spark plug. Insert a spare spark plug into the end of the wire and press it with the metal part against «mass» car. Turn the engine crankshaft with the starter.
5. If there is no spark, replace the high voltage wires with new ones. You can first try to install non-new, but verified, with «working» cars.
6. If there is no spark after replacing the wires, replace the ignition module (see «Removal and installation of the ignition module»).
7. If there is a spark, but The engine will not start, replace the spark plugs with new ones. You can first try to install non-new, but verified, with «working» cars.
8. If after that the engine does not start, check the engine management system (see further subsection «Fuel Injection System Malfunctions»).
