To avoid personal injury and/or damage to the electronic ignition system, the following points must be observed when working on a vehicle with an electronic ignition system.
Do not touch the high voltage wires with your hand while the engine is running or when turning the crankshaft with the starter.
Disconnect the ignition wires only when the ignition is switched off. When the ignition is switched on, high voltage shock can occur due to the vibrations of the ignition distributor.
Connecting and disconnecting measuring instruments (crankshaft speed meter, ignition timing tester) only be carried out with the ignition off.
Do not connect an anti-interference capacitor and a test lamp to the ground connector of the ignition coil.
Do not connect measuring devices and a stroboscope to the positive connector of the ignition coil to check the ignition system with the engine running.
Do not replace the ignition coil with a coil of a different design.
It is not allowed to heat the car to a temperature of more than + 80°C (e.g. varnishing, steaming). Start the engine only after some cooling.
Wash the engine only with the ignition off.
Before performing arc and spot welding, the battery must be completely disconnected from the vehicle's on-board network.
Persons with a cardiac pacemaker should not carry out any work on electronic ignition systems.
For vehicles with catalytic converter only:
Before turning on the ignition, it is necessary to put on the tips of the high voltage wires on all spark plugs. If during maintenance it is necessary to check for the presence of an ignition spark, then this should be done only for a candle of one cylinder. At the same time, good contact of the spark plug with the ground should be ensured. When connecting the spark plug to ground (e.g. with crankcase) take the tip of the candle or, accordingly, the high voltage wire not by hand, but by a well-insulated clamp.
Before checking the compression, disconnect the fuel pump relay and disconnect the ignition coil connector.
