Check of serviceability of functioning of system of ignition

In view of the fact that in systems of direct ignition very high voltage is developed, service of its components has to be made with extra care!

This remark belongs not only to the main knots of electronic system of ignition, but also and to all accompanying components, including tips of candle wires, a tachometer and the other diagnostic equipment.

If the engine is turned, but not started, disconnect VV a wire from one of spark plugs of the left number of cylinders and connect it to the special calibrated ignition tester (ask in shops of automobile accessories). In the absence of near at hand universal tester, track that the used measuring instrument suited for use in the DIS systems.

Check is made only for candles of the right number of cylinders (cylinders No. No. 1 and 3). As in system the principle of a single spark is used, need for check of pair cylinders disappears!

Connect a contact clip of the measuring instrument to a bolt or a metal arm on the block of the power unit, then turn the engine, - between an electrode and the case of a tester well distinguishable spark of bright blue color has to slip (weak intensity of a spark should be considered as its absence).

Existence of sparking confirms serviceability of giving on tension VV candles, however does not exclude probability of refusal actually of candles.

If sparking violation takes place, Check serviceability of giving of food for the coil. Check a condition of coils (see the Section Assembly of Coils of Ignition - the general information, check of a state and replacement) and sensors of provision of cranked and distributive shaft (see the Head of the Control system of the engine).

Also check serviceability of giving of alarm tension for bobbin assembly. Having disconnected an electrical wiring from assembly, connect a 12-voltny lamp sampler to the positive plug of the battery.

Use only of a lamp sampler on a light-emitting diode is allowed! Ask the assistant to turn the engine and on a blinking of the coil of a lamp connected to the socket make sure of serviceability of giving of alarm tension.

Repeat the procedure for each of bobbin assemblies.

As the module of ignition and ESM are among expensive components, performance of check of their state will be reasonable to charge to specialists of car service.
