For engines with the Motronic or Ecotronic ignition system, as well as for the C18NZ engine, the ignition advance is only checked, but not adjusted. If the advance is offset, the faulty components must be replaced.
Multec ignition system (except for C18NZ and EZF-h engines) requires only the initial setting of the ignition advance, without its adjustment. This must be done if the ignition distributor was removed or the timing belt was replaced. To check the ignition advance, a tachometer and a stroboscope are required.
Examination
Warm up the engine (lower radiator hose warm).
If necessary, turn off the air conditioner.
Connect the tachometer to terminals "1" and "15" of the ignition coil and the stroboscope (according to the instructions of the devices).
Start the engine and let it idle.
Illuminate the crankshaft pulley with a strobe light.
Caution! Take precautions as rotating pulley and V-belt may cause injury!
The ignition timing is set correctly if the mark on the pulley stops opposite the pointer on the housing.
If the marks do not match, it is necessary to check all elements of the ignition system, replacing the faulty ones. The 1.4 liter engine requires ignition timing adjustment.
Adjustment (1.4 and 1.6 liter engines)
Ignition system EZF-h: To adjust, disconnect the coding connector from the computer.
Multec and EZF-i ignition systems: connect contacts A and B in the diagnostic connector together.
Loosen the fastening of the distributor clamp and turn the distributor until the specified ignition timing is reached. Turning in direction A (see Fig.) leads to earlier ignition, in direction B - to later ignition.
Secure the clamping bar.
Increase the speed to 2000 rpm for a short time and check the ignition timing. Repeat the adjustment if necessary.
Turn off the engine.
Multec and EZF-i ignition systems: disconnect the diagnostic key from the diagnostic connector (or remove the jumper).
EZF-h ignition system: connect the coding connector to the computer.
