IGNITION COIL OPERATION CHECK

Check 5510CI

1.2 8v

Check for a spark across the tips of spark gap SP-02 after making the appropriate connections using an Examiner in active diagnosis in CONTROL UNIT TEST mode.

STEP	CHECK TO BE PERFORMED	REMEDIAL ACTION IF THE CHECK IS NOT OK
1	IGNITION SIGNAL CHECK Remove the air filter Connect an Examiner to the engine control unit and select Coil Test in active diagnosis Insert spark gap SP-02 n° 1,806,369,000 between the coil HV output and earth on the engine block, as shown in the diagram. Activate the active diagnosis of the coil concerned Check that there is a spark between the probes of spark gap SP-02. Repeat the same test on the other coils. Reposition the air filter	Restore the coil primary winding control circuit. Replace the coil Op. 5510C14 IGNITION COIL/S - R.R. if the control signal on the coil primary winding is present Restore the correct earth connection for the coil If the control signal is interrupted: restore the continuity of the wiring between the engine control unit and the coil. If the control signal at the control unit output is interrupted, replace the engine management control unit Op. 1056B82 INJECTION/IGNITION SYSTEM E.C.U. (ONE) - R + R
