IGNITION COIL OPERATION CHECK
Check for a spark across the tips of spark gap SP-02 after making the appropriate connections via start-up transition or by means of active diagnosis in CONTROL UNIT TEST mode. In the case of start-up transition, the petrol/methane solenoids supply pump must be interrupted so as not to damage the Lambda sensor or catalytic convertor.
| STEP | CHECK TO BE PERFORMED | REMEDIAL ACTION IF THE CHECK IS NOT OK |
|---|---|---|
| 1 | IGNITION SIGNAL CHECK - Make sure that the ignition key is in the STOP position - Disconnect the negative battery terminal - Disconnect fuse F21 for the 15 A pump in the engine compartment fuse control unit - Remove the HV coil from its housing - Insert spark gap SP-02 n° 1,806,369,000 between the HV output of the single coil and the engine block earth as shown in the following diagram, using adaptor cable N° 3 - Turn the key to the AVV position - Check that there is a spark between the probes of spark gap SP-02. - Repeat the same test on the other coils. - Use the test station to check for and delete any errors | - Reset the single 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 - If the control signal is interrupted: restore the continuity of the wiring between the engine control unit and the coil. - If the control signal coming out of the control unit is interrupted, replace the engine management control unit |
