Testing ignition system
Safety precautions
To prevent injuries to persons and/or damage to the fuel injection and ignition system, the following must be noted:
-
◆ Do not touch or disconnect ignition wiring when the engine is running or turning at starter speed.
-
◆ Always switch off the ignition before connecting or disconnecting injection or ignition system wiring or tester cables.
-
◆ To operate the engine at starting speed without actually starting it (for example, to check the compression), disconnect the connector from the power output stage for the ignition coils and the connector from the injectors. After completing the work, interrogate the fault memory.
-
◆ Always switch off the ignition before connecting or disconnecting the battery, otherwise the engine control unit may be damaged.
