Ignition System

Ignition System

To reduce the risk of personal injury and/or damage to the fuel injection and ignition system, always observe the following:

• Individuals with a pacemaker must not stay in the danger area of high voltage systems, for example ignition systems, xenon light.

• Fuel lines must not be opened when engine is running.

• Only disconnect and reconnect wires for injection and ignition system, including test leads, when ignition is switched off.

• If engine is to be cranked at starting RPM without starting (for example for compression testing), disconnect connectors from ignition coils and remove fuse for electric fuel pump.

• It is possible that the control module will recognize a malfunction and store a Diagnostic Trouble Code (DTC) during some tests. After completing all checks and repairs, check the DTC memory and erase the memory, if necessary.

• If the DTC memory was erased, a new readiness code must be generated.

• Cleaning the engine should only be performed with ignition turned off.

• The battery must only be disconnected and connected with the ignition turned off, since the Engine Control Module (ECM) can otherwise be damaged.

• If engine is to be cranked at starting RPM without starting (for example for compression testing), disconnect the four connectors for ignition coils, using the ignition coil puller (T40039). Also remove fuse from Fuel Pump (FP) control module (J538).
