CAUTION:
Fuel system is under high pressure! Before opening high pressure components of the fuel injection system, pressure must be relieved to residual pressure →
Procedure that must be performed before opening the high-pressure fuel injection system - Pay close attention! . Then wrap a clean rag around the connection and relieve residual pressure by carefully loosening the connection.
To reduce the risk of personal injury and/or damage to the fuel injection and ignition system, always observe the following:
- The ignition must be switched off before connecting or disconnecting injection and ignition system wiring or tester cables.
- It is possible that the engine control module will recognize a malfunction and store a DTC during some tests. Therefore, when all tests and repairs are completed, the DTC memory must be checked and, if necessary, erased. After DTC memory is erased, a readiness code must be generated for the engine control module using operating mode "Guided Functions".
- Clean engine only with ignition switched off.
CAUTION:
- The battery must only be disconnected and connected with the ignition switched off, since the Engine Control Module (ECM) can otherwise be damaged.
