Fuel System

Note the following when working on the fuel system:


There is a risk of injury because the fuel is under very high pressure.

• Reduce the fuel pressure down to residual pressure before opening the high pressure area of the fuel injection system.

• To reduce remaining residual pressure, place a clean cloth around the connector and carefully loosen connector.

- Procedures before opening high pressure fuel injection system.

To prevent personal injury and damage to the injection and ignition system, observe the following:

• The ignition must be turned off before connecting or disconnecting injection and ignition system wiring or tester cables.

• Wash the engine only when the ignition is turned off.

• If electrical connectors were disconnected and the engine was started, then malfunctions have been stored in the engine control modules. "Generate readiness code" in "Guided Functions" see vehicle diagnosis tester.


Danger of causing damage to other electronic components when disconnecting the battery.

• Complete the steps for disconnecting the battery.

• Always turn off the ignition before disconnecting the battery.
