On-Board Diagnostics

Type of diagnosis:


- Continuous. But interrupted when fault criteria fulfilled and will not restart until next driving cycle.


Enable criteria:


- Engine running.


Fault criteria:


- Throttle position exceeds the maximum permissible with pedal released.


Dependents:


- None.


System reaction to a fault:


- Fuel shut-off. Main relay turned off. Throttle control in limp-home mode. Limp-home solenoid will activate 5 times in succession each time the ignition is turned on until the fault is rectified and the trouble codes cleared.


OK report:


- Accelerator pedal has been depressed at some time and then fully released. 120 s has expired since then without fault criteria being fulfilled.


Fault handling: (For more information, see .)


- CHECK ENGINE goes on immediately and can be turned off only by clearing the trouble codes.


Diagnostic help

The throttle has been open despite the driver releasing the accelerator pedal. A mechanical fault is preventing the throttle from closing.

Checking the wiring

Jiggle the wiring harness at several points and in different directions to detect intermittent breaks and short circuits. Observe the multimeter, diagnostic tool or test lamp during the check.
