Leakage Diagnosis Pump Output Stage - Below Limit

Diagnostic conditions
- Battery voltage between 10 V and 16 V
- Time after the engine is started longer than 10 seconds

Possible cause of fault
- Short circuit to ground in triggering wire
- Leakage diagnosis pump faulty (short circuit)
- DME control module faulty

Affected pins
DME control module connector A, pin 25, and leakage diagnosis pump connector, pin 2

Diagnosis/troubleshooting

NOTE: The line for DME control module connector A, pin 25, and leakage diagnosis pump, pin 2, is routed via disconnection point KE 3, pin 9.

NOTE: If connector A is disconnected from the DME control module and the ignition is or was switched on, the 'DME Control Module TIMEOUT' fault is recorded in many control modules.

NOTE: If control module connector A was disconnected from the DME in the course of troubleshooting or if the voltage supply was interrupted elsewhere (battery, fuse), the throttle adjusting unit must be adapted.
