EVAP Canister Purge Valve Output Stage - Below Limit/Above Limit

Diagnosis conditions
- Time elapsed after engine start-up greater than 10 seconds
- Battery positive voltage between 10 V and 16 V

Possible fault cause
- Short circuit to B+ in triggering wire
- Short circuit to ground in triggering wire
- EVAP canister purge valve faulty (short circuit)
- DME control module faulty

Affected terminals
DME control module connector A, pin 64, and EVAP canister purge valve connector, pin 2

Diagnosis/troubleshooting

NOTE: The wiring for fuse FE11 and fuel tank ventilation connector is routed via the KE7 disconnection point, pin 1.

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.
