Hva betyr feilkoden?
The CEM runs the washer pump by switching one of two pump relays in the passenger compartment fuse box, using a ground connection on the control line. The fault shows that the control line to the rear window washer relay is shorted to voltage, so the CEM cannot control the relay correctly. The fault is checked when rear window washing is activated.
Mulige årsaker
- The control signal wire to the relay is shorted to voltage
- Damaged relay
Hva du kan gjøre
- 1Read off and note the code, clear it and run the rear window washer to see whether it returns
- 2Check that the fuses for the washer pumps are intact
- 3If you have a diagnostic tool, activate the rear washer pump with the tool and listen for the pump to start
- 4Use a multimeter (ignition off, relay connector unplugged) to check that the control wire is not at voltage
- 5If the fault remains, have a workshop check the relay and the wiring
Symptomer du kan merke2
- The rear window washer does not work
- Rear window washing is poor
