What does this fault code mean?
The fault is intermittent, meaning it is sporadic and may not be present right now. The rear electronic module (REM) has registered too high a signal from the status flag when it controls the reversing light relay, which comes from a brief short to battery voltage in the relay control. The reversing light then does not work.
Possible causes
- The control to the reversing light relay is shorted to battery voltage
What you can do
- 1Read and clear the fault code, then check whether it returns when reverse gear is selected
- 2Check that the reversing light relay is correctly fitted
- 3Check the relay connection for loose contacts and for a short to voltage, especially where the wiring moves
- 4If the fault remains, have a workshop with diagnostic equipment investigate the relay and the wiring
Symptoms you may notice1
