Hva betyr feilkoden?
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 activates the rear fog lamp relay, which can mean a brief short to battery voltage in the relay control. The rear fog lamp does not work.
Mulige årsaker

- 3Check the relay connections for oxidation, contact resistance and loose contacts
