Hva betyr feilkoden?
The alarm status LED in the instrument panel is controlled by the central electronic module (CEM). The fault shows that the wire to the LED is shorted to battery voltage, so the CEM cannot control the LED correctly and the alarm status is not shown. The fault is checked when the central lock is locked or unlocked.
Mulige årsaker
