Hva betyr feilkoden?
CEM controls the power supply to the fuel filler cap lock motor through a directly connected wire. If the wire to the motor is short-circuited to voltage or ground, or has an open circuit, the fault code is set. The fuel filler cap then cannot be unlocked, or is hard to open.
Mulige årsaker

- 2Use a multimeter to check that the supply wire has no break and no contact with ground (the body) or voltage
- 3Check the connectors at the CEM and at the fuel filler lock motor for damage and corrosion
