Hva betyr feilkoden?
CEM controls the brightness of the instrument lighting through an output. If the output to the instrument lighting is short-circuited to ground, the fault code is set and the instrument lighting does not work. Whether the fault is permanent or intermittent is checked by activating the lighting.
Mulige årsaker
- Signal wire to the instrument lighting short-circuited to ground
Hva du kan gjøre
- 1Switch the ignition on and activate the instrument lighting; it should light at full strength when activated
- 2If it does not light, the fault is probably permanent; if it lights, the fault was present earlier but is not active now
- 3Use a multimeter to check that the control signal wire has no contact with ground (the body)
- 4Check the connectors at the light switch and at the CEM for loose connections and corrosion
- 5Remedy what is found, and if the wires are intact a workshop should replace the light switch
Symptomer du kan merke1
- Instrument lighting does not work
