Hva betyr feilkoden?
CEM registers too low or no input from the rheostat while the ignition is on and the dimmer is idle. The cause may be a rheostat short to ground, a break in the signal wire or a damaged light switch. The fault shows as instrument and button lighting that does not work.
Mulige årsaker
- The rheostat is short-circuited to ground
- Break in the signal wire
- Damaged light switch
Hva du kan gjøre
- 1If you have a diagnostic tool, set the light switch to position 1 or 2 and watch the live data value while turning the dimmer; it should change
- 2If the value does not change, the fault is probably permanent; if it changes, the fault was present earlier but is not active now
- 3Use a multimeter to check that the signal wire to the dimmer has no contact with ground (the body)
- 4Check the connectors at the light switch and at the CEM for loose connections and corrosion
- 5If the wiring is intact and the fault remains, a workshop should replace the light switch
