Hva betyr feilkoden?
The SUM supplies voltage to the Four-C sensors in two groups. The supply to the sensors on output A has too high a voltage, which can mean a short circuit to voltage. Output A supplies the body acceleration sensors and the height sensors for the right front and right rear wheels.
Mulige årsaker
- One sensor supply wire has a short circuit to voltage
Hva du kan gjøre
- 1Read and note the code, clear it and road test to see whether it returns
- 2Check that the relevant fuses are intact; their locations are in the owner's manual
- 3Check the connectors at the sensors on output A: the height sensors for the right front and right rear wheels and the body acceleration sensors
- 4Inspect the wiring to the sensors for chafing and pinch damage, especially where it moves with the suspension
- 5With the sensors disconnected and the ignition on, use a multimeter to check whether the supply wires have voltage to the body
- 6If the fault returns, have a workshop with diagnostic equipment check the sensors and their supply
Symptomer du kan merke2
- A message appears in the information display
- The Four-C function does not work
Hva feilen kan påvirke1
