Hva betyr feilkoden?
The SUM reads a voltage from the three Four-C switches to decide which drive program has been selected. The fault code is set when the voltage from the switches is too high, which can mean a short circuit to voltage.
Mulige årsaker
- The wire from the switches has a short circuit to voltage
- Damaged Four-C switch
Hva du kan gjøre
- 1Clear the code and road test the car, then check whether it comes back
- 2Check that the relevant fuses are intact; their locations are in the owner's manual
- 3Check that the connectors at the switches are firm and not corroded
- 4Inspect the wire from the switches for chafing and pinch damage
- 5With the switches disconnected and the ignition on, use a multimeter to check whether the wire from the switches has voltage to the body
- 6If the fault returns, have a workshop with diagnostic equipment check the switches and the wire
Symptomer du kan merke1
- Drive program selection with the switches does not work
Hva feilen kan påvirke1
