What does this fault code mean?
The current from the solenoid at the right rear wheel is too high. This may be caused by the power supply wire being short-circuited to voltage, or by a defective solenoid. The Four-C function is blocked.
Possible causes
- The power supply wire to the solenoid has contact with voltage (positive)
- Defective solenoid
What you can do
- 1Check the connectors at the solenoid at the right rear for oxidation
- 2Use a multimeter to check that the power supply wire to the solenoid has no contact with positive voltage
- 3Check that the suspension system fuses are intact; the owner's manual shows where they are
- 4If the wire is intact, the solenoid is probably defective. Have a workshop check it
