What does this fault code mean?
The signal from the acceleration sensor on the right front shock absorber is too high. The sensor gives the suspension control module information about the vertical movement of the wheel, and Four-C control is switched off.
Possible causes
- Short to voltage in the signal cable
- Defective acceleration sensor
What you can do
- 1Check the connectors at the sensor and at the control module for loose or oxidised connections
- 2Use a multimeter to check that the signal cable from the sensor on the right front shock absorber has no contact with positive voltage
- 3If you have a diagnostic tool: read live data for the right front sensor and see whether the value changes when the front wheel moves
- 4If the cable is intact, the sensor is probably defective. Have a workshop replace it
