Co oznacza ten kod błędu?
The height sensor at the right front wheel gives a signal with too low a voltage, which the SUM interprets as a fault. The height sensor tells the SUM the body's position, so when the signal is wrong the Four-C function is switched off.
Możliwe przyczyny
- Contact resistance or oxidation in the connectors
- The signal cable from the height sensor is short-circuited to ground
- The height sensor has no power supply
- Damaged height sensor
Co możesz zrobić
- 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 that the connector at the height sensor at the right front wheel is secure and not corroded
- 4Use a multimeter to check that the signal cable is not connected to ground (the body) with the connector at the height sensor disconnected
- 5Inspect the cable from the height sensor for chafing and pinch damage, especially where the suspension moves
- 6If the fault returns, have a workshop with diagnostic equipment check the height sensor and the wiring
