Co oznacza ten kod błędu?
The suspension control module (SUM) tracks the body's up-and-down motion using three sensors. The left front sensor sends too low a voltage, which is caused by the signal wire being short-circuited to ground, the sensor lacking its supply, or a damaged sensor. Four-C is switched off.
Możliwe przyczyny
- Signal wire from the sensor is short-circuited to ground
- Sensor has no supply voltage
- Damaged acceleration sensor
Co możesz zrobić
- 1Check that the fuses for the suspension system are intact, as shown in the owner's manual
- 2Check that the connector at the left front acceleration sensor is firmly seated and not corroded
- 3Use a multimeter to check that the signal wire has no contact with ground (the body), with the ignition switched off
- 4If you have a diagnostic tool: read the sensor signal in live data while you press down the left front corner of the car, and check that the value changes
- 5If the fault remains: have a workshop check the sensor and the wiring
