What does this fault code mean?
Applies only to cars fitted with DSTC and RSC. The lean angle sensor in the AYC sensor measures the car's lean from side to side and sends the value to the brake control module. The code is set when the signal is faulty, which is due to an open circuit or short to ground in the wiring or to an internal fault in the AYC sensor.
Possible causes
- Open circuit or short to ground in the wiring to the AYC sensor
- Internal fault in the AYC sensor
What you can do
- 1Check the wiring between the connector and the AYC sensor for open circuits and short circuits to ground
- 2Read the lean angle sensor value with diagnostic equipment
- 3If the value is wrong, the AYC sensor may need replacing by a workshop
- 4The brake system is safety critical: do not replace the brake control module for this code, and do not work on the stability sensor yourself
Symptoms you may notice3
- Anti-spin does not work
- Stability function does not work
- Anti-skid does not work
What the fault can affect2
- Traction control (TC), stability control (SC) and active yaw control (AYC) are disabled
- Roll stability control (RSC) is disabled
General guidance for car owners. Diagnosis on the car can point to a different cause.
