What does this fault code mean?
Applies only to cars fitted with DSTC. The yaw rate, lateral acceleration and lean angle sensors are built into the AYC sensor and send their readings to the brake control module. Each sensor has an offset correction value, and the code is set when the lateral accelerometer offset is wrong. Common causes are that the sensor has been fitted incorrectly, is loose, or has a bent bracket.
Possible causes
- AYC sensor incorrectly fitted
- AYC sensor loose or its bracket bent
- Internal fault in the AYC sensor
- Stability sensor (BSC) incorrectly fitted, loose or with a bent bracket
What you can do
- 1Check that the AYC sensor is firmly fitted and correctly mounted on the bracket under the front passenger seat
- 2Make sure the bracket has not been bent or damaged in some other way
- 3Do not replace the brake control module for this code; have a workshop repair the sensor or bracket after fault-finding
- 4The brake system is safety critical: drive carefully until the fault is fixed, as the stability system does not work, and do not work on brake system sensors yourself
Symptoms you may notice5
- Anti-spin does not work
- Stability function does not work
- Anti-skid does not work
- Information lamp on
- Traction control does not work
What the fault can affect3
- Traction control (TC) and stability control (SC) are disabled
- Active yaw control (AYC) is disabled
- Roll stability control (RSC) is disabled on cars that have it
General guidance for car owners. Diagnosis on the car can point to a different cause.
