What does this fault code mean?
One of the sensors in the AYC sensor has an incorrect offset value, meaning the correction that compensates for the sensor's own deviation. This most often means the sensor is fitted incorrectly or its bracket is damaged. The code only applies to cars with DSTC.
Possible causes
- AYC sensor incorrectly fitted
- Loose AYC sensor
- Bent bracket for the AYC sensor
- Internal fault in the AYC sensor
What you can do
- 1Check that the AYC sensor is firmly secured and correctly fitted to the bracket under the front passenger seat
- 2Make sure the bracket is not bent or otherwise damaged
- 3Correct any faults in the fitting and clear the code
- 4The brake and stability systems are safety-critical, so have a workshop carry out any work on the sensor and the module
