Hva betyr feilkoden?
The longitudinal accelerometer sits in the AYC sensor and sends its value to the brake control module on its own CAN wire. It is only fitted to four-wheel-drive cars. The code is set when the signal from the sensor is implausible, and the fault may come from interference, low voltage, incorrect wheel alignment or an internal fault in the sensor.
Mulige årsaker
- Interference or noise on the wires that has disturbed the AYC sensor's calculations
- Supply voltage to the AYC sensor too low
- Incorrect wheel alignment
- Internal fault in the AYC sensor
Hva du kan gjøre
- 1Check the connectors at the brake control module and the AYC sensor for contact resistance and oxidation
- 2Make sure no interference source, such as a mobile phone or radio receiver, sits too close to the AYC sensor
- 3If the code status is intermittent, poor contact or an interference source has probably been the cause; if the fault remains, have a workshop check the sensor
- 4The brake system is safety critical: do not replace the brake control module for this code, and drive carefully until the fault is fixed
Symptomer du kan merke5
- Anti-spin warning lamp on
- General yellow warning lamp on
- Anti-spin does not work
- Stability function does not work
- Anti-skid does not work
Hva feilen kan påvirke2
- Traction control (TC), stability control (SC) and active yaw control (AYC) are disabled
- Roll stability control (RSC) is disabled on cars that have it
Generell veiledning for bileiere. Feilsøking på bilen kan peke på en annen årsak.
