Steering Angle Sensor Auxilary : Communication interrupted
Check the CAN-sensor lines (X3/7, X3/4) and plugs to the central ECU for open circuit and physical damage (including check for chafing damage) Check the power supply (X3/10, X3/1) of the ESP sensors 8,3V - 14,5V Check connections of the ESP sensors. If wiring is OK and failure is still present: - change the steering angle sensor, if failure `yaw rate sensor:communication interrupted` is not present - change the central ECU, if failure `yaw rate sensor:communication interrupted` is present, too.
What you'll see
No driver-visible symptom recorded.
System reaction
ESP control off.
Diagnostic depth
The failure is reported if there is a communication error between the central ECU and the steering angle sensor.
steering angle sensor is not connected to the central ECU - damage of the sensor - if this error occurs together with error yaw rate sensor:communication interrupted - failure of the electronic CAN-component for CAN-sensor in the central ECU
