External Yaw Rate Sensor : 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 Check connections of the ESP sensors. If wiring is OK and failure is still present: - change the yaw rate sensor, if failure `steering angle sensor:communication interrupted` is not present - change the central ECU, if failure `steering angle 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 yaw rate sensor.
yaw rate sensor is not connected to the central ECU damage of the sensor if this error occurs together with error steering angle sensor:communication interrupted - failure of the electronic CAN-component for CAN-sensor in the central ECU
