What does this fault code mean?
The brake control module (BCM) continuously receives the information it needs from the airbag system control module over CAN and checks the communication. The code is set when the wrong airbag system unit is fitted in the car. It most often results from an installation fault at the accelerometer (IMU) unit.
Possible causes
- Installation fault at the accelerometer (IMU) unit
