Calibration Required
The chassis control module reports that a sensor or system calibration must be performed — for example after replacement of the steering angle, yaw rate or radar sensor. Affected functions remain disabled until calibration is completed.
Affected components
- Steering angle sensor
- Yaw rate sensor
- Acc radar sensor
- Chassis control module
Common causes
- High likelihood: Required calibration not performed after service
- Medium likelihood: Calibration drive cycle incomplete
Possible symptoms
- ABS warning light on
- ESC/stability control deactivated
- Possible reduced brake assist
- Speedometer may behave erratically
