This function is used to zero-compensate the value from the steering angle sensor.
This must be done if:
The ABS control unit has been replaced.
The steering angle sensor has been replaced.
The steering column has been replaced.
Bodywork that affects the wheel alignment has been done.
The steering angle sensor has been disconnected.
An error code that requires zero compensation is stored in the ABS control unit.
Decalibration have been performed.
Note:
Before the steering wheel angle sensor is disconnected/replaced decalibration must be performed.
Even if only a calibration is performed a decalibration must first be performed.
During calibration the ignition must not be switched off.
The calibration must be performed in three consecutive steps.
Performance:
Decalibration:
Choose function: Steering angle decalibration.
A dialog presents: Operation succeeded/ failed.
Press OK.
The fault code: “Steering angle sensor” is stored in the fault memory.
Calibration:
Check that the steering wheel is in the correct position when the front wheels are straight ahead.
Drive the car straight ahead on a flat surface to check that the car does not pull to one side when the steering wheel is held in the straight ahead position.
Stop the car and make sure that the front wheels and the steering wheel are aligned.
Choose function: Steering angle calibration step 1.
A dialog presents: Operation succeeded/ failed.
Press OK.
Choose function: Steering angle calibration step 2.
A dialog presents: Operation succeeded/ failed.
Press OK.
Choose function: Steering angle calibration step 3.
A dialog presents: Operation succeeded/ failed.
Press OK.
Erase the stored fault code.
Test drive and check that the value for the steering angle in data list 5 is within ±5°.
