This basic setting is used to initiate the steering angle sensor. This shall be done if:
ABS control unit is replaced.
Steering angle sensor is replaced.
Error code that requires initiation of steering angle sensor is stored in the ABS control unit.
Note:
During basic setting, the ignition may not be turned off.
In vehicles with electromechanical power steering a basic setting of the power steering must be performed after initiating the steering angle sensor. Performed as follows from point 7.
Test conditions:
Battery voltage above 12V.
ABS control unit correctly coded.
Procedure:
Check that the steering wheel is in correct position when the front wheels stand straight.
Drive the car straight ahead on level ground at max. 20 km/h to check that the car does not veer when the steering wheel is held in position for driving straight ahead.
Stop the car and make sure that the front wheels and steering wheel are aligned.
Select the function: "Initiating steering angle sensor".
The function starts, a dialogue shows: ”Adaptation in order”, - confirms that initiation is performed.
If the text "Adaptation not possible" is shown, check that the steering angle sensor is installed correctly and that the steering wheel is in the middle position.
Complete the function and disconnect the diagnostic tool.
The ESP and steering servo test lamp comes on.
Test-drive a short distance straight ahead at 15 - 20 km/h (steering angle sensor in middle position). Now the control light for the stability program should turn off.
Let the engine run at idle, set the steering wheel in middle position (front wheels straight ahead) and keep this position for at least 2 seconds.
Turn the steering wheel to left full lock and hold it there until you hear 3 beeps.
Turn the steering wheel to right full lock and hold it there until you hear 3 beeps.
Turn back the steering wheel to middle position (front wheels straight ahead). The control light for electromechanical steering turns off.
Check that no error codes are stored in the ABS control unit or in the control unit for electromechanical power steering.
