Calibration steering angle sensor
This function is used to calibrate the steering angle sensor.
The calibration must be done in the following cases:
The control unit has been replaced.
Front or rear axle adjustment has been performed.
Front or rear steering angle sensor for the electronically controlled rear axle has been replaced.
The centering cylinder has been replaced.
Note:
Caution, as the wheels rotate automatically.
The calibration values will not be saved until the end of the function.
Test conditions:
Parking brake applied.
Extra axles (if fitted) must be lowered.
Vehicle must be without load.
Engine running.
Vehicle stationary.
The control box for the suspension must be in position MAN1.
Procedure:
Set the steering gear in straight ahead position with the steering wheel.
Check that the steering gear is in straight ahead position using the mark on the steering axle and the steering gear.
Check that the drive and running wheels are in the straight ahead position using a measuring equipment.
Start the engine.
Start the function.
The calibration is initiated.
In the next step, check the signal voltage for the "front steering angle sensor".
If the value is within the allowed range (0 ±0,5 V), proceed and calibrate the zero position.
Set the zero position on the steerable rear axle.
If the value is within the allowed range (0 ±0,5 V), proceed and calibrate the zero position.
The values are permanently saved in the next dialogue box.
Turn off the ignition and wait 10 seconds.
Turn on the ignition.
The function is done.
If the function fails, check the test conditions and repair any faults.
