Basic setting of active steering


This function performs initiation and calibration of the active steering.

If the control unit for dynamic stability control (DSC/DXC) or the steering column's connection centre (SZL) have been replaced, then these must be coded before the function can be performed.

This function must be performed after the following jobs:

Test conditions:

Procedure:

  1. Start the function.

    • The servo motor's position angle is reset.

  2. Start the engine.

  3. Set the steering wheel in horizontal position and press "OK" to perform calibration of the steering angle sensor.

  4. Turn off the engine, turn the ignition off and on, and start the engine again. Press "OK" to continue.

  5. Set the wheels to position straight ahead (visual check is enough). Press "OK" to continue.

  6. The total steering angle is read out. Now turn the steering wheel until the steering angle is 0° and press "OK".

  7. To start calibrating, press "OK" and immediately turn the steering wheel quickly back and forth around the zero position (steering wheel's existing position) max. +/-10°. For the calibration to succeed, it is important to not make too big steering movements with the steering wheel.

  8. The warning light in the combination instrument for active steering turns off when the servo motor's position angle has been calibrated correctly.

  9. Turn off the engine and turn on the ignition.

  10. Press "OK" to erase the fault memory.

    • If the steering wheel has an off-centre position when driving straight ahead after the function has been performed, check the steering angle. With an exactly centred steering wheel position, the steering angle must be 0° (+/-2°). If it deviates, repeat this function again.
