Procedure For Commissioning or Adjusting the Active Steering (AL) (AL Active Steering)

Procedure for commissioning or adjusting the active steering (AL) (AL active steering)

The service function Commissioning/Adjusting active steering must be run during or after the following work:
- axle alignment/wheel alignment (see Note)
- work on the steering column
- after replacing or programming the active steering control module (AL)
- after replacing or programming the steering column switching center (SZL): only E60/E61/63/64
- after replacing the steering column switching center (SZL): only E90/91
- replacing or programming the Dynamic Stability Control (DSC)
- after replacing the steering gear

NOTE: The sequence for Commissioning/Adjustment in the service function is as follows:

- Default setting of the cumulative steering angle sensor exactly to zero for any axle alignment/wheel alignment. Choice of calling up (see Note)
- Reset the engine location angle (AL)
- Run a steering-angle sensor adjustment (E60/61/63/64: SZL, E90/91: DSC)
- Clear SZL fault memory: only E60/61/63/64
- Clear DSC fault memory
- Calibrate the engine location angle (AL)
- If ARS is included as an option, clear the value for steering angle (ARS): only E60/61/63/64
- Clear AL fault memory
- Calibrate total steering angle offset (AL): only E60/61/63/64 from 09/2005 and E90/91 after replacement of the steering gear

NOTE:
Only perform axle alignment/wheel alignment if:
- The diagnosis of the active steering leads to no defect (fault entry) and there is a deviation in the position of the steering wheel
- The guided troubleshooting on fault entry 'active steering' concludes with the with defect 'Wheel alignment'
- Repair measures are carried out that make axle alignment/wheel alignment necessary (see corresponding repair instructions)
