Procedure for commissioning or adjusting the active steering (AL)

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 unit (AL)
  

• after replacing or programming the steering column switch (SZL): only E60/E61/63/64
  

• after replacing the steering column switching centre (SZL): only E90/91
  

• replacing or programming the Dynamic Stability Control (DSC)
  

• after replacing the steering gear
  

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 code memory: only E60/61/63/64
  
• Clear DSC fault code 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 code 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)
