General notes: Encoding

After replacement, the EHC control unit must be encoded.

Carry out ride height adjustment. 

Ride height adjustment must be performed after the following servicing operations:

• Replacement of the control unit for the single-axle ride height control system (EHC control unit); up to 08/2010 only
• Replacement or repair of one or of both ride height sensors or their coupling bar
• Repair to the lines of the ride height sensor

To calibrate the ride height, the vehicle ride height measured at the rear axle (actual ride height on the left and right) must be entered in the diagnosis system. To do so, select the service function "Ride height calibration" on the diagnosis system. For details on how to proceed, refer to repair instructions.
