AFS Programming

MODEL
E60 (5 Series)
E61 (5 Series Sports Wagon)
E63 (6 Series Coupe)

SITUATION
Active Front Steering (AFS) control module cannot be programmed.

CAUSE
There can be a communication error between the two processors in the AFS control module. The following factors may also cause programming failures:

^ Programming interruption (tester is switched off during the programming process).

^ Low vehicle voltage (vehicle is not connected to the charger during programming).

^ Swapped control module (two different VIN numbers may be read).

CORRECTION
If the programming is interrupted or freezes while the AFS is being programmed, perform battery reset for 5 minutes. Then, subsequent programming can be initiated. AFS control module communication and programming have been optimized in 09/05.
