Normalizing steering column adjustment function - GF46.15-P-3002S

MODEL 215, 220 

Functional prerequisites 

• CAN must be activated, e.g. by switching on the side lights.

Function 

For normalizing the associated software stops are stored in the left front SAM control module (N10/6)  by approaching the mechanical stops of the steering column adjustment motor group (M20)  . The switching point of the microswitch for steering column driving position (M20s1)  is also stored. The switching point also serves as a reference point. If it is overshot, error compensation takes place in the position counter of the control module and any position error is corrected.

Normalizing is required during initial commissioning or after replacing an assembly.

The left front SAM control module (N10/6)  has a non-volatile memory so that the set position values are retained even after the vehicle battery is disconnected.

Normalizing tilt adjustment 

The steering column is moved manually against the front stop by operating the steering column switch.

Normalizing fore/aft adjustment 

The steering column is moved manually against the front stop by operating the steering column switch.

If the steering column is stiff or locked  the left front SAM control module (N10/6) recognizes the current position as a new software stop. Emergency running mode  is possible in spite of this.
