Steering column adjustment

Electrical steering column adjustment is controlled by the Front Electronic Module (FEM) in the following situations:

• In the case of manual steering column adjustment, the driver's choice is read in by the steering column switch cluster (SZL) and transmitted to the Front Electronic Module (FEM) via the local interconnect network bus. The Front Electronic Module (FEM) processes the data and transmits the activation command to the steering column adjustment via a local interconnect network bus. The steering column adjustment drives the electrical steering column with 2 direct current motors. One direct current motor adjusts the steering column vertically and the other direct current motor adjusts it axially.
• In addition to manual adjustment, it is also possible to activate the electrical steering column via the memory function. The memory function is operated via the seat module. The seat module transmits the status of an activated memory button to the Front Electronic Module (FEM) via the CAN. The Front Electronic Module (FEM) processes the stored data, transmits the activation command to the steering column adjustment via a local interconnect network bus, and the steering column adjustment carries out the activation command using the two direct current motors.
• Furthermore, the steering column can be moved electrically when the driver gets in or out. The door contact transmits a signal to the Front Electronic Module (FEM) that a vehicle entry or exit process is pending. The Front Electronic Module (FEM) generates and transmits an activation command to the steering column adjustment.
