Function

Component Identification:

When the cruise control pushbutton switch is operated, two contacts are always closed simultaneously. The actual input is made by closure of the accelerate and set contact (storage of specified speed). The safety contact (S40s5) must close simultaneously so that the entry is accepted.

The signals from the CC [TPM] push button switch are read in by the steering column tube module and transmitted to the ESP, SPS [PML] and BAS control unit (N47-5) via the engine compartment CAN (CAN C) for evaluation.
