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 maximum/specified speed). The safety contact (S40/4s5) 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.
