Task

The Cruise control switch detects the CC [TPM] switch functions operated by the driver, the Variable Speed Limiter (except code (494) USA version) and Downhill Speed Regulation.

Function

When the CC [TPM] switch is operated, two switching contacts are always activated simultaneously. The actual input takes place by closing the switching contacts (storing the target speed). The control contact must close simultaneously so that the input is accepted. Signals from the Cruise control switch are read in by the steering column module (N80) and transmitted for evaluation via the Controller Area Network (data bus/CAN bus) (CAN) to the ESP control unit (N47-5), for model 164, or to the ESP and BAS control unit (N47-5), for model 463.
