Function

Component Identification:

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 safety contact must close simultaneously so that the input is accepted.


The DISTRONIC distance potentiometer allows the driver to adjust the target distance to the vehicle ahead to suit his/her own personal taste.
The setting range of the target distance is divided into six increments and is approx. 1.0 s to 2.0 s depending on vehicle speed.
Within this setting range, the legally prescribed minimum distance is always guaranteed.

The CC [TPM] switch signals are read in by the steering column module (N80) and transmitted via the chassis CAN to the ESP control unit (N47-5) for evaluation.
