The sensor for the parking brake is directly connected to the central electronic module (CEM). A signal which indicates whether the parking brake is applied or not is transmitted from the sensor to the central electronic module (CEM) (4/56). The central electronic module (CEM) sends the signal on to the driver information module (DIM) (5/1) via the controller area network (CAN). When the parking brake is applied (activated) the lamp lights.

The driver information module (DIM) can be programmed so that the driver is also warned by an audible signal that the parking brake is activated.
