Parking Brake
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 CAN. When the parking brake is applied (activated) the lamp lights.
DIM indicates when the parking brake is engaged by sending both a text message warning and an audible warning simultaneously. If speed exceeds 10 km/h, a low volume audible signal will emit. If speed exceeds 25 km/h, both the volume and the frequency of the signal will increase. Neither text message or audible signals will be sent at speeds under 10 km/h.
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.
