Trip Odometer / Odometer
The function of the trip odometers and the odometer is to display the three available odometer modes. The two settings are the total mileage of the car and the mileage since the two trip odometers were last set to zero. The trip odometers can be reset individually. The odometer and one of the two trip odometers are always displayed. Press the button briefly to switch between the two trip odometers. Hold the button in longer to reset the trip odometer. The driver information module (DIM) must also be powered.
The central electronic module (CEM) (4/56) receives a speed signal from the brake control module (BCM) (4/16) which is transmitted on the high speed section of the control area network (CAN). The central electronic module (CEM) then transmits the signal on to the driver information module (DIM) (5/1) via the low speed section of the control area network (CAN). The distance traveled is saved every fourth kilometer and the value is stored in the central electronic module (CEM).
