Section 16 (Instrument Cluster): Odometer: Operation

WARNING: This page is about a different car, the 2006 Dodge Sprinter. However, it is still accessible from the selected car via links, so may be relevant.

The odometer and trip odometer give an indication to the vehicle operator of the distance the vehicle has traveled. This indicator is controlled by the instrument cluster circuitry based upon cluster programming and electronic messages received by the cluster from the Controller Anti-lock Brake (CAB) over the Controller Area Network (CAN) data bus. The odometer and trip odometer information is displayed by the multi-function indicator Liquid Crystal Display (LCD). The LCD will display the odometer information whenever it is activated, and will display the last previously selected odometer or trip odometer information when the ignition switch is turned to the On position. The instrument cluster circuitry controls the LCD and provides the following features:

Odometer/Trip Odometer Display Toggling - Actuating the multi-function indicator "mi" (miles) or "km" (kilometers) switch push button momentarily with the LCD illuminated will toggle the display between the odometer and trip odometer information. Each time the LCD is illuminated with the ignition switch in the On or Start positions, the display will automatically return to the last mode previously selected (odometer or trip odometer).
Trip Odometer Reset - When the multi-function indicator "mi" (miles) or "km" (kilometers) switch push button is pressed and held for longer than about two seconds, the trip odometer will be reset to 000.0 kilometers (miles). The LCD must be displaying the trip odometer information in order for the trip odometer information to be reset.

The CAB continually monitors the vehicle speed pulse information received from the four wheel speed sensors, then sends the proper distance messages to the instrument cluster. For proper diagnosis of the wheel speed sensors, the CAB, the CAN data bus, or the electronic message inputs to the instrument cluster that control the odometer/trip odometer, a diagnostic scan tool is required.
