Circuit/System Description

The BCM calculates the mileage based on the vehicle speed signal from the engine control module (ECM). The BCM then sends a serial data message to the IPC indicating the value of the odometer. The odometer will display 'error' if an internal BCM memory failure is detected or there is a serial data communication fault. The odometer displays either miles or kilometers and the desired units can be accessed by pressing the trip/reset switch.
