Odometer Trip/Reset Switch Inoperative

Odometer Trip/Reset Switch Inoperative

Diagnostic Fault Information

Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Initial Inspection and Diagnostic Overview

Circuit/System Description

The body control module (BCM) calculates the mileage based on the vehicle speed signal circuit from the powertrain control module (PCM)/engine control module (ECM). The BCM then sends a serial data message to the instrument panel cluster (IPC) indicating the value of the odometer. The odometer will display 'error' if an internal BCM memory failure is detected. The odometer display is also used as a text message display to display driver information, oil life and language.

Circuit/System Testing

1. Ignition ON, scan tool installed, press the trip reset button and verify that the odometer display toggles between the trip odometer and other vehicle information. With the scan tool, verify that the Trip Odometer Reset Switch parameter toggles between Pressed and Released when the trip reset button is pressed.

• If not, replace the IPC.
