Odometer Trip/Reset Switch Inoperative

Odometer Trip/Reset Switch Inoperative

Diagnostic Instructions

* Perform the Diagnostic System Check - Vehicle prior to using this diagnostic procedure. Diagnostic System Check - Vehicle
* Review Strategy Based Diagnosis for an overview of the diagnostic approach.
* Diagnostic Procedure Instructions provides an overview of each diagnostic category.

Circuit/System Description

The instrument panel cluster (IPC) calculates the mileage based on the vehicle speed signal circuit from the powertrain control module (PCM). The PCM sends a class 2 serial data message to the IPC indicating the value of the odometer. The odometer will display 'error' if an internal IPC memory failure is detected or there is a class 2 communication fault. The odometer displays either miles or kilometers and the desired units can be accessed by pressing the trip/reset switch.

Circuit/System Testing

Ignition ON, press the trip reset button a few times to verify the odometer and trip odometer

If the odometer display does not switch between odometer and trip odometer, replace IPC.

Repair Instructions

Perform the Diagnostic Repair Verification after completing the diagnostic procedure. Verification Tests

Refer to Programing and Relearning for the IPC replacement, setup, and programming.
