Odometer Trip/Reset Switch Inoperative

ODOMETER TRIP/RESET SWITCH INOPERATIVE

DIAGNOSTIC FAULT INFORMATION

IMPORTANT: Always perform the Diagnostic System Check - Vehicle Testing and Inspection

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

CIRCUIT/SYSTEM TESTING
1. Turn ON the ignition, with the engine OFF
2. Press the trip reset button
- If the odometer display does not switch between trip and odometer, replace the IPC.

REPAIR INSTRUCTIONS

IMPORTANT: Always perform the Diagnostic Repair Verification Verification Tests
