Diagnostic Instructions

^

Perform the [Diagnostic System Check - Vehicle Diagnostic Information] prior to using this diagnostic procedure.  See: Testing and
Inspection/Initial Inspection and Diagnostic Overview/Diagnostic System Check - Vehicle Diagnostic Information

Overview/Diagnostic Procedure Instructions - Vehicle Diagnostic Information

Circuit/System Description

The instrument panel cluster (IPC) displays the engine coolant temperature as determined by the engine control module (ECM). The IPC receives a serial
data message from the ECM indicating the engine coolant temperature.

Circuit/System Testing

Ignition ON, perform the engine coolant gage sweep test with the scan tool.

^

If the engine coolant gage does not sweep from its low to high position, replace the IPC.

Repair Instructions

Perform the [Diagnostic Repair Verification - Vehicle Diagnostic Information] after completing the diagnostic procedure.  See: Testing and
Inspection/Diagnostic Trouble Code Tests and Associated Procedures

[Control Module References] for the IPC replacement, setup, and programming. See: Testing and Inspection/Programming and Relearning
