Circuit/System Testing
NOTE
If the suspect gage is the speedometer, the
drive wheels of the vehicle must be raised
and the transmission must be placed in drive
or first gear.
1. Ignition ON, with the scan tool, perform the IPC
Gage Sweep Test in the IPC Output Controls. Verify
that all gage dials move from minimum to the
maximum value and back to the gage minimum
value.
➢ If the gage does not perform the IPC Gage Sweep
Test, replace the IPC.
2. Start the engine, with the vehicle drive wheels raised
and place the transmission in drive or first gear.
Verify that the speedometer value matches the scan
tool Vehicle Speed parameter in the ECM/PCM
Engine Data List.
➢ If the speedometer is incorrect, test or replace the
IPC.

Odometer Trip/Reset Switch Inoperative

Diagnostic Instructions
• Perform the "Diagnostic System Check - Vehicle
Diagnostic Information: " prior to using this diagnostic
procedure.
• Review "Strategy Based Diagnosis: " for an overview
of the diagnostic approach.
• "Diagnostic Procedure Instructions - Vehicle
Diagnostic Information: ".
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
the vehicle speed information via high speed GMLAN
serial data to the body control module (BCM). The BCM
then sends the information via low speed GMLAN 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
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
trip and odometer, replace the IPC.
