Did you perform the Instrument Cluster Diagnostic System Check?

Go to Step 2

Go to Diagnostic System Check - Instrument Cluster

1. Turn ON the ignition, with the engine OFF.
2. Install a scan tool.
3. With the scan tool, perform the segments test in the instrument panel cluster (IPC) scan tool output controls.

Do all of the segments of the driver information center (DIC) illuminate?

Go to Step 3

Go to Step 6

1. Install a scan tool.
2. Raise the vehicles drive wheels. Refer to Lifting and Jacking the Vehicle in General Information.
3. Start the engine.
4. Place the transmission into drive for automatic transmission or third gear for manual transmission.
5. With the scan tool, observe the Vehicle Speed Sensor (VSS) parameter in the IPC Data 1 data list.

Does the VSS parameter match the speedometer display?

Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems

Go to Step 4

Test the vehicle speed signal circuit for a high resistance between the IPC and the powertrain control module (PCM). Refer to Circuit Testing and Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 7

Go to Step 5

Inspect for poor connections at the harness connector of the IPC. Refer to Testing for Intermittent Conditions and Poor Connections and Connector Repairs in Wiring Systems.

Did you find and correct the condition?
