Did you perform the Diagnostic System Check - Vehicle?

Go to Step 2

Go to Diagnostic System Check - Vehicle in Vehicle DTC Information

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 vehicle 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 8

Go to Step 5

Test the VSS high signal circuit for a high resistance, a short to ground, or a short to voltage between the PCM and the transmission control module (TCM). Refer to Circuit Testing and Wiring Repairs in Wiring Systems.

Did you find and correct the condition?

Go to Step 8

Go to Step 6

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?

Go to Step 8

Go to Step 7

Replace the IPC. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming.

Did you complete the replacement?
