1	Did you perform the Diagnostic System Check - Vehicle?	Go to Step 2	Go to Diagnostic System Check - Vehicle in Vehicle DTC Information
2	Install a scan tool. Raise the vehicle drive wheels. Refer to Lifting and Jacking the Vehicle in General Information. Start the engine. Place the transmission into drive for an automatic transmission or third gear for a manual transmission. With the scan tool, observe the Vehicle Speed Sensor parameter in the PCM Engine Data 1 data list. Does the Vehicle Speed Sensor parameter match the speedometer display?	Go to Step 3	Go to Step 4
3	Does the odometer operate properly?	Go to Testing for Intermittent Conditions and Poor Connections in Wiring Systems	Go to Step 4
4	Verify that the body control module (BCM) is configured and setup correctly. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming. Is the BCM configured and setup correctly?	Go to Step 5	Go to Step 6
5	Replace the instrument panel cluster (IPC). Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming. Did you complete the replacement?	Go to Step 7	-
6	Replace the BCM. Refer to Control Module References in Computer/Integrating Systems for replacement, setup, and programming. Did you complete the replacement?	Go to Step 7	-
7	Operate the system in order to verify the repair. Did you correct the condition?	System OK	Go to Step 2
