Conditions for Clearing the MIL/DTC

The history DTC clears after 40 malfunction free warm-up cycles.
The DTC becomes history when the conditions for setting the DTC are no longer present.
The PCM receives the clear code command from the scan tool.

DTC P0608

Step	Action	Yes	No
Schematic Reference: Instrument Cluster Schematics
1	Did you perform the IPC Diagnostic System Check?	Go to Step 2	Go to Diagnostic System Check - Instrument Cluster
2	Install a scan tool. Disconnect the radio. Raise the vehicles 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 2 data list. Does the Vehicle Speed Sensor parameter match the speedometer display?	Go to Step 10	Go to Step 3
3	Turn OFF the ignition. Disconnect the powertrain control module (PCM) connector C2. Turn ON the ignition, with the engine OFF. Measure the voltage from the vehicle speed signal circuit to a good ground. Does the voltage measure greater than 9.0 volts?	Go to Step 4	Go to Step 5
4	Test the vehicle speed signal circuit for a short to battery voltage. Refer to Circuit Testing and to Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 11	Go to Step 6
5	Test the vehicle speed signal circuit for an open, or for a short to ground. Refer to Circuit Testing and to Wiring Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 11	Go to Step 7
6	Inspect for poor connections at harness connector of the PCM. Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 11	Go to Step 8
7	Inspect for poor connections at the harness connector of the instrument panel cluster (IPC). Refer to Testing for Intermittent Conditions and Poor Connections and to Connector Repairs in Wiring Systems. Did you find and correct the condition?	Go to Step 11	Go to Step 9
8	IMPORTANT: Program the replacement PCM. Replace the PCM. Refer to Powertrain Control Module (PCM) Replacement in Engine Controls.Did you complete the replacement?	Go to Step 11	-
9	IMPORTANT: Perform the setup procedure for the replacement IPC. Replace the IPC. Refer to Instrument Panel Cluster (IPC) Replacement .Did you complete the replacement?	Go to Step 11	-
10	Replace the radio. Refer to Radio Replacement in Entertainment. Did you complete the replacement?	Go to Step 11	-
11	Use the scan tool in order to clear the DTCs. Operate vehicle within the Conditions for Running this DTC. Does the DTC reset?	Go to Step 2	System OK
