Conditions for Clearing the MIL/DTC

WARNING: This page is about a different car, the 2007 Hummer H2. However, it is still accessible from the selected car via links, so may be relevant.

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	Value(s)	Yes	No
Schematic Reference: Instrument Cluster Schematics
1	Did you perform the Diagnostic System Check - Vehicle?	-	Go to Step 2	Go to Diagnostic System Check - Vehicle
2	Install a scan tool. Raise the vehicle's drive wheels. Refer to Lifting and Jacking the Vehicle . 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 Testing for Intermittent Conditions and Poor Connections	Go to Step 3
3	Turn the ignition OFF. Disconnect the powertrain control module (PCM) connector C2. Turn the ignition ON, with the engine OFF. Measure the voltage from the vehicle speed signal circuit of the PCM to a good ground. Does the voltage measure greater than the specified value?	9.5 V	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 . Did you find and correct the condition?	-	Go to Step 10	Go to Step 6
5	Test the vehicle speed signal circuit for an open, for a short to voltage, or for a short to ground. Refer to Circuit Testing and to Wiring Repairs . Did you find and correct the condition?	-	Go to Step 10	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 . Did you find and correct the condition?	-	Go to Step 10	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 . Did you find and correct the condition?	-	Go to Step 10	Go to Step 9
8	Replace the PCM. Refer to Control Module References for replacement, setup, and programming. Did you complete the replacement?	-	Go to Step 10	-
9	Replace the IPC. Refer to Control Module References for replacement, setup, and programming. Did you complete the replacement?	-	Go to Step 10	-
10	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
