P0704

Schematic:

CIRCUIT DESCRIPTION
The Clutch Pedal Position Switch is a normally closed switch. The PCM applies a voltage (B+) to the Clutch Pedal Position Switch circuit. When the Clutch Pedal Position Switch is depressed (clutch pedal released) the circuit is open and the PCM senses a high voltage. When the Clutch Pedal Position Switch is released (clutch pedal depressed) the Clutch Pedal Position Switch contacts close, causing the applied voltage to go low.

The PCM determines if the Clutch Pedal Position Switch has failed by not sensing a clutch switch transition. The PCM monitors vehicle speed from 0 to a predetermined speed.

CONDITIONS FOR RUNNING THE DTC
No VSS DTCs.

CONDITIONS FOR SETTING THE DTC
^ Vehicle speed goes from 0 mph to more than 24 mph and back to 0 mph for 2 seconds without the PCM detecting a clutch transition.
^ This occurs 7 times before the diagnostic reports a fault.

ACTION TAKEN WHEN THE DTC SETS
^ The PCM stores the DTC information into memory when the diagnostic runs and fails.
^ The Malfunction Indicator Lamp (MIL) will not illuminate.
^ The PCM records the operating conditions at the time the diagnostic fails. The PCM stores this information in the Failure Records.

CONDITIONS FOR CLEARING THE MIL/DTC
^ A History DTC will clear after 40 consecutive warm-up cycles, if no failures are reported by this or any other non-emission related diagnostic.
^ A last test failed (Current DTC) will clear when the diagnostic runs and does not fail.
^ Use a scan tool in order to clear the MIL/DTC.

DIAGNOSTIC AIDS

IMPORTANT:
^ Remove any debris from the PCM connector surfaces before servicing the PCM. Inspect the PCM connector gaskets when diagnosing/replacing the PCM. Ensure that the gaskets are installed correctly. The gaskets prevent contaminate intrusion into the PCM.
^ For any test that requires probing the PCM or a component harness connector, use the J 35616-A connector test adapter kit. Using this kit prevents damage to the harness/component terminals. Refer to Using Connector Test Adapters in Diagrams.

For an intermittent condition, refer to Symptoms. Symptom Related Diagnostic Procedures
