DTC P0704

Circuit Description
The clutch switch is a normally closed switch, clutch pedal released. The ECM detects an ignition voltage on the clutch switch circuit when the clutch switch is closed. The ECM detects 0 volts on the clutch switch circuit when the clutch switch is open, clutch pedal depressed.
This DTC determines if the transmission clutch switch has failed by looking for a clutch switch transition during a predetermined drive cycle.

Conditions for Running the DTC
^ No VSS DTC'S.
^ The vehicle speed is greater than 15 km/h (9 mph).
^ The brake switch remains released.

Conditions for Setting the DTC
^ The ECM must detect 20 or more gear changes with less than 6 clutch pedal transitions.
^ Time between gear changes must be 4 seconds or greater.

Action Taken When the DTC Sets
^ The ECM stores the DTC information into memory when the diagnostic runs and fails.
^ The Malfunction Indicator Lamp (MIL) will not illuminate.
^ The ECM records the operating conditions at the time the diagnostic fails. The ECM stores this information in the Failure Records.

Conditions for Clearing the MIL/DTC
^ A last test failed, current DTC, clears when the diagnostic runs and does not fail.
^ A History DTC clears after 40 consecutive warm-up cycles, if this or any other emission related diagnostic does not report any failures.
^ Use a scan tool in order to clear the MIL/DTC.
