ACTION
DTC P0704
Clutch switch circuit malfunction
DETECTION
CONDITION
• PCM monitors changes in input voltage from clutch switch. If PCM does not detect PCM terminal 1R
voltage changes while running vehicle with vehicle speed below 30 km/h {19mph} 8 times alternately,
PCM determines that clutch switch circuit has malfunction.
Diagnostic support note
• This is a continuous monitor (CCM).
• MIL illuminates if PCM detects the above malfunction condition in two consecutive drive cycles or in one
drive cycle while the DTC for the same malfunction has been stored in the PCM.
• PENDING CODE is available if PCM detects the above malfunction condition during first drive cycle.
• FREEZE FRAME DATA is available.
• DTC is stored in PCM memory.
POSSIBLE
CAUSE
• Clutch switch malfunction
• Poor connection of clutch switch connector or PCM connector.
• Short to ground between clutch switch terminal B and PCM connector terminal 1R.
• Open harness between clutch switch terminal B and PCM connector terminal 1R.
• Open harness between ground and clutch switch terminal D.
• PCM malfunction
