DTC
P0704
Clutch switch input circuit malfunction
DESCRIPTION
• DTC P0704 indicates malfunction of neutral or clutch switch.
[Possible Cause]
• Crank engine while in self test
• Starter interlock switch disconnected during OBD Test
• Clutch switch circuit shorted to power
• Damaged clutch or neutral switch
• Damaged PCM
STEP
INSPECTION
ACTION
1
Note
• During self test, clutch pedal must be
pressed down and gearshift lever in
NEUTRAL.
• Key off.
• NGS tester connected.
• Key on, engine off.
• Look for CPP/PNP PID cycling ON/OFF
with:
• Transaxle in neutral, then shift into gear
and clutch pedal up.
• Transaxle in gear and clutch pedal up
then down.
• Does reading change from ON to OFF
for both switches?
Yes
Fault intermittent DISCONNECT PCM.
INSPECT both ends of connector for damaged or pushed
out pins, corrosion and loose wires.
SERVICE as necessary.
If okay, REPLACE PCM.
RERUN OBD Test.
No
Go to next step.
2
CHECK CLUTCH/NEUTRAL SWITCHES
• Key off.
• Located clutch switch near clutch pedal
and neutral switch near transaxle shift
linkage.
• Inspect both switches and brackets for
damage. Service as required.
• Disconnect clutch and neutral electrical
vehicle harness connector and inspect for
damage, pushed out or broken pins and
broken wires. Service as required.
• Measure resistance across clutch switch
terminals with clutch pedal down.
• Measure resistance across neutral switch
terminals with shift lever in neutral.
•
Is resistance less than 5.0 ohms for both
switches?
Yes
Go to next step.
No
REPLACE damaged clutch or neutral switch.
RECONNECT components.
RERUN OBD Test.
3
CHECK RESISTANCE OF
CLUTCH/NEUTRAL CIRCUIT
• Key off.
• Disconnect NGS tester.
• Disconnect PCM. Inspect for damaged or
pushed out pins, corrosion and loose wires.
Service as required.
• Install breakout box. Leave PCM
disconnected.
• Measure resistance between Test Pin 91 at
breakout box and same test pin 91 at
clutch and neutral vehicle harness
connector.
<*
Is each resistance less than 5.0 ohms?
Yes
Go to next step.
No
SERVICE open circuit.
REMOVE breakout box.
RECONNECT all components.
RERUN OBD Test.
4
CHECK CLUTCH/NEUTRAL CIRCUIT FOR
SHORT
• Key off.
• NGS tester disconnected.
• Breakout box installed PCM disconnected.
• Clutch and neutral vehicle harnesses
disconnected.
• Measure resistance between Test Pins 64
and 91 at breakout box and chassis
ground.
• Is resistance greater than 10,000 ohms?
Yes
REPLACE PCM.
REMOVE breakout box.
RECONNECT all components.
RERUN OBD Test.
No
SERVICE short circuit.
REMOVE breakout box.
RECONNECT all components.
RERUN OBD Test.
