DTC P0704 [MZR-CD (RF Turbo)]

BME010200700204

DTC P0704

Clutch pedal position switch circuit malfunction

DETECTION CONDITION

• The PCM monitors input voltage from the clutch pedal position switch while the engine running. If the input voltage from the clutch pedal position switch does not change when the vehicle stops after accelerating to more than 30 km/h {18.6 mph} and decelerating to 0 km/h {0 mph}, the PCM determines that the clutch pedal position switch circuit has a malfunction.
Diagnostic support note
• The MIL illuminates if the 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 the PCM detects the above malfunctioning condition.
• FREEZE FRAME DATA is available.
• The DTC is stored in the PCM memory.

POSSIBLE CAUSE

• Clutch pedal position switch malfunction
• Connector or terminal malfunction
• Short to GND in wiring harness between clutch pedal position switch terminal C and PCM terminal 33
• Open circuit in wiring harness between clutch pedal position switch terminal E and GND
• Open circuit in wiring harness between clutch pedal position switch terminal C and PCM terminal 33
• PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
• Has FREEZE FRAME DATA been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA on the repair order, then go to the next step.
2
VERIFY RELATED REPAIR INFORMATION AVAILABILITY
• Verify related Service Bulletins and/or on-line repair information availability.
• Is any related repair information available?
Yes
Perform repair or diagnostic according to the available repair information.
• If the vehicle is not repaired, then go to the next step.
No
Go to the next step.
3
VERIFY CURRENT INPUT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT
• Connect the WDS or equivalent to the DLC-2.
• Clear the DTC from the PCM memory using the WDS or equivalent.
• Start the engine.
• Is the PENDING CODE for this DTC present?
Yes
Go to the next step.
No
Intermittent concern exists.
Perform the "INTERMITTENT CONCERN TROUBLESHOOTING".
4
INSPECT CLUTCH PEDAL POSITION SWITCH CONNECTOR FOR POOR CONNECTION
• Turn the engine switch off.
• Inspect the clutch pedal position switch connector for poor connection (such as damaged/pulled-out pins, corrosion).
• Is there any malfunction?
Yes
Repair or replace the suspected terminal, then go to Step 10.
No
Go to the next step.
5
INSPECT CLUTCH PEDAL POSITION SWITCH SIGNAL CIRCUIT FOR OPEN CIRCUIT
• Turn the engine switch to the ON position (Engine off).
• Inspect the voltage at clutch pedal position switch terminal C (wiring harness-side).
• Is the voltage below 1.0 V?
Yes
Repair or replace the suspected terminal, then go to Step 10.
No
Go to the next step.
6
INSPECT CLUTCH PEDAL POSITION SWITCH GND FOR OPEN CIRCUIT
• Turn the engine switch off.
• Inspect for continuity between clutch pedal position switch terminal E (wiring harness-side) and body GND.
• Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for an open circuit, then go to Step 10.
7
INSPECT CLUTCH PEDAL POSITION SWITCH
• Inspect the clutch pedal position switch.
• Is there any malfunction?
Yes
Replace the clutch pedal position switch, then go to Step 10.
No
Go to the next step.
8
INSPECT PCM CONNECTOR FOR POOR CONNECTION
• Turn the engine switch off.
• Inspect the PCM connector for poor connection (such as damaged/pulled-out pins, corrosion).
• Is there any malfunction?
Yes
Repair or replace the clutch pedal position switch, then go to Step 10.
No
Go to the next step.
9
INSPECT CLUTCH PEDAL POSITION SWITCH SIGNAL CIRCUIT FOR OPEN CIRCUIT
• Turn the engine switch off.
• Inspect for continuity between clutch pedal position switch terminal C (wiring harness-side) and PCM terminal 33 (wiring harness-side).
• Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness for an open circuit, then go to the next step.
10
VERIFY TROUBLESHOOTING OF DTC P0704 COMPLETED
• Make sure to reconnect all disconnected connectors.
• Clear the DTC using the WDS or equivalent.
• Start the engine.
• Is the PENDING CODE for this DTC present?
Yes
Replace the PCM, then go to the next step.
No
Go to the next step.
11
VERIFY AFTER REPAIR PROCEDURE
• Perform the Repair Verification Drive Mode.
• Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
Troubleshooting completed.
