DTC P0704:00 [MZR-CD 2.2]

id0102f3706600

DTC P0704:00

Clutch pedal position (CPP) switch circuit malfunction
DETECTION CONDITION
•  The PCM monitors input voltage from the CPP switch while the engine running. If the input voltage from the CPP 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 CPP switch circuit has a malfunction.
Monitoring condition
•  Battery voltage: 8—20 V
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 malfunction condition during the first drive cycle.
•  FREEZE FRAME DATA (mode2) and snapshot data are available.
•  DTCs are stored in the PCM memory.
POSSIBLE CAUSE
•  CPP switch connector or terminal malfunction
•  Short to ground in wiring harness between CPP switch terminal A and PCM terminal 2AL
•  Open circuit in wiring harness between CPP switch terminal B and ground
•  CPP switch malfunction
•  PCM connector or terminal malfunction
•  Open circuit in wiring harness between CPP switch terminal A and PCM terminal 2AL
•  PCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION
1
VERIFY FREEZE FRAME DATA (MODE2) OR SNAPSHOT DATA HAVE BEEN RECORDED
•  Have FREEZE FRAME DATA (mode2) or snapshot data been recorded?
Yes
Go to the next step.
No
Record the FREEZE FRAME DATA (mode2) and snapshot data on the repair order, then go to the next step.
2
VERIFY RELATED SERVICE INFORMATION AVAILABILITY
•  Verify related Service Information availability.
•  Is any related Service Information available?
Yes
Perform repair or diagnosis according to the available Service Information.
•  If the vehicle is not repaired, go to the next step.
No
Go to the next step.
3
VERIFY CURRENT INPUT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine.
•  Perform the Pending Trouble Code Access Procedure.
•  Is the PENDING CODE for this DTC present?
Yes
Go to the next step.
No
Intermittent concern exists.
Perform the “INTERMITTENT CONCERN TROUBLESHOOTING”.
(See INTERMITTENT CONCERN TROUBLESHOOTING [MZR-CD 2.2].)
4
INSPECT CPP SWITCH CONNECTOR FOR POOR CONNECTION
•  Switch the ignition to off.
•  Inspect the CPP 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 CPP SWITCH SIGNAL CIRCUIT FOR SHORT TO GROUND
•  Switch the ignition to ON (Engine off).
•  Inspect the voltage at CPP switch terminal A (wiring harness-side).
•  Is the voltage less than 1.0 V?
Yes
If the short to ground circuit could be detected:
•  Repair or replace the wiring harness for a possible short to ground.
If the short to ground circuit could not be detected:
•  Replace the PCM (short to ground in the PCM internal circuit).
Go to Step 10.
No
Go to the next step.
6
INSPECT CPP SWITCH GROUND FOR OPEN CIRCUIT
•  Switch the ignition to off.
•  Inspect for continuity between CPP switch terminal B (wiring harness-side) and body ground.
•  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 CPP SWITCH
•  Inspect the CPP switch.
•  Is there any malfunction?
Yes
Replace the CPP switch, then go to Step 10.
(See CLUTCH PEDAL REMOVAL/INSTALLATION.)
No
Go to the next step.
8
INSPECT PCM CONNECTOR FOR POOR CONNECTION
•  Switch the ignition to off.
•  Inspect the PCM 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.
9
INSPECT CPP SWITCH SIGNAL CIRCUIT FOR OPEN CIRCUIT
•  Switch the ignition to off.
•  Inspect for continuity between CPP switch terminal A (wiring harness-side) and PCM terminal 2AL (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 P0704:00 COMPLETED
•  Make sure to reconnect all disconnected connectors.
•  Clear the DTC from the PCM memory using the M-MDS.
•  Start the engine.
•  Perform the Pending Trouble Code Access Procedure.
•  Is the PENDING CODE for this DTC present?
Yes
Repeat the inspection from Step 1.
•  If the malfunction recurs, replace the PCM.
Go to the next step.
No
Go to the next step.
11
VERIFY AFTER REPAIR PROCEDURE
•  Perform the “AFTER REPAIR PROCEDURE”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [MZR-CD 2.2].)
No
DTC troubleshooting completed.
