Diagnostic Procedure

DTC P0704:00 (SKYACTIV-G 2.0, SKYACTIV-G 2.5) - DIAGNOSTIC PROCEDURE

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA (MODE 2)/SNAPSHOT DATA HAS BEEN RECORDED Has the FREEZE FRAME DATA (Mode 2)/snapshot data been recorded?	Yes	Go to the next step.
1		No	Record the FREEZE FRAME DATA (Mode 2)/snapshot 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 diagnosis according to the available repair information. If the vehicle is not repaired, go to the next step.
2		No	Go to the next step.
3	INSPECT CPP SWITCH CONNECTOR CONDITION Switch the ignition off. Disconnect the CPP switch connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 11.
3		No	Go to the next step.
4	VERIFY IF MALFUNCTION OCCURS DUE TO FOREIGN OBJECT LODGED BETWEEN CLUTCH SWITCH PLUNGER AND CLUTCH PEDAL CONTACT SURFACE Visually verify the area between the clutch switch plunger and clutch pedal contact surface. Is there a lodged foreign object?	Yes	Remove the foreign object, then go to the next step.
4		No	Go to the next step.
5	INSPECT CPP SWITCH Inspect the CPP switch. (See CLUTCH PEDAL POSITION (CPP) SWITCH INSPECTION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Is there any malfunction?	Yes	Replace the CPP switch, then go to Step 11. (See CLUTCH PEDAL POSITION SWITCH REMOVAL/INSTALLATION [C66M-R] .)
5		No	Go to the next step.
6	INSPECT CPP SWITCH GROUND CIRCUIT FOR OPEN CIRCUIT Verify that the CPP switch connector is disconnected. Inspect for continuity between CPP switch terminal B (wiring harness-side) and body ground. Is there continuity?	Yes	Go to the next step.
6		No	Refer to the wiring diagram and verify whether or not there is a common connector between CPP switch terminal B and body ground. If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit. Repair or replace the malfunctioning part. If there is no common connector: Inspect for the following: Open circuit between CPP switch and body ground Loose or lifting ground point Repair or replace the malfunctioning part. Go to Step 11.
7	INSPECT CPP SWITCH SIGNAL CIRCUIT FOR SHORT TO GROUND Verify that the CPP switch connector is disconnected. Inspect for continuity between CPP switch terminal A (wiring harness-side) and body ground. Is there continuity?	Yes	If the short to ground circuit could be detected in the wiring harness: Refer to the wiring diagram and verify whether or not there is a common connector between CPP switch terminal A and PCM terminal 2J. If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for a short to ground. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has a short to ground. If the short to ground circuit could not be detected in the wiring harness: Replace the PCM (short to ground in the PCM internal circuit). (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Go to Step 11.
7		No	Go to the next step.
8	INSPECT PCM CONNECTOR CONDITION Disconnect the PCM connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Is there any malfunction?	Yes	Repair or replace the connector and/or terminals, then go to Step 11.
8		No	Go to the next step.
9	INSPECT CPP SWITCH SIGNAL CIRCUIT FOR OPEN CIRCUIT Verify that the CPP switch and PCM connectors are disconnected. Inspect for continuity between CPP switch terminal A (wiring harness-side) and PCM terminal 2J (wiring harness-side). Is there continuity?	Yes	Go to the next step.
9		No	Refer to the wiring diagram and verify whether or not there is a common connector between CPP switch terminal A and PCM terminal 2J. If there is a common connector: Determine the malfunctioning part by inspecting the common connector and the terminal for corrosion, damage, or pin disconnection, and the common wiring harness for an open circuit. Repair or replace the malfunctioning part. If there is no common connector: Repair or replace the wiring harness which has an open circuit. Go to Step 11.
10	VERIFY THAT THERE IS NO PROBLEM WITH CUSTOMER CLUTCH PEDAL OPERATION Is the clutch pedal depressed after operating the shift lever during a traffic jam?	Yes	Explain to the customer that it is necessary to remove the foot from the clutch pedal completely after operating the shift lever. Go to the next step.
10		No	Go to the next step.
11	VERIFY DTC TROUBLESHOOTING COMPLETED Always reconnect all disconnected connectors. Clear the DTC from the PCM memory using the M-MDS. (See AFTER REPAIR PROCEDURE [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Operate the clutch pedal while driving the vehicle above 30 km/h {19 mph} and stopping 8 times alternately. Perform the Pending Trouble Code Access Procedure. (See ON-BOARD DIAGNOSTIC TEST [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Is the PENDING CODE for this DTC present?	Yes	Repeat the inspection from Step 1. If the malfunction recurs, replace the PCM. (See PCM REMOVAL/INSTALLATION [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Go to the next step.
11		No	Go to the next step.
12	VERIFY AFTER REPAIR PROCEDURE Perform the "AFTER REPAIR PROCEDURE". (See AFTER REPAIR PROCEDURE [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SKYACTIV-G 2.0, SKYACTIV-G 2.5] .)
12		No	DTC troubleshooting completed.
