DTC P0713 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.
1		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 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	VERIFY CURRENT INPUT SIGNAL STATUS: IS CONCERN INTERMITTENT OR CONSTANT? Turn the ignition switch to the ON position (engine off). Inspect the voltage at TCM (wiring harness-side) terminal 2J. Is the terminal voltage within 0.2-4.9 V ?	Yes	Go to the intermittent concern troubleshooting procedure, then go to Step 13. (See INTERMITTENT CONCERN TROUBLESHOOTING .)
3		No	Go to the next step.
4	INSPECT TCM CONNECTOR FOR POOR CONNECTION Turn the ignition switch to the LOCK position. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Are the connector and terminals normal?	Yes	Go to the next step.
4		No	Repair or replace the connector and/or terminal, then go to Step 13.
5	INSPECT AT SOLENOID VALVE CONNECTOR FOR POOR CONNECTION Disconnect the AT solenoid valve connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Are the connector and terminals normal?	Yes	Go to the next step.
5		No	Repair or replace the connector and/or terminal, then go to Step 13.
6	INSPECT AT SOLENOID VALVE CONNECTOR CIRCUIT FOR OPEN CIRCUIT OR SHORT TO POWER SUPPLY Turn the ignition switch to the ON position (engine off). Inspect the voltage at the AT solenoid valve connector (wiring harness-side) terminal C. Is the terminal voltage within 4.0-5.0 V ?	Yes	Go to the next step.
6		No	Repair or replace the wiring harness, then go to Step 13.
7	INSPECT AT SOLENOID VALVE CONNECTOR CIRCUIT FOR SHORT TO POWER SUPPLY Inspect the voltage at the AT solenoid valve connector (wiring harness-side) terminal D. Is the terminal voltage B+ ?	Yes	Repair or replace the wiring harness, then go to Step 13.
7		No	Go to the next step.
8	INSPECT AT SOLENOID VALVE CONNECTOR CIRCUIT FOR OPEN CIRCUIT Turn the ignition switch to the LOCK position. Disconnect the TCM connector. Inspect for continuity between the AT solenoid valve connector (wiring harness-side) terminal D and TCM (wiring harness-side) terminal 2N. Is there continuity?	Yes	Go to the next step.
8		No	Repair or replace the wiring harness, then go to Step 13.
9	INSPECT CONTROL VALVE BODY CONNECTOR FOR POOR CONNECTION Disconnect the control valve body connector. Inspect for poor connection (such as damaged/pulled-out pins, corrosion). Are the connector and terminals normal?	Yes	Go to the next step.
9		No	Repair or replace the connector and/or terminal, then go to Step 13.
10	INSPECT CONTROL VALVE BODY CONNECTOR CIRCUIT FOR SHORT TO POWER SUPPLY Turn the ignition switch to the ON position (engine off). Inspect the voltage at control valve body (wiring harness-side) terminals B and D. Is the terminal voltage B+ ?	Yes	Repair or replace the wiring harness, then go to Step 13.
10		No	Go to the next step.
11	INSPECT CONTROL VALVE BODY CONNECTOR CIRCUIT FOR OPEN CIRCUIT Turn the ignition switch to the LOCK position. Disconnect the control valve body connector. Inspect for continuity between the AT solenoid valve connector (wiring harness-side) and control valve body connector (wiring harness-side). Terminal C and terminal D Terminal D and terminal B Is there continuity?	Yes	Go to the next step.
11		No	Repair or replace the wiring harness, then go to Step 13.
12	INSPECT TFT SENSOR Inspect the TFT sensor. (See TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR INSPECTION .) Is the TFT sensor normal?	Yes	Go to the next step.
12		No	Replace the TFT sensor, then go to the next step. (See TRANSMISSION FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION .)
13	VERIFY TROUBLESHOOTING OF DTC P0713 COMPLETED Make sure to reconnect all disconnected connectors. Clear the DTC from the TCM memory using the WDS or equivalent. Drive the vehicle for 150 s or more . Is the same DTC present?	Yes	Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION .)
13		No	Go to the next step.
14	VERIFY AFTER REPAIR PROCEDURE Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE .) Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE .)
14		No	DTC troubleshooting completed.
