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 Check for related Service Bulletins and/or online repair information availability. Is any related repair information available?	Yes	Perform repair or diagnosis according to the available repair information. If 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 ignition switch to OFF. Connect voltmeter to TCM terminal 1F Turn ignition switch to ON (engine OFF). Are TCM terminal voltage within 0.2-4.9 V?	Yes	Go to intermittent concern troubleshooting procedure. (See INTERMITTENT CONCERN TROUBLESHOOTING .)
3		No	Go to the next step.
4	INSPECT TERMINAL COMPONENT NO. 2 (8-PIN) FOR POOR CONNECTION Turn ignition switch to OFF. Inspect terminal component No. 2 (8-pin) connection. Disconnect the terminal component No. 2 (8-pin). Check for poor connection (damaged, pulled-out terminals, corrosion etc.). Are connector and terminals okay?	Yes	Go to the next step.
4		No	Repair or replace the connector and/or terminal, then go to Step 11.
5	INSPECT TFT SENSOR CIRCUIT Connect voltmeter to TCM terminal 1F. Turn ignition switch to ON (engine OFF). Connect between terminal component No. 2 (8-pin) terminal H and G (harness-side) using jumper wire. Verify if TCM terminal voltage changes to 0.2 V or below . Does TCM terminal voltage change?	Yes	Go to the next step.
5		No	Go to Step 8.
6	INSPECT COUPLER COMPONENT CONNECTOR CONNECTION FOR POOR CONNECTION Turn ignition switch to OFF. Remove control valve body cover. Disconnect the coupler component connector. Check for poor connection (damaged, pulled-out terminals, corrosion, etc.). Are terminals okay?	Yes	Go to the next step.
6		No	Repair or replace the connector and/or terminal, then go to Step 11.
7	INSPECT COUPLER COMPONENT CIRCUIT FOR OPEN CIRCUIT Check continuity between coupler component (8-pin) terminals I and J (part-side). Is there continuity?	Yes	Repair or replace the terminal component No. 2 (8-pin)
7		No	Replace the TFT sensor, then go to Step 11. (See TRANSAXLE FLUID TEMPERATURE (TFT) SENSOR REMOVAL/INSTALLATION )
8	INSPECT TCM CONNECTOR FOR POOR CONNECTION Turn ignition switch to OFF. Disconnect the TCM connector. Check for poor connection (damaged, pulled-out terminals, corrosion, etc.). Are terminals okay?	Yes	Go to the next step.
8		No	Repair the terminals, then go to Step 11.
9	INSPECT HARNESS FOR OPEN CIRCUIT Disconnect the terminal component No. 2 (8-pin) Connect the TCM connector. Turn ignition switch to ON (engine OFF). Inspect voltage at terminal component No. 2 (8-pin) terminal G (harness-side). Is voltage 5 V?	Yes	Go to the next step.
9		No	Repair or replace the harness, then go to Step 11.
10	INSPECT TERMINAL COMPONENT NO. 2 (8-PIN) CIRCUIT FOR OPEN CIRCUIT Turn ignition switch to OFF. Check continuity between terminal component No. 2 (8-pin) terminal H (harness-side) and body ground. Is there continuity?	Yes	Go to the next step.
10		No	Repair or replace the harness, then go to the next step.
11	VERIFY TROUBLESHOOTING OF DTC P0713 COMPLETED Make sure to reconnect all disconnected connectors. Clear DTC from memory using WDS or equivalent. Drive vehicle for 150 s or more. Is same DTC present?	Yes	Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION .)
11		No	Go to the next step.
12	VERIFY AFTER REPAIR PROCEDURE Perform "After Repair Procedure". (See AFTER REPAIR PROCEDURE .) Is there any DTC present?
12		No	Troubleshooting completed.
