DTC P0705 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 LOCK position. Disconnect the TCM connector. Turn the ignition switch to the ON position (engine off). Inspect each TCM (wiring harness-side) terminal voltage. (See TCM INSPECTION .) 1D P position: B+ Other positions and all ranges: 0 V 2C R position: B+ Other positions and all ranges: 0 V 2B N position: B+ Other positions and all ranges: 0 V 2E D range: B+ Other ranges and all positions: 0 V Are two or more of the above terminal voltage measurements indicated at the same time when shifting selector lever from P position to D range?	Yes	Go to the next step.
3		No	Turn the ignition switch to the LOCK position. Connect the TCM connector. Go to the intermittent concern troubleshooting procedure, then go to Step 7. (See INTERMITTENT CONCERN TROUBLESHOOTING .)
4	INSPECT TR SWITCH CONNECTOR Turn the ignition switch to the LOCK position. Disconnect the TR switch connector. Inspect for bent terminals for bending using mirror. Are the TR switch terminals normal?	Yes	Go to the next step.
4		No	Repair the terminals or replace the TR switch, then go to Step 7. (See TRANSMISSION RANGE (TR) SWITCH REMOVAL/INSTALLATION .)
5	INSPECT TR SWITCH Inspect the TR switch. (See TRANSMISSION RANGE (TR) SWITCH INSPECTION .) Is the TR switch normal?	Yes	Go to the next step.
5		No	Replace the TR switch, then go to Step 7. (See TRANSMISSION RANGE (TR) SWITCH REMOVAL/INSTALLATION .)
6	INSPECT TR SWITCH CIRCUIT FOR SHORT TO POWER SUPPLY Turn the ignition switch to the ON position (engine off). Measure the voltage at TR switch (wiring harness-side) terminals A, E, D, and G. Is there 0 V at the TR switch harness-side connector terminals?	Yes	Go to the next step.
6		No	Repair or replace the wiring harness, then go to the next step.
7	VERIFY TROUBLESHOOTING OF DTC P0705 COMPLETED Turn the ignition switch to the LOCK position. Make sure to reconnect all disconnected connectors. Clear the DTC from the TCM memory using the WDS or equivalent. Turn the ignition switch to the START position (engine on). Drive the vehicle in each range (P, R, N, and D) for 12 s or more . Is the same DTC present?	Yes	Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION .)
7		No	Go to the next step.
8	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 .)
8		No	DTC troubleshooting completed.
