Diagnostic procedure

STEP	INSPECTION		ACTION
1	VERIFY FREEZE FRAME DATA HAS BEEN RECORDED • Has the FREEZE FRAME DATA been recorded on the repair order?	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 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 TR SWITCH CIRCUIT • Connect the TCM connector. • Turn the ignition switch to the ON position. (engine off) • Inspect the voltage between TCM terminal (wiring harness-side) and body GND. ― TCM terminal 2O • P position: B+ • Other positions and all ranges: 0V ― TCM terminal 2M • R position: B+ • Other position and all ranges: 0V ― TCM terminal 2N • N position: B+ • Other position and all range: 0V ― TCM terminal 2K • D range: B+ • Other ranges and all positions: 0V • Are any of following terminal voltage turned on for even a moment while shifting selector lever slowly from P position to D range?	Yes	Go to Step 13.
3		No	Go to the next step.
4	INSPECT TR SWITCH CIRCUIT • Are all terminal voltage 0 V in Step 3?	Yes	Go to Step 10.
4		No	Go to the next step.
5	INSPECT TR SWITCH CIRCUIT • Are there two or more terminals where the voltage is abnormal in Step 3?	Yes	Adjust the TR switch, then go to Step 13. (See TRANSMISSION RANGE (TR) SWITCH ADJUSTMENT [SJ6A-EL].)
5		No	Go to the next step.
6	INSPECT TCM CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • Disconnect the TCM connector. • Inspect for poor connection at TCM terminals 2O, 2K, 2M and 2N (such as damaged/pulled-out pins, corrosion). • Is there any malfunction?	Yes	Repair or replace the connector and/or terminal, then go to Step 13.
6		No	Go to the next step.
7	INSPECT TR SWITCH SIGNAL CIRCUIT FOR SHORT TO GND • Inspect for continuity between TR switch terminals (wiring harness-side) and body GND. ― P position: B and body GND ― R position: C and body GND ― N position: H and body GND ― D range: D and body GND • Is there continuity?	Yes	Repair or replace the wiring harness for short to GND, go to Step 12.
7		No	Go to the next step.
8	INSPECT TR SWITCH CONNECTOR FOR POOR CONNECTION • Disconnect the TR switch connector. • Inspect for poor connection at TR switch terminals B, C, D and H (part-side) (such as damaged/pulled-out pins, corrosion) • Are TR switch terminals normal?	Yes	Go to the next step.
8		No	Repair terminals or replace the TR switch, then go to Step 13. (See TRANSMISSION RANGE (TR) SWITCH REMOVAL/INSTALLATION [SJ6A-EL].)
9	INSPECT TR SWITCH • Inspect the TR switch. (See TRANSMISSION RANGE (TR) SWITCH INSPECTION [SJ6A-EL].) • Is the TR switch normal?	Yes	Repair or replace the wiring harness for open circuit, then go to Step 13.
9		No	Replace the TR switch, then go to Step 13. (See TRANSMISSION RANGE (TR) SWITCH REMOVAL/INSTALLATION [SJ6A-EL].)
10	INSPECT TR SWITCH POWER CIRCUIT FOR OPEN CIRCUIT • Turn the ignition switch to the LOCK position. • Disconnect the TR switch connector. • Turn the ignition switch to the ON position (engine off). • Inspect the voltage at TR switch (wiring harness-side) terminal E. • Is there B+ at TR switch (wiring harness-side) terminal E?	Yes	Go to the next step.
10		No	Inspect the METER 15 A fuse. • If normal, repair or replace the wiring harness, then go to Step 13.
11	INSPECT TR SWITCH CONNECTOR FOR POOR CONNECTION • Disconnect the TR switch connector. • Inspect for poor connection at TR switch terminal E (part-side) (such as damaged/pulled-out pins, corrosion) • Are TR switch terminals normal?	Yes	Go to the next step.
11		No	Repair terminals or replace the TR switch, then go to Step 13. (See TRANSMISSION RANGE (TR) SWITCH REMOVAL/INSTALLATION [SJ6A-EL].)
12	INSPECT TR SWITCH • Inspect the TR switch. (See TRANSMISSION RANGE (TR) SWITCH INSPECTION [SJ6A-EL].) • Is the TR switch normal?	Yes	Go to the next step.
12		No	Replace the TR switch, then go to the next step. (See TRANSMISSION RANGE (TR) SWITCH REMOVAL/INSTALLATION [SJ6A-EL].)
13	VERIFY TROUBLESHOOTING OF DTC P0708 COMPLETED • Make sure to reconnect all the disconnected connectors. • Clear the DTC using the M-MDS. • Perform the following procedure to ensure that the DTC has been resolved: 1. Start the engine. 2. Warm-up the engine to normal operating temperature. 3. Depress the brake pedal, and shift the selector lever from P to D for 2 s or more. 4. Turn the ignition switch to the LOCK position. 5. Start the engine. 6. Depress the brake pedal, and shift the selector lever from P to D for 2 s or more. • Is the PENDING CODE same as the DTC present?	Yes	Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION [SJ6A-EL].)
13		No	Go to the next step.
14	VERIFY NO DTC HAS BEEN PRESENTED • Perform the “Reading DTCs Procedure”. (See AUTOMATIC TRANSMISSION ON-BOARD DIAGNOSTIC FUNCTION [SJ6A-EL].) • Are any DTCs present?	Yes	Go to the applicable DTC inspection. (See DTC TABLE [SJ6A-EL].)
14		No	DTC troubleshooting completed.
