DTC P0708 | Steering shift switch circuit malfunction (open circuit/short to ground)
--- | ---
DETECTION CONDITION | • Signal from steering shift switch is 0.5 V or less, or 4.7 V or more for 10 s or more. Diagnostic support note: • This is a continuous monitor (CCM). • AT warning light illuminates if TCM detects the above malfunction condition during the first drive cycle. • PENDING CODE is not available. • FREEZE FRAME DATA is available. • MIL does not illuminate. • DTC is stored in the TCM memory.
POSSIBLE CAUSE | • Steering shift switch malfunction • Open circuit in wiring harness between steering shift switch terminal 2F and TCM terminal 1W • Short to ground in wiring harness between steering shift switch terminal 2F and TCM terminal 1W • Open circuit in wiring harness between steering shift switch terminal 2C and ground • Damaged connector between steering shift switch and TCM • Clock spring malfunction • TCM malfunction

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.
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.
No | Go to the next step.
3 | INSPECT CLOCK SPRING CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • Disconnect the clock spring connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are the connector and terminals normal? | Yes | Go to the next step.
No | Repair or replace the connector and/or terminal, then go to Step 10.
4 | INSPECT CLOCK SPRING GROUND CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between the clock spring (wiring harness-side) terminal 5C and body ground. • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness, then go to Step 10.
5 | INSPECT STEERING SHIFT SWITCH • Inspect the steering shift switch. (See STEERING SHIFT SWITCH INSPECTION.) • Is the steering shift switch normal? | Yes | Go to the next step.
No | Replace the steering shift switch, then go to Step 10. (See AUDIO CONTROL SWITCH REMOVAL/INSTALLATION.)
6 | INSPECT CLOCK SPRING • Inspect the clock spring. (See CLOCK SPRING INSPECTION.) • Is the clock spring normal? | Yes | Go to the next step.
No | Replace the clock spring, then go to Step 10. (See CLOCK SPRING REMOVAL/INSTALLATION.)
7 | INSPECT TCM CONNECTOR FOR POOR CONNECTION • Disconnect the TCM connector. • Inspect for poor connection (such as damaged/pulled-out pins, corrosion). • Are the connector and terminals normal? | Yes | Go to the next step.
No | Repair or replace the connector and/or terminal, then go to Step 10.
8 | INSPECT SHIFT CONTROL SIGNAL CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between the clock spring (wiring harness-side) terminal 5F and TCM (wiring harness-side) terminal 1W. • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness, then go to Step 10.
9 | INSPECT SHIFT CONTROL SIGNAL CIRCUIT FOR SHORT TO GROUND • Inspect for continuity between the clock spring (wiring harness-side) terminal 5F and body ground. • Is there continuity? | Yes | Repair or replace the wiring harness, then go to Step 10.
No | Go to the next step.
10 | VERIFY TROUBLESHOOTING OF DTC P0708 COMPLETED • Make sure to reconnect all disconnected connectors. • Clear the DTC from the TCM memory using the WDS or equivalent. • Drive the vehicle in M range, and change gears by operating the steering shift switch. • Is the same DTC present? | Yes | Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION.)
No | Go to the next step.
11 | VERIFY AFTER REPAIR PROCEDURE • Perform the "After Repair Procedure". (See AFTER REPAIR PROCEDURE [RC4A-EL].) • Are any DTCs present? | Yes | Go to the applicable DTC inspection. (See DTC TABLE [RC4A-EL].)
No | DTC troubleshooting completed.
