BHE050201026W08

DTC P0707 | M range switch, up switch or down switch circuit malfunction (open circuit/short to ground)
--- | ---
DETECTION CONDITION | M range switch circuit malfunction • M range switch off with up or down switch on. • M range switch remains on for 10 s or more except in D range. Up switch or down switch circuit malfunction • When all of the following conditions are met: – M range switch off. – Except D range – Up or down switch remains on for 10 s or more. Diagnostic support note: • This is a continuous monitor (CCM). • AT warning light illuminates if TCM detects the above malfunction conditions 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 | • M range switch malfunction • Up switch malfunction • Down switch malfunction. • Open circuit in wiring harness between selector lever terminal B and TCM terminal 1E • Short to ground in wiring harness between selector lever terminal B and TCM terminal 1E • Open circuit in wiring harness between selector lever terminal D and TCM terminal 2I • Short to ground in wiring harness between selector lever terminal D and TCM terminal 2I • Open circuit in wiring harness between selector lever terminal F and TCM terminal 2D • Short to ground in wiring harness between selector lever terminal F and TCM terminal 2D • Open circuit in wiring harness between selector lever terminal A and ground • Damaged connector between selector lever and TCM • 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 SELECTOR LEVER CONNECTOR FOR POOR CONNECTION • Turn the ignition switch to the LOCK position. • Disconnect the selector lever 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 9.
4 | INSPECT SELECTOR LEVER GROUND CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between the selector lever (wiring harness-side) terminal A and body ground. • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness, then go to Step 9.
5 | INSPECT M RANGE SWITCH, UP SWITCH, AND DOWN SWITCH • Inspect the M range switch, up switch, and down switch. (See SELECTOR LEVER INSPECTION) • Are the switches normal? | Yes | Go to the next step.
No | Replace the selector lever, then go to Step 9. (See SELECTOR LEVER REMOVAL/INSTALLATION.)
6 | 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 9.
7 | INSPECT SELECTOR LEVER SIGNAL CIRCUIT FOR OPEN CIRCUIT • Inspect for continuity between the selector lever (wiring harness-side) and TCM (wiring harness-side). – M range switch position: terminal B and terminal 1E – Up switch position: terminal D and terminal 2I – Down switch position: terminal F and terminal 2D • Is there continuity? | Yes | Go to the next step.
No | Repair or replace the wiring harness, then go to Step 9.
8 | INSPECT SELECTOR LEVER SIGNAL CIRCUIT FOR SHORT TO GROUND • Inspect for continuity between the selector lever (wiring harness-side) and body ground. – M range switch position: terminal B and body ground – Up switch position: terminal D and body ground – Down switch position: terminal F and body ground • Is there continuity? | Yes | Repair or replace the wiring harness, then go to Step 9.
No | Go to the next step.
9 | VERIFY TROUBLESHOOTING OF DTC P0707 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 shifting the selector lever (operating the up and down switches). • Is the same DTC present? | Yes | Replace the TCM, then go to the next step. (See TCM REMOVAL/INSTALLATION.)
No | No concern is detected. Go to the next step.
10 | 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.
