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.
• Are the switches normal?
Yes
Go to the next step.
No
Replace the selector lever, then go to Step 9.
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.

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.
No
No concern is detected. Go to the next step.
