• TCM malfunction

Diagnostic procedure

STEP

INSPECTION

ACTION

1
VERIFY FREEZE FRAME DATA HAS BEEN RECORDED
• Has the 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 TCM CONNECTOR FOR POOR CONNECTION
• Disconnect the TCM connector.
• Inspect for poor connection at TCM terminals 2F, 2G and 2J (such as damaged/pulled-out pins, corrosion).
• Are 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 COMPONENT CONNECTOR FOR POOR CONNECTION
• Disconnect the selector lever component connector.
• Inspect for poor connection at selector lever component terminals A, B, D and F (such as damaged/pulled-out pins, corrosion).
• Are terminals normal?
Yes
Go to the next step.
No
Repair or replace the connector and/or terminal, then go to Step 9.
5
INSPECT M RANGE SWITCH, UP SWITCH, AND DOWN SWITCH CIRCUIT FOR SHORT TO GROUND
• Inspect for continuity between selector lever component terminals (wiring harness-side) and body ground.
- Terminal B and body ground (M range switch)
- Terminal D and body ground (up switch)
- Terminal F and body ground (down switch)
• Is there continuity?
Yes
Repair or replace the harness, then go to Step 9.
No
Go to the next step.
6

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.
7
INSPECT M RANGE SWITCH, UP SWITCH, AND DOWN SWITCH CIRCUIT FOR OPEN CIRCUIT
• Inspect for continuity between selector lever component terminal A (wiring harness-side) and body ground.
• Is there continuity?
Yes
Go to the next step.
No
Repair or replace the harness, then go to Step 9.
8
INSPECT M RANGE SWITCH, UP SWITCH, AND DOWN SWITCH CIRCUIT FOR OPEN CIRCUIT
• Inspect for continuity between TCM terminals (wiring harness-side) and selector lever component terminals (wiring harness-side).
- Terminal 2G and terminal B (M range switch)
- Terminal 2J and terminal D (up switch)
- Terminal 2F and terminal F (down switch)
• Is there continuity?
Yes
Go to the next step.
No
Repair or replace the harness, then go to the next step.
9
VERIFY TROUBLESHOOTING OF DTC P0819 COMPLETED
• Make sure to reconnect all the disconnected connectors.
• Clear the DTC from the memory using the M-MDS.
• Drive the vehicle in M range, and change gears by shifting the selector lever (operating the up and down switches).
• Is same DTC present?
Yes
Replace the TCM, then go to the next step.
No
Go to the next step.
10
VERIFY AFTER REPAIR PROCEDURE
• Perform the "After Repair Procedure".
• Are any DTCs present?
Yes
Go to the applicable DTC inspection.
No
Troubleshooting completed.
