•  TCM malfunction

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.
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.
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 GND
•  Inspect for continuity between selector lever component terminals (wiring harness-side) and body GND.
―  Terminal B and body GND (M range switch)
―  Terminal D and body GND (up switch)
―  Terminal F and body GND (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.
(See SELECTOR LEVER REMOVAL/INSTALLATION.)
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 GND.
•  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 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.  Drive the vehicle in M range, and shift the selector lever (operate up and down switches) between 1GR to 6GR for 10 s or more.
•  Is the same DTC present?
Yes
Replace the TCM, then go to the next step.
(See TCM REMOVAL/INSTALLATION [SJ6A-EL].)
No
Go to the next step.
10
VERIFY NO DTC HAS BEEN PRESENTED
•  Perform the “Reading DTCs Procedure”.
•  Are any DTCs present?
Yes
Go to the applicable DTC inspection.
(See DTC TABLE [SJ6A-EL].)
No
DTC troubleshooting completed.
