•  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 STEERING SHIFT SWITCH
•  Inspect the steering shift switch.
•  Is the steering shift switch normal?
Yes
Go to the next step.
No
Replace the steering shift switch, then go to Step 9.
(See AUDIO CONTROL SWITCH REMOVAL/INSTALLATION.)
5
INSPECT CLOCK SPRING
•  Inspect the clock spring.
•  Is the clock spring normal?
Yes
Go to the next step.
No
Replace the clock spring, then go to Step 9.
(See CLOCK SPRING REMOVAL/INSTALLATION.)
6
INSPECT TCM CONNECTOR FOR POOR CONNECTION
•  Disconnect the TCM connector.
•  Inspect for poor connection at TCM terminals 2AF and 2AB (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 SIGNAL CIRCUIT FOR OPEN CIRCUIT
•  Inspect for continuity between the clock spring (wiring harness-side) terminal 4F and TCM (wiring harness-side) terminal 2AF.
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to Step 9.
8
INSPECT GROUND CIRCUIT FOR OPEN CIRCUIT
•  Inspect for continuity between the clock spring (wiring harness-side) terminal 4C and TCM (wiring harness-side) terminal 2AB.
•  Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to Step 9.
9
VERIFY TROUBLESHOOTING OF DTC P0826 COMPLETED
•  Make sure to reconnect all 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.  Idle the engine 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.
