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

• Is there continuity?
Yes
Go to the next step.
No
Repair or replace the wiring harness, then go to Step 10.
5

INSPECT STEERING SHIFT SWITCH

• Inspect the steering shift switch.

Yes
Go to the next step.
No
Replace the clock spring, then go to Step 10.
7
INSPECT TCM CONNECTOR FOR POOR CONNECTION
• Disconnect the TCM connector.
• Inspect for poor connection at TCM terminals 2AB and 2AF (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 10.
8
INSPECT SHIFT CONTROL SIGNAL CIRCUIT FOR OPEN CIRCUIT
• Inspect for continuity between the clock spring (wiring harness-side) terminal 5F 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 10.
9
