No
Go to the next step.
6
INSPECT POWER CIRCUIT FOR SHORT TO GND
•  Turn the ignition switch to the LOCK position.
•  Disconnect both battery cables.
•  Disconnect the TCM connector.
•  Inspect for continuity between the following circuits:
―  TCM terminal A11 (wiring harness-side) and body GND
―  TCM terminal A1 (wiring harness-side) and body GND
•  Is there continuity?
Yes
Repair or replace the wiring harness for a possible short to GND, then go to Step 9.
No
Go to the next step.
7
INSPECT POWER CIRCUIT FOR OPEN CIRCUIT
•  Turn the ignition switch to the LOCK position.
