Yes
Go to the next step.
No
Inspect the TCM 15 A fuse.
•  If the fuse is blown:
―  Repair or replace the wiring harness for a possible short to ground.
―  Replace the malfunctioning fuse.
•  If the fuse is deteriorated:
―  Replace the malfunctioning fuse.
•  If the fuse is normal:
―  Repair or replace the wiring harness for a possible open circuit.
Go to the next step.
