Diagnostic Test

1. MECHANICAL CONDITION

NOTE: Check and diagnose all the TIPM DTC(s) before continuing.

NOTE: Ensure the Gear selector is in Park or Neutral.

NOTE: Verify the battery is fully charged and capable of passing a load test before continuing.

WARNING: Make sure the battery is disconnected, then wait two minutes before proceeding. Failure to do so may result in personal injury or possible death.

Turn the engine over by hand to make sure the engine is not seized.

Is the engine able to turn over?

Yes

- Go to 2

No

- Repair the mechanical condition preventing the starter motor from cranking.
- Perform the POWERTRAIN VERIFICATION TEST. PCM Verification Test
