Connect the Powertrain Control Module (PCM) connector.

Turn the ignition on.

Using a 12 volt test light connected to 12 volts, check the (T752) Starter Control circuit in the Totally Integrated Power Module (TIPM) harness connector.

NOTE: The test light should not be illuminated.

While monitoring the test light, move the ignition to the start position.

NOTE: The test light should be illuminated and bright. Compare the brightness to that of a direct connection to the battery.

Is the test light not illuminated with the ignition in the run position and illuminated and bright with the ignition in the start position?

Yes
1. Replace the Totally Integrated Power Module (TIPM) in accordance with the Service Information.
2. Perform PCM VERIFICATION TEST .
No
1. Go to 5).
5) POWERTRAIN CONTROL MODULE (PCM)
Using the wiring diagram/schematic as a guide, inspect the wiring and connectors between the Totally Integrated Power Module (TIPM) and the Powertrain Control Module (PCM).

Look for any chafed, pierced, pinched, or partially broken wires.

Look for broken, bent, pushed out or corroded terminals.

Refer to any Technical Service Bulletins that may apply.

Were any problems found?

Yes
1. Repair as necessary.
2. Perform PCM VERIFICATION TEST .
No
1. Replace and program the Powertrain Control Module (PCM) in accordance with the Service Information.
2. Perform PCM VERIFICATION TEST .
