Is the status Active for this DTC?

Yes
1. Go To 2).
No
1. Refer to the *CHECKING FOR AN INTERMITTENT CONDITION Diagnostic Procedure.
2) VISUAL AND PHYSICAL CONNECTOR AND TERMINAL INSPECTION
NOTE: Ensure the Starter is bolted securely and is properly mounted.

Turn the ignition off.

Disconnect the TIPM C10 harness connector.

Disconnect the Starter (1-way) harness connector.

Inspect the terminal and connector condition. Check for signs of corrosion build up or damage that would compromise the terminal to controller pin connector.

NOTE: Make sure that all in-line connectors are inspected for corrosion and/or damage.

Visually inspect the wiring harness. Look for any chafed, pierced, pinched or partially broken wires hidden in the wire insulation.

Were any of the above conditions found?

Yes
1. Repair or replace as necessary.
2. Perform PCM VERIFICATION TEST .
No
1. Go To 3).

Turn the ignition off.

Reconnect the TIPM C10 harness connector.

With a 12-volt test light connected to ground, probe the (T750) Starter Control Output circuit in the Starter (1-way) harness connector

WARNING: When the engine is operating, do not stand in direct line with the fan. Do not put your hands near the pulleys, belts, or fan. Do not wear loose clothing. Failure to follow these instructions can result in personal injury or death.

Yes
1. Replace the Starter in accordance with the Service Information.
2. Perform PCM VERIFICATION TEST .
No
1. Go To 4).

Turn the ignition off.

Disconnect the TIPM C10 harness connector.

With a jumper wire, connect one end to the (T750) Starter Control Output circuit in the Starter harness connector and the other to a clean chassis ground.

Using a 12-volt test light to battery voltage, probe the (T750) Starter Control Output circuit in the TIPM C7 harness connector.

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

Does the test light illuminate brightly.

Yes
1. Go To 5).
No
1. Repair the high resistance in the (T750) Starter Control Output circuit.
2. Perform PCM VERIFICATION TEST .
5) TOTALLY INTEGRATED POWER MODULE
NOTE: Before continuing, check the TIPM harness connector terminals for corrosion, damage, or terminal push out. Repair as necessary.

Using the schematics as a guide, inspect the wire harness and connectors.

Pay particular attention to all Power and Ground circuits.

Were any problems found?

Yes
1. Repair as necessary.
2. Perform PCM VERIFICATION TEST .
No
1. Replace the Totally Integrated Power Module per Service Information.
2. Perform PCM VERIFICATION TEST .
