Also inspect the related connectors for broken, bent, pushed out, spread, corroded, or contaminated terminals.
- Perform the BODY VERIFICATION TEST. Body Verification Test

2. CHECK THE (F20) IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT FOR A SHORT TO BATTERY VOLTAGE


1. Turn the ignition off.

2. Disconnect the TIPM C7 harness connector.

3. Cycle the ignition on and off.

4. Using a 12-volt test light connected to ground, check the (F20) Ignition Switch Output (Run-Start) circuit at the TIPM C7 harness connector.

Does the test light illuminate brightly?

Yes

- Repair the (F20) Ignition Switch Output (Run-Start) circuit for a short to battery voltage.
- Perform the BODY VERIFICATION TEST. Body Verification Test
