    Using a 12 volt test light connected to 12 volts, probe the (F200) Fused Ignition Switch Output (Run-Start) Circuit in the TIPM C7 harness connector.

    Does the test light illuminate brightly? 

    Yes 

    1. Go to  4).

    No 

    1. Repair the Fused Ignition Switch Output (Run-Start) Circuit for high resistance.

    Reconnect the TIPM C7 harness connector.

    Turn the ignition on.

    Using a 12 volt test light connected to ground, probe the (F200) Fused Ignition Switch Output (Run-Start) circuit in the 8443-24 Load Tool ORC Adapter.

    Does the test light illuminate brightly? 

    Yes 

    1. Replace the ORC in accordance with the service information.
    2. Perform BODY VERIFICATION TEST - VER 1 .
