- (F200) Fused ignition switch output (run-start) circuit short to ground
- ORC internal short
- TIPM
Diagnostic Test
1. CHECK FOR ACTIVE DTC
With the scan tool, read the active DTC's.
Cycle the ignition switch from off to on, leaving the ignition on for a minimum of 10 seconds.
With the scan tool, read the active DTC's.

3. (F200) FUSED IGNITION SWITCH OUTPUT (RUN-START) CIRCUIT SHORT TO GROUND
Turn the ignition off.
Disconnect the TIPM C7 harness connector.
Measure the resistance between ground and the (F200) Fused Ignition Switch Output (Run-Start) circuit.
Q: Is the resistance below 10K ohms?
YES: Repair the (F200) Fused Ignition Switch Output (Run-Start) circuit for a short to ground. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
NO: Repair the TIPM. Perform the BODY VERIFICATION TEST - VER 1. Body Verification Test
