- When Monitored:
With the ignition on.

- Set Condition:
(F200) Fused Ignition Switch Output (Run-Start) circuit low.





Diagnostic Test

1. CHECK FOR ACTIVE DTC
Check all fuses.
With the scan tool, read the active DTC's.
Cycle the ignition switch from off to on, leaving the ignition off for a minimum of 30 seconds.
With the scan tool, read the active DTC's.
Does the scan tool display this DTC as active?

Yes

- Go to 2

No

- If the DTC is stored, check for an intermittent condition. Using the wiring diagram/schematic as a guide, visually inspect the related wiring harness connectors. Look for broken, bent, pushed out, or corroded terminals.

2. CHECK (F200) CIRCUIT FOR A SHORT TO GROUND
Turn the ignition off.
Remove fuse number 28.
Turn the ignition on.
With the scan tool, read DTCs.
Did the DTC changed from active to stored?

Yes

- Go to 3


No

- Go to 5

3. ORC INTERNAL SHORT




WARNING: To avoid personal injury or death, turn the ignition off, disconnect the battery and wait two minutes before proceeding.

Disconnect the ORC C2 harness connector.
Reinstall fuse number 28.
Turn the ignition on.
Reconnect the battery.
With the scan tool, read DTCs.
Does the scan tool display this DTC as active?

Yes

- Go to 4


No

- Replace the ORC.
- Perform BODY VERIFICATION TEST VER 1 Body Verification Test

4. (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.
Is the resistance below 10K ohms?

Yes

- Repair the (F200) Fused Ignition Switch Output (Run-Start) circuit for a short to ground.
- Perform BODY VERIFICATION TEST VER 1 Body Verification Test

No

- Repair the TIPM.
- Perform BODY VERIFICATION TEST VER 1 Body Verification Test

5. CHECK TIPM FOR AN INTERNAL SHORT




Turn the ignition off.
Disconnect the TIPM C11 harness connector.
With the scan tool, read DTCs.
Did the DTC changed from active to stored?

Yes

- Go to 6

No

- Replace the TIPM.
- Perform BODY VERIFICATION TEST VER 1 Body Verification Test

6. CHECK COMPONENT FOR AN INTERNAL SHORT
NOTE: The (F202) circuit is the power supply for multiple modules.

Turn the ignition off.
Reconnect the TIPM C11 harness connector.
Using the wiring diagrams as a guide, disconnect each component that is fed by the (F202) circuit one at a time while checking for the DTC to become stored.
With the scan tool, read DTCs.
Did the DTC changed from active to stored?

Yes

- Replace the shorted component.
- Perform BODY VERIFICATION TEST VER 1 Body Verification Test

No

- Repair the (F202) Fused Ignition Switch Output (Run-Start) circuit for a short to ground.
- Perform BODY VERIFICATION TEST VER 1 Body Verification Test
