FCM ORC Run Only Driver Shorted to Ground (Active)

SYMPTOM
FCM, ORC RUN ONLY DRIVER SHORT TO GROUND - ACTIVE

TEST NOTE
This symptom is diagnosed using the test FCM, ORC RUN ONLY DRIVER OPEN - ACTIVE.

WHEN MONITORED
When the ignition is turned OFF, the microprocessor controlled transistor (high side driver) places a diagnostic voltage on the ORC Run-Start circuit for 60 seconds. An open high side driver (HSD) circuit voltage is between 2.4 and 5.0 volts.

SET CONDITION
This code will set within 10 second, if the microprocessor senses 2.4 to 5.0 volts on the HSD. Note: the diagnostic voltage will only last for 60 seconds after the ignition is turned OFF.

POSSIBLE CAUSES
- Verifying ORC run only driver codes
- Check battery voltage
- FCM, run only driver over voltage
- ORC, run only open test
- FCM, run only open test
- IPM, run only open test
- ORC run only driver circuit open
- FCM, run only short test
- IPM, run only short test
- ORC run only driver circuit short
