FCM ORC Run Only Driver Over Current (Active)

Tests 1 - 2:

Tests 3 - 6:

Test 7:

SYMPTOM
FCM, ORC RUN ONLY DRIVER OVER CURRENT - ACTIVE

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

WHEN MONITORED
The FCM uses a microprocessor controlled transistor (high side driver) to supply power to the ORC. The microprocessor monitors the high side driver (HSD) internal temperature when the ignition is in the Run Only position.

SET CONDITION
The code will set within 1 second, if the microprocessor senses HSD internal temperature. The high temperature is caused by over current.

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
