FCM ORC Run/Start Driver Open (Active)

SYMPTOM
FCM, ORC RUN-START 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 Only 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-start driver codes
- Check battery voltage
- FCM, run-start driver over voltage
- ORC, run-start test
- FCM, run only open test
- IPM, run only open test
- ORC run only driver circuit open
- FCM, run-start short test
- IPM, run-start short test
- ORC run-start driver circuit short
