SYMPTOM
ORC RUN - START DRIVER OPEN

TEST NOTE
This symptom is diagnosed using the test LOSS OF IGNITION RUN - START.

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
- ORC, loss of ignition run - start
- ACM, ORC run - start open
- FCM, ORC run - start open
- IPM, ORC run - start driver open
- ORC run - start driver circuit open
- FCM, ORC run - start short
- IPM, ORC run - start short
- ORC run - start circuit short
- ACM, ORC run - start driver circuit short
- High battery voltage
- FCM, run - start over voltage
- Stored code or intermittent condition
- Active code present
