SYMPTOM
ORC RUN ONLY DRIVER OVER TEMP

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

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.

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