ORC Run - Start Driver Shorted to Ground

Test 1 - 3:

Test 4 - 6:

Test 7 - 8:

SYMPTOM
ORC RUN - START DRIVER SHORT TO GROUND

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

WHEN MONITORED
The IPM uses a microprocessor controlled transistor (high side driver) to supply power to the ACM. The microprocessor monitors for short to ground when the ignition is in the Run or Start position.

SET CONDITION
The code will set within 1 second.

POSSIBLE CAUSES
- ORC, loss of ignition run - start
- ACM, ORC run - start circuit open
- IPM, ORC run - start circuit open
- Run - start driver circuit open
- IPM, ORC run - start short
- ORC run - start short
- ACM, ORC run - start short
- Stored code or intermittent condition
- Active code present
