Test Note: All symptoms listed above are diagnosed using the same tests.
The title for the tests will be FCM, ORC RUN ONLY DRIVER
OPEN - STORED.
When Monitored and Set Condition:
FCM, ORC RUN ONLY DRIVER OPEN - STORED
When Monitored: When the ignition is turned OFF, the microprocessor controlled
transistor (high side driver) places a diagnostic voltage on the ORC Run-Start 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.
FCM, ORC RUN ONLY DRIVER OVER CURRENT - STORED
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.
FCM, ORC RUN ONLY DRIVER OVER TEMP - STORED
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 position.
Set Condition: The code will set within 2.5 second, if the microprocessor senses high HSD
internal temperature. The high temperature is caused by over current.
