ORC RUN ONLY DRIVER OVER VOLT 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) Set Condition: The code will set if the microprocessor senses HSD battery voltage is over 30 volts. ORC RUN ONLY DRIVER SHORT TO GROUND 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) Set Condition: The code will set within 1 second, if the microprocessor senses high HSD internal temperature. The high temperature is caused by short to ground.
