ZONE CALIBRATION FAULT
When Monitored:
When the HVAC Door Recalibration is executed.
Set Condition:
If the driver blend (dual-zone) door’s span is found outside the tolerance
due to: open door actuator electrical circuits; a bad door actuator; broken door linkage; a
bound up door; door actuator electrical circuits shorted to voltage; door actuator electrical
circuits shorted to ground. A short to voltage or ground on the door actuator electrical
circuits will also set door actuator overcurrent faults.
