SYMPTOM
MODE CALIBRATION FAULT

TEST NOTE
This symptom is diagnosed using the test BLEND CALIBRATION FAULT.

WHEN MONITORED
When the HVAC Door Recalibration is executed.

SET CONDITION
If the 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.
