Blend Calibration Fault

Test 1 - 2:

Tests 3 - 6:

SYMPTOM
BLEND CALIBRATION FAULT

WHEN MONITORED
When the HVAC Door Recalibration is executed.

SET CONDITION
If the passenger blend 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.

POSSIBLE CAUSES
- Check for actuator circuit test fault messages
- Check for HVAC DTCs
- Door actuator driver circuit open
- Common door driver circuit open
- Door actuator
- Door actuator/Linkage/Door
- A/C-heater control module
