Blend Calibration Fault - Mtc; Mode Calibration Fault - Mtc; Rear Blend Calibration Fault - Mtc; Rear Mode Calibration Fault - Mtc - Chrysler Town and Country 2003 Owner's Manual

Symptom List:

BLEND CALIBRATION FAULT - MTC

MODE CALIBRATION FAULT - MTC

REAR BLEND CALIBRATION FAULT - MTC

REAR MODE CALIBRATION FAULT - MTC

RECIRCULATION CALIBRATION FAULT - MTC

ZONE CALIBRATION FAULT - MTC

Test Note: All symptoms listed above are diagnosed using the same tests.
The title for the tests will be BLEND CALIBRATION FAULT -
MTC.
When Monitored and Set Condition:
BLEND CALIBRATION FAULT - MTC
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.
MODE CALIBRATION FAULT - MTC
When Monitored: When the HVAC Door Recalibration is executed.
Set Condition: If the mode 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.
REAR BLEND CALIBRATION FAULT - MTC
When Monitored: When the HVAC Door Recalibration is executed.
Set Condition: If the rear 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.
REAR MODE CALIBRATION FAULT - MTC
When Monitored: When the HVAC Door Recalibration is executed.
Set Condition: If the rear mode 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.
