Symptom List:
BLEND DOOR OUTPUT SHORT TO GROUND - ATC & MTC
COMMON OUTPUT SHORT TO GROUND - ATC & MTC
MODE DOOR OUTPUT SHORT TO GROUND - ATC & MTC
RECIRC DOOR OUTPUT SHORT TO GROUND - ATC & MTC
Test Note:
All symptoms listed above are diagnosed using the same tests.
The title for the tests will be BLEND DOOR OUTPUT SHORT
TO GROUND - ATC & MTC.
When Monitored and Set Condition:
BLEND DOOR OUTPUT SHORT TO GROUND - ATC & MTC
When Monitored:
Whenever the BCM attempts to drive one of the HVAC actuators.
Set Condition:
This DTC will set if the BCM detects one or more of the following outputs
shorted to ground: mode door driver, blend door driver, recirculation door driver or the
common door driver.
COMMON OUTPUT SHORT TO GROUND - ATC & MTC
When Monitored:
Whenever the BCM attempts to drive one of the HVAC actuators.
Set Condition:
This DTC will set if the BCM detects one or more of the following outputs
shorted to ground: mode door driver, blend door driver, recirculation door driver or the
common door driver.
MODE DOOR OUTPUT SHORT TO GROUND - ATC & MTC
When Monitored:
Whenever the BCM attempts to drive one of the HVAC actuators.
Set Condition:
This DTC will set if the BCM detects one or more of the following outputs
shorted to ground: mode door driver, blend door driver, recirculation door driver or the
common door driver.
RECIRC DOOR OUTPUT SHORT TO GROUND - ATC & MTC
When Monitored:
Whenever the BCM attempts to drive one of the HVAC actuators.
Set Condition:
