Continued
Symptom List:
BLEND DOOR OUTPUT SHORT TO BATTERY - ATC & MTC
COMMON OUTPUT SHORT TO BATTERY - ATC & MTC
MODE DOOR OUTPUT SHORT TO BATTERY - ATC & MTC
RECIRC DOOR OUTPUT SHORT TO BATTERY - 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 BATTERY - ATC & MTC.
When Monitored and Set Condition:
BLEND DOOR OUTPUT SHORT TO BATTERY - ATC & MTC
When Monitored:
Whenever the BCM attempts to drive the Blend Door Actuator.
Set Condition:
This DTC will set if the BCM detects a short to voltage on the Blend Door
Driver circuit. All Door Output Shorted To Batt DTCs may set if at least one door output
is shorted.
COMMON OUTPUT SHORT TO BATTERY - 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 a short to voltage on the Common
Door Driver circuit. All Door Output Shorted To Batt DTCs may set if at least one door
output is shorted.
MODE DOOR OUTPUT SHORT TO BATTERY - ATC & MTC
When Monitored:
Whenever the BCM attempts to drive the Mode Door Actuator.
Set Condition:
This DTC will set if the BCM detects a short to voltage on the Mode Door
Driver circuit. All Door Output Shorted To Batt DTCs may set if at least one door output
is shorted.
RECIRC DOOR OUTPUT SHORT TO BATTERY - ATC & MTC
When Monitored:
Whenever the BCM attempts to drive the Recirculation Door Actuator.
Set Condition:
This DTC will set if the BCM detects a short to voltage on the
Recirculation Door Driver circuit. All Door Output Shorted To Batt DTCs may set if at least
one door output is shorted.

1
Turn the ignition on.
With the DRBIII
t, record and erase Body Computer DTC’s.
Cycle the ignition switch.
Start the engine.
With the DRBIII
t in Miscellaneous, actuate Calibrate HVAC Door Motors.
With the DRBIII
t, read the Body Computer DTCs.
Does the DRBIII
t display: XXXX Door Output Short To Batt?
All
Yes
→ Go To 2
No
→ Go To 11
2
Turn the ignition off.
Disconnect the Body Control Module C2 harness connector.
Turn the ignition on.
Measure the voltage between ground and each of the Door Driver circuits (Blend,
Mode, Recirc, & Common).
Is the voltage above 0.2 volts?
All
Yes
→ Repair all Door Driver circuits with voltage above 0.2 volts for a
short to battery.
Calibration must be performed after repair/replacement is com-
pleted.
Perform BODY VERIFICATION TEST - VER 1.
No
→ Go To 3
3
Turn the ignition off.
Disconnect the Body Control Module C2 harness connector.
Measure the resistance between the Blend Door Driver circuit and the Mode Door
Driver circuit, and the Recirc Door Driver circuit in the BCM C2 harness connector.
Measure the resistance between the Mode Door Driver circuit and the Recirc Door
Driver circuit in the BCM C2 harness connector.
Is the resistance below 10K ohms on any of the circuits?
All
Yes
→ Repair all door driver circuits with a resistance below 10K ohms
for short together.
Calibration must be performed after repair/replacement is com-
pleted.
Perform BODY VERIFICATION TEST - VER 1.
