B10A7–LEFT BLEND DOOR TRAVEL RANGE TOO LARGE (DUAL-ZONE)
For a complete wiring diagramRefer to Section 8W.
Theory of Operation
The A/C Heater Control calibrates each actuator individually. Automaticcalibration occurs upon power up after
installing a new A/C Heater Control. Manual calibration occurs by sendinga command with the scan tool. The pur-
pose of actuator calibration is to determine the total span of door travel between physical stops. To calibrate the
actuator, the A/C Heater Control first moves the door to an end stop, and then counts the number of pulses it takes
to move the door to its other stop. An expected range of span is stored in the control’s memory. If the measured
calibration value exceeds the expected range for this actuator, this DTC will set. Note that the control clears all
stored calibration faults at the beginning of the calibration procedure.
When Monitored:
During actuator calibration.
Set Condition:
If the total span of the Left Blend Door exceeds the high range limit.

B10B2–A/C COOL DOWN TEST PERFORMANCE (DUAL-ZONE)
For a complete wiring diagramRefer to Section 8W.
Theory of Operation
The Cooldown Test checks A/C system performance based on Evaporator Temperature Sensor input. The main cri-
teria is to lower evaporator temperature 11.11°C (20°F) within one minute. Before starting the test, the evaporator
temperature must be above 13°C (55°F) and the front blower speed must be setto high speed. When the test is
running, A/C Select and A/C Request will be on and the A/C status indicator will flash. When the test is complete,
the scan tool will display one or more test status messages to indicate the outcome of the Cooldown Test. A Suc-
cessful Cooldown – Test Passed status message indicates that the main testcriteria was met. A DTC Set During
Routine – Test Not Passed status message indicates that the A/C system is unable to lower the evaporator tem-
perature 11.11°C (20°F) within one minute. A Conditions Too Cold – Test NotRun status message indicates that the
evaporator temperature was below 13°C (55°F) when starting the Cooldown Test. A Blowers Not On High – Test Not
Run status message indicates that either the front blower speed was not setto high speed prior to starting the
Cooldown Test or the front blower speed was changed from high speed to another setting after starting the
Cooldown test. A Refrigerant Temperature Sensor Error status message indicates that a fault occurred with the
Evaporator Temperature Sensor/sensor circuits. A No Results Stored/Test Not Complete status message indicates
that the power was cycled while the test was running.
When Monitored:
When the Cooldown Test is executed.
Set Condition:
If the A/C system is unable to lower the evaporator temperature 11.11°C (20°F) within one minute.
Possible Causes
OTHER HVAC SYSTEM FAULTS PRESENT
