Action Taken When the DTC Sets

WARNING: This page does not describe the selected car, but rather 8 other vehicles, including the 2003 GMC Yukon XL, 2003 GMC Yukon, 2003 Chevrolet Tahoe, 2003 Chevrolet Suburban, and 2003 Chevrolet Avalanche. However, it is still accessible from the selected car via links, so may be relevant.

If the DTC sets because the actual door position value is out of range, the auxiliary HVAC control module will command the actuator to a default position.
If the DTC sets because the actuator failed a calibration, the auxiliary HVAC control module will attempt to calibrate the motor in the next transition from OFF to RUN mode.
