Set Condition

The A/C Heater Control uses a pulse feedback to the controller to detect the total door movement range. If the amount of pulses required to move the door completely in both directions is greater than what the controller has stored in its memory, this DTC will set. If an Actuator Calibration Test is performed or during normal operation and the A/C Heater Control detects a valid range of the door movement span in both directions, the DTC will change from Active to Stored and will stay in the controllers memory for 100 ignition cycles.
