- The HVAC Module learns the normal open position voltage and the normal closed position voltage of the door during an actuator calibration test. If the learned closed position (0%) is less than 0.34 volts, or learned open position (100%) is more than 4.60 volts, this DTC will set.
NOTE:
Front Mode Door normal operating position signal voltages:
FRONT MODE DOOR - POSITION VS SIGNAL VOLTAGE
| Door Position | Minimum Position Signal Voltage | Nominal Operating Position Signal Voltage | Maximum Position Signal Voltage |
|---|---|---|---|
| Panel | 0.70v | 0.72v | 0.73v |
| Bi-Level | 1.49v | 1.52v | 1.55v |
| Purge | 2.31v | 2.36v | 2.41v |
| Floor | 2.80v | 2.86v | 2.92v |
| Mix | 3.28v | 3.34v | 3.41v |
| Defrost | 4.20v | 4.28v | 4.37v |
The door may travel outside these values (0.70v - 4.37v) during Actuator Calibration Test. The Actuator Calibration Test is triggered when a new HVAC Module is installed, a battery disconnect has occurred, or when commanded by the scan tool.
