What is the code for the HVAC actuator?
• B0414 is for the left air temperature actuator. • B0424 is for the right air temperature actuator. • B3770 is for the mode actuator. The HVAC control module controls the HVAC door actuators to regulate the airflow through the HVAC system. Each actuator consists of a stepper motor, a logic circuit, and a potentiometer.
What happens when the HVAC actuator fails to calibrate?
• If the DTC sets because the actuator failed a calibration, the HVAC control module will attempt to calibrate the motor in the next transition from OFF to RUN mode. • The DTC will become history if the HVAC control module no longer detects the condition that set the DTC.
What are the DTCs for HVAC door actuators?
The following DTCs are for the HVAC door actuators: • B0229 is for the recirculation actuator. • B0414 is for the left air temperature actuator. • B0424 is for the right air temperature actuator. • B3770 is for the mode actuator. The HVAC control module controls the HVAC door actuators to regulate the airflow through the HVAC system.
How is the HVAC control module calibrated?
The HVAC control module calibrates the travel range of the HVAC door actuators when it is initially powered by the battery positive voltage circuit. During calibration, the module commands the actuators in each direction until door travel is stopped.
