Air Flow Control Actuator Inspection

  1. Remove air flow control actuator (1) referring to AIR FLOW CONTROL ACTUATOR REMOVAL AND INSTALLATION .
  2. Check resistance between "d" and "e" terminals.

    Air flow control actuator resistance 

    DEF position: Approx. 700 Ω 

    FOOT/BENT position: Approx. 1.7 kΩ 

    FOOT position: Approx. 2.4 kΩ 

    BI-LEVEL position: Approx. 3.9 kΩ 

    VENT position: Approx. 5.1 kΩ 

  3. Connect using service wire, battery positive (+) terminal to terminal "a" and battery negative (-) terminal to terminal "b". Check if position of air flow control actuator lever changes from VENT position to DEF position.
  4. Connect using service wire, battery positive (+) terminal to terminal "b" and battery negative (-) terminal to terminal "a". Check if position of air flow control actuator lever changes from DEF position to VENT position.

    If malfunction is found, replace air flow control actuator with new one.
