Air Flow Control Actuator Inspection
- Remove air flow control actuator referring to AIR FLOW CONTROL ACTUATOR REMOVAL AND INSTALLATION .
- Check resistance between terminals.
Air flow control actuator resistance
Terminal "d" and "e" (DEF position): Approx. 250 - 350 Ω
Terminal "c" and "d" (DEF position): Approx. 2.6 kΩ
Terminal "d" and "e" (VENT position): Approx. 2.6 kΩ
Terminal "c" and "d" (VENT position): Approx. 250 - 350 Ω
- Connect battery positive (+) terminal to terminal "b" and battery negative (-) terminal to terminal "a". Check if position of air flow control actuator changes VENT to DEF.
- Connect battery positive (+) terminal to terminal "a" and battery positive (-) terminal to terminal "b". Check if position of air flow control actuator changes DEF to VENT.
If malfunction is found, replace air flow control actuator with new one.
