Air Flow Control Actuator Inspection
- Remove air flow control actuator (1) referring to AIR FLOW CONTROL ACTUATOR REMOVAL AND INSTALLATION .
- 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
- Connect battery positive (+) terminal to terminal "a" and battery negative (-) terminal to terminal "b". Check if position of air flow control actuator changes VENT position to DEF position.
- Connect battery positive (+) terminal to terminal "b" and battery positive (-) terminal to terminal "a". Check if position of air flow control actuator changes DEF position to VENT position.
If malfunction is found, replace air flow control actuator with new one.
