  2. Disconnect the intake actuator connector.

  3. Check that the actuator moves to the recirculation position when 12 V is applied to terminal 3 and ground to terminal 7.

    Check that the intake actuator operates to the fresh air position when the connections are reversed.

    Fresh Air 0,3 ± 0,15 Low voltage: 0.1 V or less
    High voltage: 4.9 V or more
    Recirculation 4,7 ± 0,15

    The current actuator position will be sent to the control unit.

  7. If the intake actuator does not operate properly, replace it with a known good intake actuator and check operation.

  8. Replace the intake actuator if it is determined that there is a problem with it.
