Description and Operation

Description

The intake actuator is located on the blower unit. It controls the intake door based on the signal from the control unit. Pressing the intake selection switch switches between recirculation and fresh air modes.

Repair Procedures

Inspection

  1. Turn the ignition off.

  2. Disconnect the intake actuator connector.

  3. Make sure the intake actuator operates in the fresh air (LHD) or recirculation (RHD) position when 12 V is connected to terminal 4 and ground to terminal 3.

    Make sure the intake actuator operates in the recirculation (LHD) or fresh (RHD) position when connected in reverse.

    Door Position Voltage (V) Fault Detection
    Fresh 0,5 Low voltage: 0.1 V or less
    Recirculation 4,5 High voltage: 4.9 V or more

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

  8. If the problem is resolved, replace the intake actuator.

Replacement

  1. Disconnect the negative (-) battery terminal.

  2. Remove the airbag.
