Inspection

  1. Turn the ignition off.
  2. Disconnect the intake actuator connector.
  3. Check that the intake actuator moves to the fresh air position when 12 V is applied to terminal 3 and ground is applied to terminal 4. Check that the intake actuator moves to the recirculation position when the connections are reversed.

    Door Position Voltage (V) Fault Detection
    Fresh Air 0,5 ± 0,15 Low voltage: 0.1 V or less
    Recirculation 4,5 ± 0,15 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. Replace the intake actuator if it is confirmed to be faulty.

Diagnosis Using GDS

  1. The heating, ventilation, and air conditioning system faults can be quickly diagnosed using the Global Diagnostic System (GDS). ※ The GDS provides the following information: (1) Self-diagnosis: Check and display of diagnostic trouble codes (DTC). (2) Current data: Check the input/output status of system data. (3) Active test: Check the operating status of the system. (4) Additional functions: Other controls such as system option and zero point adjustment.
  2. Select "Vehicle Model" and the system to be checked to inspect the vehicle with the tester.
  3. Select the "Current Data" menu to check the current input/output data status. The input/output data for the sensors related to the intake actuator can be checked.
  4. To perform a forced operation on the intake actuator input factors, select "ACTUATOR CHECK".

Replacement

  1. Disconnect the negative (-) battery terminal.
  2. Remove the driver airbag module assembly. (Refer to Body - "Driver Airbag Module Assembly")
  3. Disconnect the connector, then remove the intake actuator (A) after loosening the mounting screws.
  4. To install, reverse the removal procedure.
