Removal 1. Disconnect the negative (-) battery terminal. 2. Remove the glove box housing (A). (Refer to Body - "Glove Box") 3. Remove the PGS unit (A) after loosening the nuts.
Diagnosis With GDS 1. BSD system defects can be quickly diagnosed with the GDS. GDS operates actuator quickly to monitor, input/output value and self diagnosis. 2. Connect the cable of GDS to the data link connector in driver side crash pad lower panel, and turn on the GDS.
Inspection 1. Turn the ignition switch OFF. 2. Disconnect the intake actuator connector. 3. Verify that the intake actuator operates to the fresh position when connecting 12V to terminal 3 and grounding terminal 4. Verify that the intake actuator operates to the recirculation position when connected in reverse.
