Inspection 1. Turn ignition switch OFF. 2. Remove the battery and battery tray. (Refer to Engine Electrical System - "Battery") 3. Disconnect the solenoid valve connector (A).
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, turn the power on GDS.
Replacement 1. Disconnect the negative (-) battery terminal. 2. Remove the heater and blower unit.(Refer to HA group – heater unit). 3.
