Component Location1. Auto light sensor2. Head lamps3. Lighting switch (Auto)4. Rear combination lamp5. BCM (Body Control Module)
DescriptionIt's a system that uses illumination sensor to automatically turn ON the tail lamp and head lamp based on the change in surrounding environment's illumination condition.
Diagnosis With GDS1.The heating, ventilation and air conditioning can be quickly diagnosed failed parts with vehicle diagnostic system (GDS).※ The diagnostic system (GDS) provides the following information.(1) Self diagnosis : Checking the failure code (DTC) and display.
Inspection1.Check the resistance of the ambient temperature sensor between terminals 1 and 2 whether it changes by changing the ambient temperature.1. Ambient Sensor (+)2. Sensor groundSpecification Ambient temperature [°C (°F)] Resistance between terminal 1 and 2 (
