How to Check Discharge Headlight Components

HOW TO CHECK DISCHARGE HEADLIGHT COMPONENTS.




VISUAL CHECK OF THE CONTROLLER (CASE)
If any of the defects below are found, replace the controller.

CHECK THE WIRING HARNESS BETWEEN THE CONTROLLER AND THE BULB.
If any of the defects below are found, replace the wiring harness between the controller and the bulb.






CAUTION: If the wiring harness between the controller and the bulb is defective, always replace it. Attempting to repair the wiring harness may cause a melted harness wire.

CHECKING WHILE THE HEADLIGHTS ARE ON
If any of the defects below are found, replace the controller.

WARNING: While the headlights are on, do not touch the headlight bulbs. There is a high risk of scalding, as the headlight bulb will become extremely hot.






NOTE: Ensure that the headlight control system and its circuit (power supply control at engine start and during steady illumination, high-voltage generating circuit, etc.) are working normally. Then check whether internal breakage has occurred in the controller. However, some internal breakage may not be able to be found.
