DISCHARGE HEADLIGHT SERVICE WARNINGS

Discharge Headlight Service Warnings

- To prevent electrical shock when replacing the discharge headlight, dry hands thoroughly, and carry out work in an area out of rain.

- When the light switch is on, approx. 25,000 V of high voltage passes through the discharge headlight. Because of the danger of electrical shock, do not insert fingers or a tester.






- When the headlights are on, high voltage flows around the socket and discharge headlight. When turning on the discharge headlights while working, always leave the headlights in the vehicle-installed condition to prevent electrical shock.

Discharge Headlight Control Module Service Warnings

- Because of the danger of electrical shock, when inspecting with a tester, do not inspect the discharge headlight control module as a single module or disassemble it.






Discharge Headlight Control Module Reuse

- If the discharge headlight control module is dented or damaged in any way, replace the unit with a new one to prevent electrical shock and improper operation.

- Although the unit may temporarily operate normally even though it has received an impact, it is possible that the interior may have been damaged. When reusing the module, inspect the following items regarding discharge headlight illumination to verify that there are no malfunctions.

- Verify that the discharge headlights illuminate normally by testing them several times under cold illumination (headlights off for approx. 10 min or more and then turned on) and hot illumination (headlights on for approx. 15 min or more, turned off for approx. 1 min, and then turned on again) conditions.
- Inspect the headlight illumination in the period from directly after cold illumination until they are uniformly illuminated (approx. 5 min) and verify that there is no flickering or inconsistent brightness.
- Turn on the headlights for approx. 30 min with normal condition discharge headlights and verify that there is no brightness difference between the right and left, and that illumination is consistent.
