DISCHARGE HEADLIGHT CONTROL MODULE REUSE
If the discharge headlight control module is dented or damaged in any way, replace the module
with a new one to prevent electrical shock and improper operation.
Although the control module may temporarily operate normally even though it has received an
impact, it is possible that the interior may have been damaged. When reusing the control 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 bulbs and verify that there
is no brightness difference between the right and left, and that illumination is consistent.
