  5. LIGHT CONTROL ECU OPERATION CHECK


    1. Perform the following illumination diagnosis when both of the following conditions are met: 1) the light control ECU is not visibly damaged, and 2) the light control ECU has been struck but is operating normally. If all of the following diagnosis results are normal, the light control ECU can be reused.


      1. Perform low beam headlight illumination cold starts (10 minutes or more off, then turned on) and hot starts (15 minutes or more on, 1 minute off, then turned on again) several times. Check that the low beam headlights illuminate normally.

      2. For 5 minutes immediately after a light illumination cold start (before the lights stabilize), visually check the illumination condition and check that the lights do not flicker or show signs of instability.

      3. Install bulbs that have approximately the same usage time, and illuminate the low beam headlights for approximately 30 seconds. Check that the brightness of the left and right bulbs is approximately the same, and that the illumination is stable.

        Tech Tips

        Judging whether the discharge headlight bulb is poor by examining it externally is difficult. Therefore, quality is judged changing the discharge headlight bulb with a known good one and turning the light switch on.
