Summary
SOME VEHICLES MAY EXHIBIT THE HEADLIGHTS FLICKERING WHEN THE VEHICLE IS DECELERATING (BY APPLYING THE BRAKES) WITH THE HEADLIGHTS ON. THIS CONCERN IS CAUSED BY INADEQUATE ALTERNATOR OUTPUT (CONTROLLED BY THE PCM) WHEN THE BATTERY IS UNDER A HEAVY LOAD. TO CORRECT THE PROBLEM, THE CONTROL LOGIC OF THE PCM HAS BEEN CHANGED.
