Reasons for the failure of headlight height adjustment: False alarm: If the problem "headlight height adjustment failure" appears, you can let the car stand for more than half an hour and then start it again to see if it has resolved. Headlight control program issue: It is possible that the headlights were not turned off after the car was shut down, which was recorded by the onboard computer or due to other unpredictable issues, causing the headlights to initialize. In this case, you can try reprogramming the headlight module. Whether the headlight control chip is damaged, usually the problem occurs only on one side of the headlight. In this case, you can swap the control chips on the left and right sides for inspection.
