Abstract: According to the failure or intermittent failure of the FC-3AB ambient light sensor that feedback from the production site of Geely Automobile, the vehicles in this condition were tested and it is found that after the key hits the ignition lock ON file and switch the AUTO file, ark light environment (palm cover sun sensor) lights automatically open function is failure. When the car headlight is turned on manually, the headlight can be turned on, indicating that there is no problem with the car headlight. In this paper, the factors that cause the failure are collated and analyzed, and the fish bone map is drawn. Through the analysis of the quality of the ambient light sensor and the analysis of the process steps, it is determined that the solution is to seal the sensor assembly to ensure that the internal circuit of the shell does not fail due to moisture, the headlights of the car can be turned on normally, and the light in the car can be automatically adjusted. Eventually, the corre ctness of the solution is verified through experiments, and the failure rate of the automotive ambient light sensor is minimized, effectively improving the reliability of the ambient light sensor and the safety of driving.
