Where is the Tianzhu sunshine sensor?

The location of Scorpio's sunlight sensor: a small circular sensor in the middle of the front of the workbench, next to the windshield outlet in front of the dashboard. Principle of sunlight sensor: The sunlight sensor is used in the control system of automobile automatic air conditioner, and its function is to detect the change of sunshine by photodiode, so as to adjust the outlet temperature and air volume of air conditioner. The following are the precautions for sensor testing: 1. Unless otherwise specified in the test process, pointer multimeter should not be used to test ECU and sensor, but high impedance digital multimeter or automobile multimeter should be used to test. 2. It is forbidden to check the on-off state of the transistor circuit by striking a light. Do not use ordinary test lights to test any electrical equipment connected to the ECU to prevent the transistor from being damaged. The pulse circuit should be checked with LED lamp or oscilloscope. 3.ECU and sensor must be moisture-proof, the sealing device of microcomputer or sensor is not allowed to be damaged, and it is not allowed to be washed with water. The ECU must be protected from violent vibration.
