The functions of the self-diagnosis system are: 1. Automatically inspect and monitor the transmission system, control system, and various working conditions within the vehicle; 2. When a fault occurs in the vehicle, the malfunction indicator light installed on the dashboard will flash to warn the owner of the problem; 3. By pressing a button, the fault code will be displayed on the dashboard. The reasons why the self-diagnosis system cannot retrieve fault codes are: 1. Open or short circuits in the wiring connecting the ignition switch, ECU, malfunction warning light, and communication interface; 2. ECU malfunction leading to abnormal output signals from the self-diagnosis system; 3. Damage to the malfunction warning light or communication interface.

During traffic jams, all vehicles are stationary, and car exhaust will inevitably disperse in the air. Open the sunroof after exposure to sunlight to balance the interior temperature. In hot summers, after the car has been exposed to the sun, the interior temperature becomes very high. At this time, the owner should promptly open the car's sunroof.
