What does the stop light mean?

[Toni]

The stop light on the car dashboard is a mandatory parking alarm light. Here is the relevant content introduction: 1. If the stop light on the car is on, it may indicate abnormalities in the braking system, engine oil pressure, or coolant temperature. If this light comes on while the engine is running, you must immediately stop and turn off the engine. 2. Generally, cars equipped with microprocessor control units have a fault self-diagnosis system, which can be used to automatically check and monitor the working status of various parts of the car's transmission system and control system. When a fault occurs in the car, the fault indicator light on the dashboard will flash to warn the owner that there may be a problem with the car. By pressing a button, the fault code will be displayed on the dashboard. At the same time, this fault signal will be stored in the memory. Even if the ignition switch is turned off, the fault is resolved, and the fault indicator light goes out, the fault signal will still remain in the memory for maintenance personnel to determine the fault location of the car. After the fault is resolved, disconnecting the ECU power for 30 seconds will clear the fault code.
