What is the reason why the Peugeot's stop light returns to normal after restarting?

STOP light may illuminate due to abnormalities in the braking system, engine oil pressure, or coolant temperature. The solutions for the STOP light being on and an introduction to the STOP light are as follows: Solutions for the STOP light being on: If the light comes on while the engine is running, you must stop immediately and turn off the engine. Introduction to the STOP light: This light is connected to warning lights for oil pressure, brake fluid level, and the coolant temperature gauge. If the light flashes while the engine is running, you must stop immediately and turn off the engine. Oil pressure warning light: This light is connected to the central STOP warning light. If this light comes on while the engine is running, accompanied by a buzzer sound, and the multifunction display shows that the engine oil pressure is too low, stop immediately. If the lubrication system is low on oil, add oil to the proper level. Parking brake and low brake fluid level warning light: This light is connected to the central STOP warning light. It comes on every time the ignition switch is turned on.
Sometimes when I drive my Peugeot, the STOP light suddenly comes on, but after restarting the vehicle, it returns to normal, which I find quite puzzling. From my years of driving experience, the most common cause is false sensor readings—for instance, the oil pressure sensor or brake fluid level sensor momentarily failing to detect data, triggering the warning light. Additionally, electrical system issues are also common, such as poor wiring connections or voltage instability causing the computer to misinterpret signals. Restarting the car essentially 'resets' the system, and once the error disappears, everything returns to normal. However, it's important to note that this could be a precursor to more serious problems, like aging circuits or ECU software bugs. If left unchecked, these issues may recur later. My advice is to first perform simple checks on fuses and fluid levels when this happens. If it occurs frequently, it’s best to visit a 4S dealership to read the fault codes with a diagnostic tool and thoroughly eliminate potential risks. After all, the STOP light is related to safety—don’t take it lightly.
