[VanSebastian]

The method to reset the BMW onboard computer is to disconnect the positive and negative terminals of the battery, reconnect the battery, turn the key to the ON position and then to the OFF position, turn the key to the ON position again, and then start the engine. Introduction to the onboard computer: The car onboard computer is generally used in fuel injection vehicles. It is mainly used to control fuel injection quantity, air-fuel mixture ratio, etc. It consists of a microcomputer and peripheral circuits. The microcomputer integrates a microprocessor (CPU), memory, and input/output interfaces on a single chip. Components of the onboard computer: The main part is the microcomputer, with the CPU being the core component. The ECU converts input signals into digital form, processes them by comparing with stored reference data, calculates output values, and then amplifies the output signals to control several servo components. The onboard computer can display real-time fuel consumption, average fuel consumption, remaining fuel, driving range, engine speed, intake pressure, acceleration performance, coolant temperature, and other basic data. Most importantly, it can display vehicle fault information.
