What are the symptoms of a faulty car computer board?

[DelChase]

Faults in a car's computer can manifest as the engine warning light staying on and internal program chaos. Below are relevant details: Introduction to car computers: The computer in a car, also known as the Engine Control Unit (ECU) or Electronic Control Module, processes simple electronic signals and computations using basic logic gates and integrated circuit principles. It receives data from various sensors throughout the vehicle, processes this information, and then sends signals to control engine operations (such as the fuel injection system and ignition timing). Typically, the ECU is located under the dashboard on the driver's side or near the windshield wiper linkage. The development of automotive computing platforms, represented by intelligent vehicle information systems (central computing systems), involves technologies such as computing, automotive electronics, communication protocols, wireless transmission, and GIS/GPS, making product development highly challenging. Precautions for diagnosing faults: When troubleshooting a car computer board fault, always start by reading the fault codes. Avoid using silicone-based sealants as they can poison the oxygen sensor due to excessive silicone content.
