What is an ECU in a car?
1 Answers
ECU is the control system of a car's engine. Below is relevant information about the car ECU: 1. Composition: It consists of a microcontroller (MCU), memory (ROM, RAM), input/output interfaces (I/O), analog-to-digital converters (A/D), as well as shaping, driving, and other large-scale integrated circuits. 2. Automatic diagnostic function: ECUs generally have self-diagnosis and protection functions. When a system failure occurs, it can automatically record the fault code in RAM and take protective measures to read substitute programs from the aforementioned inherent programs to maintain engine operation. At the same time, these fault messages will be displayed on the dashboard and remain illuminated, allowing the car owner to promptly identify the issue and drive the car to a repair shop.
