What does car code mean in Chinese?

[SadieMarie]

Car code represents the meaning of indicating the need for indicator light (fault light) self-check. Here is some introduction about car code: 1. Car code is the system of the car detection chip. If the chip cannot be detected, the dashboard will light up. When this sign lights up, the driver cannot start the car. Attempting to ignite multiple times will lock the engine, commonly known as engine anti-theft. 2. Working principle: The car ignition key contains an electronic chip, and each chip has a fixed ID (equivalent to an identification number). Only when the ID of the key chip matches the ID on the engine side can the car be started.
