What do you think of the car track? Do you have any skills?

It is skillful to understand the circuit diagram of a car, but there is a premise: you can understand the symbols and footprints of various components.

No matter how complex the automobile circuit is, it is also composed of multiple single circuits connected in parallel. It is very important and easy to remember to learn to look at a single power supply circuit.

When looking at the circuit diagram, first find the main electrical components of a single circuit, then analyze the power circuit and grounding circuit, and then find other related parts.

Another method is to copy a single cycle and analyze it to avoid the line-of-sight interference of other parts. There are not many things anyway.
