  • Check connector pin numbers and wire colours

In the diagram viewer every clickable component code is marked in blue: click it to see every linked diagram and where the part sits in the car. How to read BYD wiring diagrams.

BYD M6 diagnostic manual (fault codes)

Guides for finding faults: what each fault code (DTC) means and the tests that find the cause.

  • Look up a fault code (DTC) and its causes
  • Follow step-by-step tests with expected values
  • Diagnose a symptom when there is no code

Guide to BYD fault codes (DTC).

Right-hand drive or left-hand drive?

The electronics and mechanics are the same. What changes is where parts are, because the driver sits on the other side.

Who uses it
