BYD Atto 3 wiring diagrams

Drawings that show how every wire, connector, fuse, relay and control module in the car is connected.

Trace a wire from one part to another
Find which fuse or relay feeds a circuit
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 Atto 3 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

Independent workshopsRepair BYD cars without waiting for dealer information.

Auto electriciansTrace circuits, fuses, connectors and pin numbers in minutes.

Fleet & taxi mechanicsKeep BYD fleets on the road with the right procedures.
