What should I know about BYD Atto 2 airbag control units?
The airbag control unit in the BYD Atto 2 evaluates the crash sensors, triggers the airbags and belt tensioners, and monitors the entire airbag system. If it detects a fault, the airbag warning light on the dashboard comes on.
After an accident, the control unit stores crash data and locks itself. Airbag24 repairs the control unit you send in, at our workshop in Berlin. This includes erasing the crash data after an accident and checking for faults.
Which BYD Atto 2 generations are there?
The BYD Atto 2 has been built since 2025 in its first generation. It is available as a battery-electric variant and as a plug-in hybrid with DM-i drive.
The BYD Atto 2 is a compact SUV from BYD. The list below shows both variants separately, because the drive system differs.
- 1. Generation (since 2025) – battery-electric variant
- 1. Generation DM-i (since 2025) – plug-in hybrid with DM-i drive
Which variant is fitted in your vehicle depends on the drive type, the year of manufacture and the vehicle identification number (VIN).
How do I identify my BYD Atto 2 airbag control unit?
The part number on the label of the control unit determines the exact version. The year of manufacture, drive type and equipment of your BYD Atto 2 show which version to expect.
Read the part number off the housing before you send the unit in. The vehicle identification number (VIN) also helps to assign the unit clearly to your vehicle.
The fault memory may show codes such as B1600 (driver front airbag not connected), B1694 (supply voltage too low) or B17A200 (crash recording locked). However, a single fault code does not prove that the control unit is faulty; a specialist workshop determines the cause.
Which airbag equipment does the BYD Atto 2 have?
According to test reports on the models sold in Australia, the BYD Atto 2 has front, side and curtain airbags, six in total. The number and position of the airbags can differ by market and trim level.
Which airbags are fitted in your vehicle depends on the market and trim level. If in doubt, the vehicle identification number (VIN) helps to clarify the exact configuration.
This is how the repair works: have the fault memory read out, disconnect the battery and remove the control unit. Then create a repair order online and send the unit in by parcel. Processing usually takes 3–4 working days: checking, repairing and testing.
The airbag system is safety-critical. If you are unsure about removing the unit, have a specialist workshop carry it out.
The repaired control unit returns with all vehicle data and is ready for use immediately after reinstallation — coding or programming is not required.
