What should I pay attention to with BYD Seal airbag control units?
The BYD Seal airbag control unit evaluates the crash sensors, triggers airbags and belt tensioners, and reports faults via the airbag warning light. After an accident, it stores crash data and locks itself. Airbag24 repairs your own control unit when you send it in.
The control unit monitors the entire airbag system. If it detects a fault, the airbag warning light in the vehicle comes on. A defective control unit can impair the function of the system, so the cause should be clarified promptly.
The airbag system is safety-relevant. Work on the airbag system belongs in the hands of a specialist workshop. Independent interventions are not advisable, because the system must work reliably in an emergency.
Which BYD Seal generations are there?
The BYD Seal is listed as 1. Generation. This generation has been built since 2023 and is still in production. Build year and equipment determine the correct assignment.
- 1. Generation (since 2023) – current series, still in production.
The series designation is the first point of reference. Which version is fitted in your vehicle is shown mainly by the part number on the control unit and by the vehicle data.
How do I identify my BYD Seal airbag control unit?
The part number on the label of the control unit determines the exact version. The build year and equipment of your BYD Seal also count.
The part number is the most important point of reference, because it shows the version of the control unit. The build year and the vehicle identification number (VIN) are listed in the vehicle documents and help to classify the vehicle correctly.
Fault codes from the memory give clues, for example B1600 (driver front airbag not connected), B1694 (supply voltage too low) or B17A200 (crash recording locked). However, a code alone does not prove a defect; only testing the control unit shows what is actually present.
What airbag equipment does the BYD Seal have?
The BYD Seal comes with front, side and head airbags as standard. According to manufacturer information, a front centre airbag is also fitted. The exact number depends on the equipment and should be checked against the manufacturer's equipment list.
The equipment includes airbags for driver and front passenger, side airbags for chest and pelvis, and side head airbags. The side and head airbags are provided for the driver, front passenger and rear seat positions. Whether a knee airbag is also fitted should likewise be checked in the equipment list.
The repair of the BYD Seal airbag control unit works as follows: first, have the fault memory read out. A specialist workshop then disconnects the battery and removes the control unit. Next, a repair order is created online and the unit is sent to Airbag24. Processing usually takes 3–4 working days (checking, repairing, testing).
The repaired control unit returns with all vehicle data and is ready for use as soon as it is refitted; no coding or programming is required.
