BYD Seal 5 airbag control unit repair(1)
1 product
What should I pay attention to with BYD Seal 5 airbag control units?
The airbag control unit in the BYD Seal 5 evaluates the crash sensors, triggers the airbags and belt tensioners, and monitors the entire airbag system. If it detects a fault, it reports it via the airbag warning light.
The control unit is a central component of occupant protection. In a collision, it decides within milliseconds whether and which airbags are triggered. To do this, it continuously checks its sensors, the supply voltage and communication within the vehicle.
After an accident, the control unit stores crash data and locks itself. Airbag24 repairs the control unit of your own vehicle that you send in. Whether every unit can be repaired is only shown by the examination in our workshop.
Which BYD Seal 5 generations are there?
We currently list one generation for the BYD Seal 5. It has been built since 2025 and is still in production.
The model series at a glance:
- 1. Generation (since 2025) – the model series, still in production.
Changes during a production period can affect software and hardware versions. For repairs, the part number on the unit therefore matters more than the generation alone.
How do I identify my BYD Seal 5 airbag control unit?
The part number on the label of the control unit determines the exact version. Together with the model year and equipment of your BYD Seal 5, it allows the unit to be assigned clearly.
Before sending in the unit, note the part number and the vehicle identification number (VIN) of your BYD Seal 5.
Fault codes provide a first clue. Examples are B1600 (driver front airbag not connected), B17A000 (internal control unit fault) and B1694 (supply voltage too low). However, a single fault code does not prove a defect in the control unit. Only the examination reveals the cause.
Which airbag equipment does the BYD Seal 5 have?
The airbag equipment of the BYD Seal 5 depends on the trim level and market. Usually, front, side and head airbags are fitted; the exact number is listed in the vehicle documentation.
The airbag control unit coordinates the deployment of these airbags. If the unit is defective or has locked after an accident, the airbag warning light may illuminate.
The repair process works as follows. Have the fault memory read out at a specialist workshop; there, the battery is disconnected and the control unit removed. Then create a repair order online and send in the unit. Work on the airbag system is safety-relevant and should be left to a specialist workshop.
Processing usually takes 3–4 working days and includes checking, repairing and testing. The repaired control unit comes back with all vehicle data and is ready for use immediately after reinstallation — coding or programming is not necessary.
