What should be considered with BYD Seal 6 airbag control units?
If the airbag control unit of the BYD Seal 6 is defective or shows irregularities after an accident, diagnosis should be carried out by a specialist workshop. The control unit evaluates the crash sensors and triggers the airbags and belt tensioners.
The control unit monitors the entire airbag system. If it detects a fault, it reports this via the airbag warning light. As the airbag system is safety-relevant, only specialist businesses should carry out work on it.
After an accident, the control unit stores crash data and locks itself. Airbag24 repairs the customer's own control unit and erases the crash data in the process. Whether a specific fault can be repaired can only be determined by testing.
Which BYD Seal 6 generations are there?
The BYD Seal 6 has been built since 2025 in its first generation, as a saloon and as a Touring. Both versions belong to the same generation and differ in body style.
Whether a vehicle is a saloon or a Touring can be seen from its body style. This classification helps to find the correct control unit, as airbag control units can be designed differently depending on the variant.
- 1. Generation (since 2025) – saloon
- 1. Generation Touring (since 2025) – Touring estate
How do I identify my BYD Seal 6 airbag control unit?
You can identify the airbag control unit of the BYD Seal 6 by the part number on its label, the year of manufacture and the vehicle identification number (VIN). The part number determines the exact design of the unit.
The part number on the control unit's label is the most important reference point. Note it down together with the year of manufacture and the equipment of your vehicle before you create a repair order.
A fault code alone does not prove a defect. As examples from our fault data for this model, we list:
- B1600 – driver front airbag not connected
- B17A200 – crash recording locked
- B1694 – supply voltage too low
What airbag equipment does the BYD Seal 6 have?
The airbag equipment of the BYD Seal 6 depends on the trim level. According to published equipment lists, the driver and front passenger airbags, front side airbags and side curtain airbags belong to the Comfort trim.
The Boost trim additionally lists a front centre airbag. We do not state a total number of airbags, as the available information differs. Which airbags are actually fitted in your vehicle follows from its equipment and the VIN.
The airbag system is safety-relevant, so the fault memory should first be read out in a specialist workshop. The route to repair then looks like this:
- Have the fault memory read out in a specialist workshop.
- The specialist workshop disconnects the battery and removes the control unit.
- Create a repair order online with Airbag24.
- Send the control unit to Airbag24 by parcel.
