4.8What is a BYD Seal U 1st generation airbag control unit?
In the BYD Seal U 1st generation, the airbag control unit works as the central control unit of the restraint system (SRS). It reads out the crash sensors and, in an accident, decides within milliseconds which airbags and seatbelt pretensioners deploy.
This control unit is fitted in the since 2024 model series. It is the link between the sensors and the restraint devices: only its evaluation of the signals decides what happens in an emergency.
It also stays active during normal driving, continuously monitors the whole system and indicates faults via the airbag warning light. If an accident occurs, the unit stores crash data and locks itself.
Why is the BYD Seal U 1st generation airbag control unit defective?
Most often the cause is crash data stored in the unit after an accident, even if no airbag deployed. Other reasons for a defective BYD Seal U 1st generation airbag control unit are aged components, cold solder joints, corrosion and moisture at the connectors, and voltage spikes.
An ordinary diagnostic tool cannot remove such crash data. The airbag warning light stays on, even if the bodywork has long been repaired.
Voltage spikes can be caused, for example, by a weak battery or by jump-starting. Electronic components on the circuit board age over the years, solder joints lose their strength, and moisture attacks contacts.
How you can tell: the airbag warning light stays on continuously, the fault memory cannot be reset, or the diagnostic tool cannot get access to the control unit.
Common error codes for BYD Seal U 1st generation airbag control unit repair
Depending on the code, the error codes of the BYD Seal U 1st generation airbag control unit relate to the data connection to other control units, the internal electronics, the power supply, the firing circuits of the airbags or stored crash data.
A code therefore first points to one part of the system: the control unit itself, the wiring and connectors, a connected airbag module or the on-board voltage. Among others, these codes and their meanings are known for this vehicle:
- B16AE00 → Fault in the SRS control unit
- B17A000 → Internal control unit fault
- B17A200 → Crash recording is locked
- B17A600 → Frontal impact detected and stored
- B17A800 → CAN bus communication interrupted
- B1694 → Supply voltage too low
- B1695 → Supply voltage too high
- B1600 → Driver front airbag not connected
Read out the codes with a diagnostic tool. A single code does not reliably show which part has actually failed, because connectors, wiring or an airbag module are just as likely a cause as the control unit. Only an inspection narrows down the cause.
What part numbers are available for the BYD Seal U 1st generation airbag control unit repair?
You will find the part number on the label of your BYD Seal U 1st generation airbag control unit. It determines the exact version, because within a model series there are different numbers depending on equipment and year of manufacture.
Remove the unit from the vehicle, read the number from the label and enter it in the repair order. This establishes which version is concerned.
However, the number does not tell you whether the unit is defective. That only becomes clear from the fault memory that has been read out and from the inspection at Airbag24.
How to proceed: have the fault memory read out, then disconnect the battery and remove the control unit. Create a repair order online and send in the unit. Testing, repairing and checking usually take 3–4 working days at Airbag24.
The repaired control unit comes back with all vehicle data and is ready for use as soon as it is refitted — no coding or programming is required.
