BYD Han airbag control unit repair(1)
1 product
What should I pay attention to with BYD Han airbag control units?
The airbag control unit in the BYD Han evaluates the crash sensors, triggers the airbags and monitors the entire airbag system. If it detects a fault, it shows this via the airbag warning light. Airbag24 repairs the control unit you send in for your own vehicle.
The control unit triggers airbags and belt tensioners in a collision. After an accident, it also stores crash data and locks itself. A defective or locked control unit can impair the function of the entire airbag system, so a warning light that stays on should be checked promptly.
Airbag systems are safety-relevant. Diagnosis, removal and testing should therefore be carried out by a specialist workshop; nobody should work on the airbag system themselves. Airbag24 repairs the removed control unit at its own workshop in Berlin and returns it afterwards.
Which BYD Han generations are there?
The BYD Han is listed here as the 1st generation, with a production period from 2023 to 2025. The production year of your vehicle is decisive for the classification.
The BYD Han is a saloon from the Chinese manufacturer BYD. It was launched in Europe in 2023, including in Italy.
Within the production period, software and equipment can differ by market and trim level. Have the production year and equipment of your vehicle ready before you create a repair order.
- 1st generation (2023–2025) – the generation of the BYD Han listed in the shop.
How do I identify my BYD Han airbag control unit?
The part number on the control unit determines the exact version. Together with the production year and equipment of your BYD Han, it allows the matching unit to be identified clearly.
The part number is attached to the control unit itself. Note it down before the unit is removed and keep it ready together with the production year.
Fault codes from the fault memory give a first indication, for example B1600 (driver front airbag not connected), B1694 (supply voltage too low) or B17A200 (crash recording locked). A single code does not, however, prove a defect in the control unit. A specialist workshop clarifies the cause with a complete diagnosis.
What airbag equipment does the BYD Han have?
According to the manufacturer's information, the BYD Han has front, side and curtain airbags. How many modules are fitted depends on the market and trim level, so we do not state a fixed total.
The manufacturer's information lists airbags for driver and front passenger, side airbags at the front and rear, and curtain airbags for both rows of seats. Further modules can be added depending on the equipment. This is why the equipment of your vehicle is part of identifying the control unit.
To get the unit repaired, have the fault memory read by a specialist workshop. The workshop disconnects the battery and removes the control unit. Then create a repair order online and send the unit to Airbag24.
Processing usually takes 3–4 working days: we check the unit, repair it and test it afterwards. The repaired control unit comes back with all vehicle data and is ready for use immediately after reinstallation — no coding or programming is required.
