Airbags & Safety

Airbag modules are single-use pyrotechnic safety devices that must be replaced after deployment or when past their service life — there is no repair option for a deployed airbag. BYD's airbag systems are controlled by the SRS ECU and require precise connector alignment, correct torque specifications, and module pairing during installation. This category covers driver's airbag modules, front passenger airbag modules, left and right side curtain airbag modules, SRS electronic control units, and airbag indicator covers for BYD Atto 3, Dolphin, Sealion 7, and Denza D9. Only OEM or certified aftermarket modules should be used to ensure proper deployment timing, force distribution, and occupant protection in a collision event.
