Mazda 323 Airbag Control Module Replacement Parts

Yes, the Mazda 323 was fitted with an airbag control module (also called an SRS control unit) on variants equipped with airbags, which became standard across most trim levels from the mid-1990s onwards. Earlier 323 models from the late 1980s and very early 1990s did not have airbags at all, so if your car is from that era it will not have this unit. If you are unsure whether your specific car has an airbag system, check for an SRS warning light on the dashboard or confirm with the breaker against your registration.

The 323 ran across several distinct generations — the BF (roughly 1985–1989), BG (1989–1994), BA (1994–1998), and BJ (1998–2004) — and the airbag control module is generation-specific, so a unit from a different generation is very unlikely to be compatible. Even within a generation there can be differences depending on trim level and the exact SRS system fitted, so you should always confirm compatibility with the breaker against your registration before buying. Never assume a unit will plug straight in without that check, as airbag systems are safety-critical.

No — the BJ and BA are different generations with different body structures, wiring architectures, and SRS systems, so their airbag control modules are not interchangeable. This is one of the most common cross-generation mix-ups, so always quote your registration to the breaker and ask them to confirm the part matches your specific generation and SRS configuration. Fitting an incompatible module could mean airbags fail to deploy correctly, which is a serious safety risk.

Trim level can matter for the 323 because higher-spec trims sometimes had additional airbags (for example, side airbags), and the control module must match the number and type of airbags in your car's SRS system. If your car and the donor car have the same airbag count and configuration, the trim name itself is less important than the actual SRS setup, but you should confirm the pretensioner variant and module compatibility with the breaker against your registration rather than assuming trims are identical. This is a safety-critical part, so professional fitting is strongly recommended.

For the airbag control module itself, door count is generally not a primary factor in the same way it is for, say, a body panel, but the overall SRS configuration in your car (including any side or curtain airbags) can vary between body styles. It is worth telling the breaker both your door count and your full SRS setup so they can match the donor car as closely as possible. As always, confirm compatibility against your registration before purchasing, and have the unit fitted by a qualified technician.

Airbag systems are safety-critical, and fitting or disturbing them incorrectly can cause accidental deployment or, equally dangerously, prevent deployment in a real accident — so professional fitting by a qualified technician is strongly recommended. A used module should also be checked to ensure it has not been previously triggered, as airbag control modules can store fault codes or be locked after a deployment event, meaning the unit may need resetting or coding after installation. Always ask the breaker for the service history of the part where possible, and have the system tested with a diagnostic tool after fitting.
