Airbag control module

The airbag control module, also called the SRS module or airbag ECU, is the small computer that reads the crash sensors, fires the airbags and seatbelt pretensioners at the right moment, and logs the event in a collision. It usually sits under the centre console or a front seat, and after a crash it stores fault codes that must be reset, or the module replaced, before the airbag warning light will clear.The clearest sign of a failing module is an airbag warning light that will not clear, often with stored fault codes. Some faults reset, but water, corrosion, or burned circuits mean replacement, not repair. Signs to watch for:

• A dashboard airbag light that stays lit.
• Stored crash data that locks the system after a deployment.
• Airbags or pretensioners failing to fire in an impact.
• Communication faults with the car's network.
• Water or corrosion from a wet footwell.

You can drive with the module dead or removed, but the airbags will not fire, the light stays on, and it can fail an MOT. A dead airbag control module looks normal but gives no airbag protection in a crash, so never leave the warning light unfixed. A used airbag module is the cheap route, scattered across breaker sites.Parthunt24 sets out used airbag control module listings from marketplaces like eBay, Ovoko, ProxyParts and TotalParts, lining 2963 offers up so price, fitment, and condition are easy to compare before you commit to a seller.

An airbag control module is matched to your car's exact SRS, and most will not work until they are coded to it, so the part number matters more than the look.Match the make, model, year, body style, and OEM part number first, then the SRS generation, the ECU hardware and software, the airbag count, and the connector. Coding or a crash-data reset is usually needed, and it must be virgin or properly reset. A module that is not coded or reset to your car can leave the airbag system dead, so this step is not optional.Add your car to the filters on the Parthunt24 results, and only modules built for it show.

• Vehicle compatibility: Match make, model, year, body style, and OEM part number exactly.
• OEM part number: The most critical identifier for the correct replacement.
• SRS system version: Must match the vehicle’s airbag system generation.
• ECU hardware number: The revision must be compatible or an approved one.
• Software coding: The module may need VIN coding or parameterisation.
• Crash data status: Must be virgin or properly reset after a deployment.
• Airbag system configuration: Front, side, and curtain count must match.
• Connector type: Plugs must match exactly, with no adaptation.
• CAN bus compatibility: Must communicate correctly with the vehicle network.
• Steering wheel position: Left-hand-drive and right-hand-drive variants may differ.
• Transmission/body variant: Saloon, SUV, and van setups can differ.
• Condition: Check for water damage, corrosion, burned circuits, or crash history.

On the seller's listing, the part numbers and condition notes matter most before you buy airbag module hardware, because a module still holding old crash data looks no different from a clean one. A module that has stored crash data, or came from a crashed car, must be properly reset or replaced by a specialist, never just have its warning light cleared. In particular, check these details of the listing:

• Photos: clear shots of the casing, the connector pins, and the part-number label.
• Seller reputation: a trader who deals in electronics with steady, recent feedback.
• Compatibility info: the hardware and software numbers checked against your car.
• Included components: the module on its own, or with the mounting bracket and plugs?
• Condition description: any crash history, corrosion, or burned circuits flagged.
• Testing/inspection: a note the module was read and is clear of stored crash data.
• Warranty and returns: cover if it will not code or turns up faulty.
• Shipping and packaging: anti-static wrapped and boxed so the pins survive.
• Documentation: which car it came from and whether it is virgin or reset.

If it reads clean and codes to your car, buy from the seller on their marketplace.

An airbag control module cost is not a single figure: it depends on the car, the SRS generation, and how common the module is. Expect a used unit for a common car to be inexpensive, a rare or premium SRS unit to top the range, and newer VIN-coded modules to sit in between. On Parthunt24, you can bag yourself an airbag control module for as little as 5.00.The things that swing an airbag control module price:

• SRS generation: a newer system or VIN-coded module raises the airbag control module price.
• Rarity: a module for an uncommon model takes longer to turn up.
• Completeness: a unit that comes with its bracket and plugs is worth more.
• Condition: a virgin or properly reset module with no crash history holds its value.

Set the airbag control module prices against each other and the best-value unit stands out, so sorting by airbag control module price lands the best price.

The module commands every airbag, so a fault means checking the bags and belts it controls too. Do not sign off the repair until the airbag warning light is out and the SRS is read with a scan tool. You’ll want to check these parts too:

• Passenger airbag: the front bag the module fires, and a common reason to check the system.
• Seat airbag: the seat-mounted side airbag the module controls.
• Seatbelt: the module also triggers the belt pretensioners, so check these too.
• Side airbag: the module fires it in a side impact, protecting the chest.
• Steering wheel airbag: the driver's front airbag, on the same SRS circuit.
• Door airbag: fitted in the door for side-impact cover.
• Curtain airbag: unrolls down the windows to cushion the head.

A used airbag control module must be virgin or resettable and coded to your car, not just the right part. Finding a suitable one for your vehicle can easily swallow up a Sunday afternoon, but it doesn’t have to.
