Freestorm provides testing and repair support for common Airbag ECU and SRS control module faults across a wide range of vehicle makes &models.
If your airbag warning light is on, the module has stored crash data, or diagnostics show no communication or internal ECU failure, we can help assess the unit and manage the repair route where possible.
Airbag ECUs control essential restraint system functions.
The unit is assessed before repair is confirmed
A repair route may avoid unnecessary replacement
Typical turnaround from receipt of the unit, depending on the fault and testing requirements
Support with fault codes, part numbers or booking.
The Airbag ECU, also known as the SRS control module or airbag control module, is the control unit responsible for monitoring the vehicle’s supplemental restraint system.
It receives information from crash sensors, seat belt pretensioners, airbags and related safety components. In the event of a collision, the system decides whether restraint components need to deploy.
Because the Airbag ECU is linked to a safety-critical system, warning lights, stored crash data, internal faults or communication problems should be assessed professionally.
A faulty Airbag ECU may prevent the SRS system from operating correctly. Depending on the fault, airbags or seat belt pretensioners may not deploy when required, or the vehicle may continue to show an airbag / SRS warning light.
The warning light can also cause NCT / roadworthiness issues and should be investigated before further repairs are carried out.
Remanufacturing is a structured industrial process that returns used parts, known as cores, to reliable working condition through inspection, replacement of worn parts, rebuilding and testing.
For customers, this means a professionally remanufactured unit is not simply a used part. It is a component that has gone through a controlled process designed to restore performance, reliability and value.
Best when:
The original Airbag ECU can be tested and repaired, or crash data / internal faults can be addressed safely.

Best when:
The original module is severely damaged, corroded, burned, physically broken or cannot be repaired safely.

Repair is often the most practical first route, but it depends on the condition of the unit and the fault found during testing. If the module is too damaged to repair, we will advise on the next step.
Airbag ECU faults can appear in several ways. The exact cause may be the control module, crash data, wiring, sensors, seat belt pretensioners, airbags or related SRS components, so proper diagnosis is required.
Airbag / SRS warning light on
The airbag warning light stays illuminated on the dashboard or returns after clearing.
No communication with Airbag ECU
Diagnostic equipment cannot communicate with the SRS / airbag control module.
Crash data stored
The module may remain locked after an accident or airbag / pretensioner deployment
Fault code will not clear
The same SRS fault code returns immediately after being cleared
Intermittent SRS faults
The warning light appears randomly, often linked to internal faults, voltage issues, wiring or sensor communication
Non-start or related vehicle messages
Some vehicles may show additional messages or system faults when the airbag module cannot communicate correctly.
Fault codes vary by manufacturer, model and diagnostic tool. The examples below are common references only and should not be treated as a final diagnosis without testing.
Often linked to internal failure within the SRS control module.
Commonly reported on some Fiat Ducato, Peugeot Boxer and Citroën Relay Applications.
The vehicle cannot communicate with the airbag / restraints control module.
Reported on some Fiat / Alfa / Ford platform applications when communication with the airbag module is lost.
The module has recorded deployment or crash event data and may need professional reset / repair assessment.
Internal electronic failure can prevent the airbag ECU from communicating or operating correctly.
After an accident, crash data may remain stored in the Airbag ECU and prevent normal system operation.
The module may not respond to diagnostic equipment due to internal failure, power supply issues, damaged pins, wiring or network communication faults.
Moisture ingress can cause corrosion, short circuits or intermittent SRS faults.
Low voltage, jump starting, battery issues or damaged power circuits can trigger or contribute to airbag module faults.
Corrupted memory or stored data may cause warning lights, locked modules or faults that cannot be cleared normally.
Bent, damaged or corroded pins can prevent reliable communication with the Airbag ECU.
Before sending the unit, gather as much information as possible. This helps us confirm the correct repair route and avoid delays.
In many cases, repairing the vehicle’s original Airbag ECU can help retain the original coding and vehicle configuration. This may avoid the coding or VIN programming often required when fitting a brand-new or used replacement module.
However, programming requirements depend on the vehicle, the fault, the module type and the repair carried out. We will advise where additional coding, calibration or diagnostic checks may be required after refitting.
Airbag ECUs are safety-critical components, so every repair route must be handled carefully. Freestorm manages the testing & repair process with a focus on clear diagnosis, correct handling, careful packaging, communication and aftercare.
Typical repair route: 5-10 working days from receipt of unit.
Typical turnaround is approximately 5-10 working days from receipt of the unit, depending on the fault, testing requirements, repair complexity, parts availability and courier times.
We will keep you updated if additional time is required.
Complete the booking form with your vehicle, part number and fault details.
We confirm the next steps and provide delivery instructions. Pack the unit securely and include your booking details.
The unit is tested and repaired where possible. If the fault or condition means repair is not suitable, we will advise.
Your unit is returned with the relevant repair information and warranty details where applicable.
Freestorm can help with Airbag ECU faults across many common vehicle makes and models.
Audi
BMW
Ford
Mercedes-Benz
Volkswagen
Peugeot
Chery
Toyota
Volvo
Airbag ECUs are part of the restraint system, so the repair route must be handled carefully and professionally.
Where suitable, repairing the original module can be more practical and cost-effective than replacing it with a new or used unit.
We help review symptoms, fault codes, part numbers and vehicle details before confirming the next step.
From booking to return delivery, Freestorm keeps the repair route simple and organised.
Typical turnaround is approximately 5-10 working days from receipt of the unit, depending on the fault and testing requirements.
This depends on the part type. Send us a photo of the unit label or part number and we will confirm what is required.
We can often advise based on symptoms, fault codes and part numbers, but final confirmation may require testing.
Warranty terms depend on the part type and repair carried out. We will confirm the applicable warranty before or after the repair assessment.
Vehicle make, model, year, registration/VIN if available, part number, fault codes, symptoms and any diagnostic report.
Send us your vehicle details, part number, fault codes or symptoms and we will help identify whether Airbag ECU testing and repair is the right route.
