Fiat 500 SRS Airbag Module Crash Data Reset – Part Numbers 52040843 / A2C95530204

After a collision — even a minor one — the SRS airbag module in your Fiat 500 stores crash event data that locks the system and keeps the airbag warning light permanently on. The Vehicle Check offers a dedicated crash data reset service for Fiat 500 SRS modules carrying part numbers 52040843 and A2C95530204, with a straightforward nationwide mail-in process, 3–5 day turnaround and free tracked return. View the live listing here.

Why Is the Airbag Warning Light Still On After a Collision?

When your Fiat 500 is involved in a collision — whether the airbags actually deployed or not — the SRS module logs that event permanently in its internal memory. Scanners can read the fault, but they cannot erase it: the data is written at a hardware level and requires specialist equipment to clear. Until it is cleared, the SRS warning light stays on and the airbag system remains disabled, which is both a legal grey area and a genuine safety concern. Part numbers 52040843 and A2C95530204 are the unit-family identifiers associated with this service — check the label on your own module and TVC will confirm it is the right match before any work begins.

What Does the Crash Data Reset Actually Do?

The reset process wipes stored crash event data from the SRS module memory and clears the hard fault codes that prevent normal airbag system operation. Once complete, your module is restored to a pre-accident state: the airbag warning light is extinguished and the system is fully active again. This is distinct from replacing the module — your original unit is retained, which means no coding, no programming at the vehicle and no dealer involvement needed. TVC's engineers work on SRS airbag modules across a wide range of makes and have built up significant practical experience with Fiat group electronics. You can see the full range of crash data services available at thevehiclecheck.co.uk/collections/crash-data.

How Does the Mail-In Process Work?

Sending your module is straightforward. Remove the SRS airbag module from the vehicle — it is typically located under the centre console or beneath the dashboard — then pack it carefully using the steps below.

• Wrap the module in at least two layers of bubble wrap, paying attention to the connector pins.
• Place it in a rigid cardboard box with foam or crumpled paper packing on all four sides and underneath the lid.
• Include a note with your full name, return address, contact number and vehicle details (registration, make, model).
• Send via a tracked courier service — Royal Mail Tracked 48, DPD or similar — to: Office 13, 25 Mollison Avenue, Enfield, EN3 7NJ.
• Keep your tracking reference until you receive confirmation from TVC.

Turnaround is 3–5 working days from the day TVC receives your unit, and return delivery is free on a tracked service. The service is available to customers across the whole of the UK as well as internationally — the workshop is based in Enfield but the mail-in model means location is no barrier at all.

Is Mail-In Better Than Going to a Fiat Dealer?

Is This the Right Part Number for My Fiat 500?

Part numbers 52040843 and A2C95530204 are unit-family identifiers that appear across a range of Fiat 500 SRS modules. They are not necessarily exclusive to a single build variant or model year. Before you place an order, check the label on your own module and get in touch with TVC — either by phone or through the product listing — to confirm your unit is covered. TVC will not begin work until compatibility is confirmed. This protects you from sending a module that falls outside the service scope. Check the live listing and confirm your part number here.

TVC also handles a broad range of other automotive electronics including mechatronic unit repairs, clutch actuator repairs, and BCM, BSI and FRM module cloning — all available through the same straightforward mail-in process.
