BYD Airbag Module Crash Data Reset by Post UK – Atto 3, Dolphin & Seal SRS Light
BYD Airbag Module Crash Data Reset by Post – Atto 3, Dolphin & Seal SRS Light
After a collision — even a relatively minor one — your BYD's SRS airbag module records the impact event as permanent crash data. From that moment on, the module locks itself in a fault state: the SRS warning light stays on, and the entire airbag and seatbelt pretensioner system is disabled until that crash data is professionally cleared. The car has not forgotten, and no amount of clearing codes with a generic OBD reader will resolve it — the data is written at a deeper level than standard diagnostics can reach.
At The Vehicle Check, we reset BYD SRS airbag modules by post from anywhere in the UK. Whether you drive an Atto 3, Dolphin or Seal, you post us the module, we clear the stored crash event data, bench-test the unit, and return it with free tracked delivery — usually within 3 to 5 working days. No dealership waiting lists, no eye-watering replacement quotes, no new module to code in.

Why Is the SRS Light On in My BYD After an Accident?
The SRS light is on because your airbag module has logged a crash event it cannot clear by itself. BYD's SRS control module — like those used across the wider automotive industry — is designed to store impact data as a permanent record the moment airbag deployment thresholds or pretensioner triggers are met. Even if the airbags themselves did not physically deploy (a minor shunt can still trip the sensors), the module registers and locks the event. Until a qualified technician with the right equipment accesses the module at data level and performs a proper crash data reset, the SRS system will remain disabled. This is not a software quirk; it is an intentional safety architecture to ensure the module is inspected after every incident.
Does TVC Support BYD Atto 3, Dolphin and Seal Airbag Modules?
Yes — TVC's crash data reset service covers the SRS airbag modules fitted to the BYD Atto 3, BYD Dolphin and BYD Seal. These models have established a significant presence on UK roads since their mainstream arrival, and we have invested in the tooling and data coverage needed to work on their SRS systems accurately. If you are unsure whether your specific build date or module variant is covered, call us on 0203 489 2610 before you post — we will tell you straight.
Why Choose a Mail-In Service Over a BYD Dealer for Crash Data Reset?
A BYD dealer's default response to an SRS fault after a crash is almost always to quote you a replacement module — new part, programming costs, and labour on top. That route routinely runs into several hundred pounds, and lead times on EV-specific modules can stretch for weeks depending on parts availability. Our mail-in service sidesteps all of that. You remove the existing module (or have a local garage pull it for you — usually a quick, inexpensive job), post it to us, and we reset and return it. The module that goes back into your car is your original unit, data-cleared and ready to protect you again. For the vast majority of BYD owners we deal with, this costs a fraction of the dealer replacement route and gets the car back on the road faster.
Because BYD ownership in the UK is still relatively new, many independent garages and even some franchised dealers lack the specific tooling for BYD's SRS architecture. TVC operates as a dedicated automotive electronics specialist — not a general garage with a laptop — so BYD airbag module work receives the same focused attention as the DSG mechatronic, Mercedes transmission, and clutch actuator work we are known for. You can see our wider electronics offering across mechatronic repairs, clutch actuator repairs, and BCM, BSI and FRM services.
How Do I Send My BYD Airbag Module to TVC?
The process is straightforward and safe when you follow a few simple steps:
- Disconnect the battery first. Turn off the ignition, disconnect the negative terminal, and wait a minimum of 20 minutes. This allows residual capacitor charge in the SRS system to dissipate. Do not skip this step.
- Locate and remove the airbag module. On most BYD models it sits beneath the centre console or under the front seat area. If you would rather not remove it yourself, any local garage can do this quickly — you only need to send us the module, not the vehicle.
- Wrap it carefully. Place the module in an anti-static bag if you have one, wrap it in bubble wrap, and box it securely. Use a sturdy cardboard box with adequate padding on all sides. Avoid loose packing that allows the unit to move in transit.
- Send it tracked and insured. Use Royal Mail Tracked 48 or a courier service with signature confirmation. Include a note with your name, contact number, vehicle registration, and a brief description of the incident.
- Address it to: The Vehicle Check, Office 13, 25 Mollison Avenue, Enfield, EN3 7NJ.
We process modules in the order they arrive. Once your BYD airbag module is reset and tested, we return it via free tracked delivery — no hidden postage charges on the way back.
What Is the Turnaround Time for BYD Crash Data Reset?
Standard turnaround is 3 to 5 working days from the date we receive your module. In many cases we turn work around faster than that, but 3–5 days is the reliable window to plan around. We will contact you once the reset is complete and the module is dispatched back to you.
Is the Reset Permanent and Does It Carry a Warranty?
The crash data reset is permanent in the sense that the stored impact event is fully cleared — the module no longer holds a record of the previous collision. The SRS system is restored to a fully operational state. All crash data reset work completed by TVC is backed by our standard warranty. If the SRS light returns as a result of any issue with our reset work rather than a new vehicle fault or sensor problem, we address it at no additional cost.
