BYD Airbag Module Crash Data Reset Service – Atto 3, Dolphin, Seal, Seal U, Sealion 7, Tang

Clear stored crash data from your original BYD SRS / airbag control module — plug & play, no coding, no dealer

Which BYD Models This Covers

BYD Atto 3, BYD Dolphin, BYD Seal, BYD Seal U (and Seal U DM-i), BYD Sealion 7, BYD Tang and BYD Han — all model years sold in the UK and Europe. If your model isn't listed, call us with the part number on the SRS module label and we'll confirm.

Symptoms & Fault Codes

After any collision — even a minor bump that deployed a seatbelt pretensioner — the airbag module locks with crash data stored and the SRS warning stays on, which is an MOT failure. Typical codes:

• B0051 / B0052 / B0053 — Deployment commanded / crash event stored
• B00A0 – B00A6 — Pretensioner or airbag deployment loop faults after an event
• "Crash data stored" / "Airbag control unit locked" — shown by most diagnostic tools
• SRS warning light permanently on after accident repair

What We Do

We read your original module on the bench, clear the stored crash events and hard-fault memory, restore the module to its pre-crash state and verify it. Your own module goes back into the car, so it stays matched to the vehicle — no VIN coding, no dealer programming, no replacement module needed. Deployed airbags, pretensioners and seat sensors must of course be replaced before the light will clear.

Reset vs New Module

A new BYD SRS module from a dealer, coded to the car, typically costs several hundred pounds plus a long wait for parts. A crash data reset of your original unit is a fraction of that with a 1–2 day turnaround.
