WHY THIS PAGE EXISTS

Compatibility first, product second.

VeroRoad does not treat a generic feature list as proof that the function works on every vehicle. Tier A means the stored manufacturer evidence explicitly reaches model-year + tool/family + function; engine, trim and VIN are still separate qualifiers unless named.

BUYING CHECKLIST

Before checkout

  • Confirm the exact year, model and market.
  • For high-cost tools, verify VIN, engine/trim and the target module in the vendor's current coverage checker.
  • Check required adapters, subscriptions and software version.
  • Use the evidence score as a shortlist aid — not as a replacement for a live OEM/vendor coverage check.
COMMON QUESTIONS

2021 BYD Song PLUS DMI Throttle relearn FAQ

Which scan tool should I buy for this job?

Start with the highest evidence score above. A lower-priced tool can be the better purchase when it has the same documented vehicle/function support and you do not need the extra capabilities of a premium platform.

Does a Tier A match cover every engine and trim?

No. Tier A on this page means explicit model-year + tool/family + function evidence. Engine, trim, VIN, module and region are only exact when the source names those qualifiers.

Why does VeroRoad link to Amazon?

VeroRoad keeps compatibility evidence separate from shopping. Purchase buttons route to Amazon.com; VeroRoad may earn a commission from qualifying purchases without changing the compatibility ranking.
