A fault code names a symptom, never a cause · review
LAIVIYA OBD2 reader with 2.8-inch color screen review
The cheapest way to stop guessing at a warning light: engine codes, freeze frame and live data on a color screen, with a battery voltage test thrown in — and no access to ABS or airbag, which the maker states plainly.
The last word The honest entry point. It does the engine, it says so, and it costs less than a diagnostic hour.
What lands on the bench
A handheld reader with a 2.8-inch color screen that plugs into the diagnostic socket and reads the engine control unit: stored codes, pending codes, freeze frame, live data and I/M readiness monitors, plus a battery voltage check.
What it reaches, and what it does not
The engine, and nothing else. The maker publishes a database of 35,901 code descriptions, which sounds like coverage and is not — it is the dictionary the tool prints from. A warning light that comes from ABS, airbag or transmission produces nothing here, and that is the honest limit of this price tier.
The feature that earns its place
Live data. Watching coolant temperature, engine speed and fuel trim while the engine runs is what separates “the code says oxygen sensor” from “the sensor is reporting something the engine is actually doing”. At this price, it is the reason to choose a screen over a plain code reader.
What is not published
Update terms. Nothing in the listing says whether the code database is updated, or for how long — for a tool at this price it is reasonable to assume the answer is no.
Availability
Listed but with no offer on the American Amazon store — the reference exists there and nobody is currently selling it.
Prices and availability are what Keepa reported on the date this page was updated; both move.
What it does, and what it misses
Strengths
Reads, clears and graphs live engine data at a price where most tools only read codes
The maker states the protocol count and the code database size rather than implying coverage
A battery voltage test on the same tool, which is the second thing you want when a car will not start
Compromises
Engine system only — a light coming from ABS or airbag is invisible to it
No service reset functions, so an oil-service counter still needs another tool
The 35,901-code database is a list of descriptions, not a measure of what the tool can reach

The questions that reach us
Will it turn the light off?
It clears engine codes, and the lamp goes out with them. If the condition that set the code is still present, both come back on the drive cycle that detects it.
Does it work on any car?
On any car with EOBD, which means petrol sold in the EU from 2001 and diesel from 2004. The maker states compatibility with 99% of vehicles built after 1996 and nine protocols.
Our score
7.5/ 10
The honest entry point. It does the engine, it says so, and it costs less than a diagnostic hour.

Sources
Specifications: the manufacturer sheet for garage tools and the matching Amazon product page. Prices and availability: Keepa. Every figure on this page names its source.
Engine system only · 2.5 ft thick cable · no batteries needed · maker states ABS and airbag are NOT supported
The reader that has been on this shelf for a decade, and the one whose listing is most explicit about what it cannot do: the maker states in the first line that ABS, airbag and SRS codes are not supported.
Best for: The glovebox tool for an older car, where reliability matters more than features.
The tool where the update policy is the headline: LAUNCH states lifetime free updates on a four-system scanner with a touchscreen and seven service resets.
Best for: Someone who works on several cars, or on one car with an ABS light.
Engine system · LCD screen · full OBDII protocol set stated · plug and play
A plain, plug-and-play engine code reader whose selling point is protocol completeness — the maker names the protocols explicitly, which several tools at this price do not.
Best for: Someone who wants a reader in the glovebox that needs no phone, no app and no account.
