(Works on any version of Windows, MacOS)


CAUTION: This is genuine v1.4b (same as latest 2.1) ELM327 scanner that uses Elm Electronics firmware. This is NOT a clone as is sold 99% of cases on eBay. How do you know it's a clone? It'll have these version numbers: v1.4a, v1.5, v1.5a.

Did you know that 99% of those cheap ELM327's on eBay (usually under $15) actually support half the data compared to High quality, genuine chip counterparts. Example, cheap eBay/Alibaba/AliExpress clones will NOT display or WRONGLY display data for: EVAP, O2 and HO2, B1S1 Lambda data parameters. While Total Car Diagnostics ELM327 cable fully shows their data in absolute accuracy. This is difference between being safe on the road — or not.

This Total Car Diagnostics ELM327 USB scanner works on 99.9% of today's cars — yes, even yours.

ELM327 USB plugs into your car and laptop (running Windows) — and let's them communicate with each other through OBD software.

Meaning you can diagnose vehicle problems, reset faults, tap into performance statistics — and basically see everything you ever wanted to know about the inside of your vehicle(s).

What's more - our scanner will give you "dealer level" diagnostic power on your vehicle — allowing you to perform advanced diagnostics, health checkups and fault analysis on systems beyond generic OBDII systems of just Engine and Transmission. (Yes, it supports manufacturer systems as long as your OBD software supports them too. But they all support Engine and Transmission.)

In addition, Total Car Diagnostics ELM327 USB scanner can read numerous car data/parameters that handheld scan tools can't. Combined with powerful OBD software — you'll be able to read up to 15,000 possible data parameters from you vehicle(s).



Before going forward, please first check that your car is OBD2 compatible. Because this ELM327 interface only works on OBD2 compatible cars. Click here to check car compatibility now. (Your car MUST be OBD2 for this to work.)
