Tool comparison
Autel MaxiSys is a widely used range of Android-based professional diagnostic tablets, from the MS906 up to the flagship Ultra. Paired with a Bluetooth or wired VCI, it performs full-system diagnostics — DTC read/clear, live data, bi-directional controls, ECU coding and adaptations — across most makes, plus service resets such as oil, EPB, SAS, DPF, TPMS and, on some models, immobiliser functions. Higher models add J2534 pass-thru ECU programming, topology module mapping and integrated scope and inspection cameras. General repair shops and diagnostic technicians use MaxiSys as an all-round OE-level scan platform. Autel provides subscription software updates that expand coverage and add newer coding and programming functions.
ThinkDiag is a compact Bluetooth OBD-II dongle from Thinkcar that turns a phone or tablet into a full-system diagnostic scanner through its app. Unlike basic ELM327 dongles it provides manufacturer-level coverage — reading and clearing DTCs across engine, ABS, SRS, transmission and body modules, showing live data and running a set of reset functions such as oil, EPB, SAS and throttle — with software licensed per vehicle brand or by subscription. DIY enthusiasts and mobile technicians use it as a portable alternative to a full scan tablet. Function depth depends on the purchased software packages and on the specific vehicle being worked on.
Autel MaxiSys (Aftermarket Diagnostic Scanner, Autel) and ThinkDiag (Aftermarket Diagnostic Scanner, Thinkcar) compete in the same space, so the choice comes down to coverage, workflow and price for your specific ECUs.
