The Thinkcar THINKSCAN PLUS S4 is a tablet-style OBD2 scanner that reads and clears codes in five systems: engine, transmission, ABS, SRS and body control. Its 5-inch screen, automatic VIN lookup and Wi-Fi updates make it easier to use than basic handheld code readers, which usually cover engine codes only. It suits DIYers and small shops that want multi-system diagnostics without a pro-grade tool. It is not a full bidirectional scanner: it reads and clears codes and shows live data, but it does not run active tests or service functions like some pricier rivals.

The Thinkcar THINKSCAN PLUS S4 is a handheld OBD2 scanner with a 5-inch display and a straightforward menu system. It reads fault codes from five vehicle systems: Engine (ECM), Transmission (TCM), ABS, SRS and BCM.
It looks up the VIN automatically. It also shows live data streams and I/M readiness status, and it supports oxygen sensor testing and on-board monitoring. Wi-Fi updates keep the diagnostic software current.
It works with vehicles from over 93 manufacturers, and with vehicles made after 1996 that use the OBD2 protocol.
