About this item

The T300Pro is a 3-in-1 tool that reads and clears engine fault codes, runs a 6-mode test on your 12V battery and charging system, and checks ECU wiring through a breakout circuit — all in one compact device. It covers full OBD2 functions like live data, freeze frame, I/M readiness and VIN lookup, shown on a 2.8-inch color screen with graphing and record/playback. Just plug it into the OBD2 port — no app, no extra battery — and it works on most gasoline cars from 1996 onward plus 12V motorcycles.

All-in-one T300Pro: OBD2 code reader, 6-mode 12V battery tester and 16-pin ECU breakout tester combined, so you skip buying three separate tools
Reads and clears engine trouble codes with a 30,000+ DTC database, plus live data, freeze frame, I/M readiness, O2 sensor test, EVAP leak test, VIN lookup and MIL status
Battery and charging analysis covers SOH, SOC, CCA, internal resistance, cranking performance and alternator voltage, compatible with flooded, AGM, EFB and GEL 12V batteries
Breakout circuit mode helps trace ECU communication faults, loose wiring and port power problems that standard scanners miss
2.8-inch color screen shows live graphs of RPM, coolant temp, fuel trim and O2 voltage, with record and playback to compare readings before and after a repair
Plug-and-play, no app or external battery needed; works on OBD2 gasoline vehicles from 1996+ (US), 2001+ (Europe), 2008+ (Asia) and 12V motorcycles, supporting ISO9141-2, KWP2000, CAN and SAE J1850 protocols
