Wide Range of Applications
The T300 PRO is suitable for vehicle types including: cars, trucks, passenger vehicles, diesel vehicles, motorcycles, boats, beach bikes and more.
Reading Vehicle Information
Automatic scanning connection — no need to manually select the brand or model. Reads VIN and identifies vehicle production year. Supports up to 9 different protocols for multiple vehicle brands:
- SAE J1850 PWM (41.6 Kbaud)
- SAE J1850 VPW (10.4 Kbaud)
- ISO9141-2 (5 baud init, 10.4 Kbaud)
- ISO15765-4 CAN (11 bit ID, 500 Kbaud)
- ISO15765-4 CAN (29 bit ID, 500 Kbaud)
- ISO15765-4 CAN (11 bit ID, 250 Kbaud)
- ISO15765-4 CAN (29 bit ID, 250 Kbaud)
- ISO14230-4 KWP (fast init, 10.4 Kbaud)
- ISO14230-4 KWP (5 baud init, 10.4 Kbaud)
Real-Time Data View
View 27+ real-time car data parameters at a glance, including: Numbers of DTCs, Fuel system A/B status, Calculated load value, Engine coolant temperature, Short/Long term fuel trim, Inlet Pressure, Engine Speed, Engine Water Temperature, Ignition advance angle, and more. Supports Review Data, Record Data, Playback Data, and Unit of Measure settings.
Engine Troubleshooting
Quickly read the car's faults and clear the engine fault light. OBD menu includes: Read DTC, Clear DTC, I/M Status, ECU Info, Live Data, Mode 6, O2 Sensor, Mode 8, Freeze Frame. LED indicators provide instant status: Green = No fault codes; Yellow = Pending DTCs present; Red = One or more problems exist.
Built-in 50,000+ Fault Codes
Quick lookup of fault code definitions with an easy-to-use DTC Lookup interface. Navigate using directional keys to enter any DTC code for instant definition.
I/M Testing
The I/M Status function checks the operation of the emission system on OBD II-compliant vehicles. Accessible via the dedicated I/M shortcut key for one-touch access. Displays readiness status for MIS, FUEL, CCM, CAT, HCAT, EVAP, AIR, O2S, HRT, EGR monitors for both "This driving cycle" and "Since DTCs cleared" conditions.
In-Vehicle Monitoring Test (Mode 6)
After repairing or clearing fault codes, the on-board monitor test allows access to specific component tests. The vehicle manufacturer assigns MIDs and CIDs for testing different systems and components, including exhaust gas sensor monitors with test values, min/max limits, and status.
OBD Voltage
When the vehicle appears unable to diagnose, the OBD voltage function checks the voltage of OBD pins to help find vehicle faults faster. Displays voltage and normal range for: BUS+(2Pin), CAN-H(6Pin), K-line(7Pin), BUS-(10Pin), CAN-L(14Pin), line(15Pin), VIN(16Pin).
Customized Shortcuts
Assign the F1 and F2 shortcut keys to the most commonly used functions. Available functions include: Read DTC, Clear DTC, IM Status, ECU info, Live Data, Mode 6, O2 Sensor, Mode 8, Freeze, Voltage waveform monitoring, I/M.
Connection Method
OBD II Scanning:Find the DLC port and connect the OBD cable to the car DLC.
Battery Diagnostics:Connect the OBD connection cable to the clamp cable; connect the red clip to the positive battery terminal and the black clip to the negative battery terminal.
