Thinkcar Platinum 391 10-Inch OBD2 Diagnostic Scanner - Full System Scan Tool with Maintenance Reset Functions

The ThinkCar Platinum 391 is a 10-inch professional diagnostic tablet built for independent repair shops, dealer-alternative shops, and advanced mobile technicians who need OE-level coverage on modern domestic, Asian, and European vehicles. It runs the new TCOS platform on Android 10 and supports CAN 2.0, CAN FD, DoIP, and J2534 Pass-Thru, which are the four protocols you actually need to talk to 2020-and-newer ECUs, gateway modules, and high-speed networks. The kit covers 120+ passenger vehicle makes out of the box with three years of free software updates, and adds optional packages for electric vehicles (70+ brands) and heavy duty trucks (150+ brands) if your shop sees those categories.

Diagnostic Functions

The Platinum 391 reads and clears DTCs across all available control modules, not just powertrain. It pulls live data with on-screen graphing, runs bi-directional active tests, performs VIN identification, and supports OBD2 and EOBD compliance testing on most 1996-and-newer vehicles. Topology mapping gives you a visual layout of every module on the vehicle network so you can see which controllers are online before you start chasing a no-communication code. ADAS calibration is supported on the software side, though physical calibration frames and target boards are sold separately. TPMS service is supported, with optional sensor programming tools available if your shop needs them.

Maintenance Resets and Special Functions

The tool includes 42 maintenance and service reset functions, covering the work that keeps a service bay billable: oil light reset, electronic parking brake release, throttle body relearn, steering angle sensor reset, battery registration, DPF regeneration, injector coding, ABS bleeding, gearbox adaptation, headlamp matching, A/F sensor reset, sunroof initialization, suspension calibration, and seat memory reset, among others.

Online Programming and ECU Coding

Online programming on the Platinum 391 is the feature that separates this tablet from sub-$1,000 scan tools. It supports online programming functions for Audi, BMW, Hyundai, Jaguar, KIA, Land Rover, Mercedes Benz, Nissan, Porsche, Renault, Seat, Skoda, Subaru, Volkswagen, SAIC-MG, Maxus, Trumpchi, Sprinter, and Honda. ECU coding lets you program replacement modules, adapt new components after replacement, and complete the post-repair steps that used to require a trip to the dealer.

Software, Updates, and Remote Support

Three years of free software updates are included from the date of activation. After year three, software renewal is offered as an annual subscription. Activation requires a one-time WiFi setup using the device serial number. Dual video remote diagnostics is built into TCOS so a remote technician can see the vehicle, the live data, and your screen at the same time, which is useful for less common European procedures or when you want a second opinion on a tough drivability case. Supported interface languages include English, French, Spanish, German, Russian, Italian, Japanese, and Portuguese.
