XTOOL D9S Automotive Diagnostic Scanner: features, specs and who it suits

The XTOOL D9S is a professional-style car diagnostic scanner built around a 9.7-inch tablet. It reads trouble codes, shows live data and, depending on the vehicle, can send commands to modules and perform coding and reset procedures. XTOOL presents it as an upgrade of the D9 for professional mechanics, garages and advanced home users.

Bidirectional control

A basic code reader only reads. A bidirectional scan tool can also command parts of the car to act. XTOOL lists active tests such as turning the radiator fan on and off, the A/C clutch, the fuel pump, windows and mirrors, interior and exterior lights and the horn. These tests help confirm whether a component works without taking it apart. XTOOL notes that functions vary by vehicle, so check compatibility before buying.

Topology map

The intelligent topology map shows how a vehicle's modules communicate in one view. You can open a module from the map, see its information and view live data as graphs. XTOOL says this speeds up full-system diagnosis, though it notes the map isn't available on every vehicle.

Coding, programming and services

The D9S supports ECU coding for brands such as Mercedes-Benz, BMW, VW, Audi and Skoda, and offline module programming (PMI) for Ford, Lincoln and Mazda. It lists more than 42 service functions, including oil reset, electronic parking brake, steering angle sensor, throttle, battery management, ABS bleed, injector coding and crankshaft sensor relearn. Coding and programming change how a vehicle's modules behave, so follow the vehicle maker's procedures and the tool's prompts.

FCA AutoAuth

The 2024 version adds FCA AutoAuth for Chrysler, Dodge, Jeep and Fiat vehicles from 2018 onward, giving access to the secure gateway needed for diagnosis and bidirectional control. XTOOL says this works only with the VCI V208 version and needs an FCA account.

Hardware and connectivity

The tablet has a 9.7-inch screen, Android 10, 4 GB of RAM and 128 GB of storage. The battery is 6400 mAh at 7.4V. It connects by Wi-Fi, with a range XTOOL puts at more than 66 ft, or by USB cable. It supports the DoIP and CAN FD protocols used by newer vehicles, plus RP1210. The package measures about 21 x 14.6 x 6.3 inches.

Updates and support

Three years of software updates are included, with 14+ languages, including English, Spanish and French. XTOOL says it adds vehicle coverage and features irregularly. Technical support asks for the VIN and the tool's serial number.

Who it suits

It suits working mechanics, small garages and keen home mechanics who need more than code reading, particularly on European, Ford and FCA vehicles.

What to check before you buy

• Vehicle coverage: check your make, model, year and VIN against XTOOL's list.
• Functions: coding, resets and bidirectional tests vary by vehicle.
• FCA access: the AutoAuth feature needs an FCA account and the right VCI version.
• Updates: find out what happens once the three years end.
• Connection: check Wi-Fi availability near where you work.
• Know-how: coding can change vehicle behaviour, so be sure of the procedure.
