Expert ScoreRead review

The XTOOL D8S is an 8-inch diagnostic tablet built around one feature most tools at this price skip: topology mapping. Instead of scrolling through modules one at a time, it draws a color-coded tree of the vehicle’s network so you can see which module is faulting and how it connects to everything else. You also get full bidirectional control for active tests like injector firing, ABS pump cycling, and EVAP checks, plus 42+ reset services and pre/post scan reports. It handles CAN FD on 2020+ GM, DoIP on BMW and JLR, and FCA AutoAuth on 2018+ Chrysler, with three years of updates.

XTOOL D8S Bidirectional Scan Tool — Topology Mapping, ECU Coding, 42+ Reset Services

Description

  • Color-Coded Topology Mapping: Scans every available module and renders the results as a network tree, showing which units are faulting and how they communicate. This is the D8S’s main differentiator over the older D8, though XTOOL notes topology isn’t supported on every make.
  • Full Bidirectional Control: Commands components directly rather than just reading their codes — injector tests, ABS motor pump cycling, EVAP tests, A/C clutch and window actuation, idle relearn, fuel trim reset. XTOOL advertises over 4,000 active tests across supported vehicles.
  • 42+ Reset Services and Ford PMI: Covers oil, EPB, BMS, SAS, DPF, throttle, and A/C relearn among others. The PMI function lets you copy configuration data from an original module to a replacement unit on Ford, Lincoln, and Mazda vehicles.
  • Protocol Coverage for Newer Vehicles: Supports CAN FD for GM 2020 and newer, DoIP for BMW E/F/G chassis plus Jaguar and Land Rover, and FCA AutoAuth for Chrysler 2018+. AutoAuth requires registering an account through AutoAuth directly, which is a separate step from buying the tool.
  • 8-Inch Android 10 Tablet, 3 Years of Updates: Runs a quad-core 1.8GHz processor with 64GB storage and a 5000mAh fast-charging battery, with an 8MP camera, speaker, and microphone built in. Software updates run over WiFi for three years, and the interface supports 23 languages.
