XTOOL D5S OBD2 Scanner - 16 Resets & CAN FD Diagnostics

Our review of the XTOOL D5S finds it best suited for DIY mechanics and small shops that need a capable, affordable OBD2 scanner with advanced reset functions. The D5S stands out for its combination of full OBD2 diagnostics and a wide set of 16 reset functions, plus CAN FD and FAC AutoAuth for newer vehicles. In practice it reads and explains engine, ABS, SRS, and transmission codes, displays live data in text or up to four PID graphs, and performs relearns and resets that would otherwise require dealer tools or separate devices.

Key Features

• 16 Reset Functions: Provides high-demand service functions like EPB reset, Throttle Body Relearn, BMS battery reset and TPMS reset to support common maintenance tasks.
• Full OBD2 Diagnostics: Reads DTCs for Engine, Transmission, ABS and SRS and shows live data including fuel trim, O2 voltage, RPM and coolant temperature to help pinpoint faults.
• CAN FD and FAC AutoAuth: Supports modern vehicle protocols and AutoAuth for better compatibility with newer models and systems.
• Live Data and Graphing: Displays real-time parameters in text or up to four PID data graphs for clearer diagnosis of intermittent issues.
• One-Tap WiFi Updates: Free lifetime updates via WiFi keep the tool current without subscription fees, and 32GB of storage holds diagnostic records.
• Portable Design: A 5.45 in high-resolution touchscreen plus silicone grips make the unit easy to handle during shop or home use.

Who It's For

The D5S is ideal for home mechanics, DIY enthusiasts, and small repair shops that want more than a basic code reader but are not ready to invest in dealer-level equipment. Its mix of full OBD2 scanning, live data, and 16 service resets covers most routine maintenance and troubleshooting needs for cars and light trucks.

Those who need extremely deep manufacturer-level coding or dealer-only features should look elsewhere, and users should check vehicle compatibility beforehand since AutoVIN and some reset operations may not work on every make or model.

Pros & Cons

Pros

• Comprehensive reset list including EPB, SAS, BMS and throttle relearn for common service tasks.
• Clear live data with up to 4 PID graphs helps diagnose misfires, sensor faults and electrical issues.
• Supports CAN FD and FAC AutoAuth for better coverage of newer vehicles and protocols.
• Free WiFi updates and ample storage make it a good long-term value.

Cons

• AutoVIN may not identify all vehicles and some resets can be vehicle-specific, so compatibility checks are necessary before purchase.
• Not a substitute for dealer-level programming for certain proprietary modules on some brands.
