XTOOL D5 OBD2 Scanner and Reset Tool: features, specs and who it suits

The XTOOL D5 is a handheld car diagnostic tool. It plugs into a vehicle's OBD2 port, reads fault codes from four systems and performs a set of service resets. XTOOL aims it at home mechanics, DIY enthusiasts and small workshops who want more than a basic check-engine reader.

What OBD2 and a code reader do

OBD2 is the standard diagnostic connector fitted to cars sold since the mid-1990s. A scanner reads diagnostic trouble codes (DTCs) that the car's computers log when they detect a fault, and shows live data from sensors. XTOOL says the D5 works with OBD2-equipped vehicles built after 1996 and covers more than 90 vehicle brands, including minivans, SUVs and 12V diesel trucks. It lists support for the CAN FD protocol and FCA AutoAuth.

Four systems: engine, transmission, ABS and SRS

Many basic readers only check the engine. XTOOL says the D5 also reads and clears codes in the transmission, ABS (anti-lock braking) and SRS (airbag) systems. It shows live data in graphs or text, up to four values at once, such as fuel trim, O2 sensor voltage, RPM and coolant temperature. XTOOL notes some vehicles may show only three systems because the engine and transmission control are combined.

A warning from the brand is worth repeating: if a light or code comes back after clearing, the underlying fault has not been fixed. Clearing codes is not a repair. For airbag and brake systems especially, follow the vehicle manual and a qualified technician's advice.

The nine reset functions

XTOOL lists nine resets, including electronic parking brake (EPB) reset, steering angle sensor (SAS) calibration, battery management system (BMS) reset, throttle body relearn, TPMS reset, ABS bleeding, injector coding and oil service reset. These are the jobs usually needed after maintenance, such as new brake pads, a battery replacement or an oil change. XTOOL cautions that functions are not available on all cars and advises checking compatibility first. It also says that clearing transmission codes does not include transmission reset functions.

Screen, storage and updates

The tool has a 5.45-inch touchscreen at 1440 x 720, silicone grips and 32GB of built-in storage, expandable with a memory card. XTOOL says software updates arrive over WiFi, and describes them as lifetime updates. Tools like this need their vehicle database refreshed over time to keep up with new models.
