1 / 6Zmoon ZM201 OBD2 Scanner with 2.8-Inch Color Screen
Inch Color Screen: The Zmoon ZM201 is a corded OBD2 code reader for engine diagnostics, with code reading and clearing, live data, freeze-frame information, and readiness checks. It is limited to engine systems, so it is not a substitute for a scanner that diagnoses ABS, SRS, transmission, or other vehicle systems.
At a glance
- Reads and clears engine fault codes and can retrieve VIN information, according to the listing.
- Live data with graph view, freeze-frame data, I/M readiness, O2 sensor tests, onboard monitoring, and EVAP checks are listed features.
- The listing describes a color display with adjustable brightness and light and dark modes.
- The scanner draws power from the vehicle's OBDII port, so the listing says it needs no separate battery or charging.

What to know before buying
Listing details to confirm
Vehicle coverage is stated inconsistently: the title says vehicles after 1996, while listing details give differing EU start years of 2001 and 2002, and the broad compatibility claim does not align with a separate note excluding hybrid and electric vehicles. Confirm the specific vehicle and OBD2 support before buying. The listing also promotes a battery test in one feature panel, but its detailed feature descriptions focus on engine diagnostics and do not clearly establish the scope of that function. Temporary codes may be cleared, while persistent or permanent codes can require repair and applicable clearing conditions.

Who is it for?
A good fit for
- DIY owners who want to read engine codes, review live data, and check readiness on a compatible OBD2 vehicle.
- Buyers who prefer a stand-alone, vehicle-powered reader rather than a phone-based scanner.
Less suited to
- Anyone needing ABS, SRS, transmission, TPMS, or full-system diagnostics.
- Owners of hybrid or electric vehicles, or vehicles whose OBD2 compatibility is uncertain.

Customer feedback highlights ease of setup, screen clarity, instructions, and engine-code reading, while also reporting mixed experiences with vehicle connections and whether all errors are detected. Those concerns matter because the ZM201 is specified for engine-system diagnostics and vehicle compatibility varies. The reported feedback is not a guarantee that it will connect to or identify every issue on a particular car.
Positive themes
- Customers describe the reader as easy to use and set up, with a clear display and straightforward instructions.
- Customers report useful engine-code reading and clearing.
Mixed feedback
- Compatibility feedback is mixed, with some customers reporting connection problems with their vehicles.
- Accuracy feedback is mixed, including reports that the scanner did not detect every error.
