Zmoon ZM301 OBD2 Scanner Car Code Reader — 50,000+ DTC Library, Live Data & VIN Retrieval

Compact and built for DIYers and small shops, the ZM301 combines core OBDII functions with helpful shortcuts, cloud-friendly reporting, and broad vehicle coverage. It connects to any standard 16-pin OBDII port and delivers live stream graphs, freeze-frame capture, VIN retrieval, and battery voltage checks — all on a rugged, easy-to-use device with a built-in DTC library.

How quickly can ZM301 identify and clear engine fault codes?

The ZM301 reads stored, pending, and freeze-frame Diagnostic Trouble Codes (DTCs) and shows definitions from its 50,000+ entry database. After diagnosing, you can clear codes and switch off the MIL (check engine light) when faults are resolved. This accelerates basic repairs and helps confirm if further diagnostics are needed.

• Reads and clears stored/pending codes and freeze frames
• Displays DTC definitions from 50,000+ entries
• Turns off MIL/check engine light after clearing codes
• Retrieves VIN and I/M readiness status

What live data and testing features does it provide?

ZM301 streams live sensor data and can graph multiple PID values for clearer interpretation of issues. It supports battery voltage checks, O2 sensor tests, and onboard monitoring for common subsystems. The device also provides a simple performance test mode for basic acceleration and power checks.

• Real-time data streaming with graphing display
• Battery voltage and O2 sensor tests
• Onboard monitoring and component testing options
• Performance test (acceleration/braking distance and power proxy)

How does ZM301 simplify reporting and sharing results?

The scanner produces freeze-frame screenshots and DTC playback you can convert to QR codes for quick saving or printing with your phone. This cloud-printing approach reduces paperwork and makes it easier to share diagnostics with customers or mechanics. It’s particularly useful for documenting intermittent faults and repair records.

• Generates QR codes from live data and freeze frames
• Mobile-friendly screenshot scanning for instant reports
• Reduces manual entry and simplifies repair documentation
• Helps communicate findings with repair shops or customers

Which vehicles and users is the ZM301 compatible with?

ZMOON ZM301 works with the vast majority of gasoline and diesel vehicles that use the OBDII standard: U.S. cars (1996 and newer), many European models (2002+), and most Asian vehicles (2008+). It requires a standard 16-pin OBD2 port and is not designed for hybrids, new-energy EVs, or non-OBD2 protocols. Review your vehicle’s port and model year before purchase.

• Compatible with ~98% of OBDII-equipped vehicles
• Not suitable for hybrid or new-energy electric vehicles
• Requires a 16-pin OBDII diagnostic connector
• Ideal for cars, light trucks, and SUVs using OBDII

Who is this for: The ZM301 is aimed at home mechanics, automotive technicians in small shops, and fleet operators who need a dependable, no-frills scanner to read and clear codes, capture live data, and create shareable diagnostics. It’s useful for anyone who wants a faster first-pass diagnosis, to document repair needs, or to upgrade from an older basic code reader without investing in a full dealer-level tool. The package includes a canvas storage bag and is backed by a 60-day return window plus a three-year replacement service for added peace of mind.
