leagend has strengthened its OBD II scanner portfolio with the release of leagend MS300 OBD II Trouble Code Diagnostic Tool

NEW YORK, NY, UNITED STATES, July 13, 2025 /EINPresswire.com/ -- In today’s fast-paced automotive service industry, swift and accurate diagnostics are vital for maintaining workshop efficiency and customer satisfaction. leagend, a leader in automotive diagnostic equipment and battery management solutions since 2005, has strengthened its OBD II scanner portfolio with the release of leagend MS300 OBD II Trouble Code Diagnostic Tool—a reliable, user-friendly device designed to streamline engine code reading, clear faults, and support proactive maintenance workflows.

Addressing Workshop Pain Points in Engine Diagnostics
Dealership service bays and independent workshops frequently grapple with time-consuming diagnostic routines, especially for complex engine-related issues. Traditional scanning tools can be slow, provide limited data, or lack integration. leagend MS300 meets these challenges head-on, offering technicians a quick and efficient means to read and clear trouble codes, check inspection readiness (I/M status), and access vehicle identification data for more accurate troubleshooting.

Key Features of leagend MS300
Read, Clear, and Reset Engine Codes: Instantly identify faults and quickly reset the Malfunction Indicator Lamp (MIL) to improve customer-facing service times.

View I/M Status: Supports inspection and maintenance readiness checks, reducing rework on annual inspections.

VIN Reading Capability: Extracts the Vehicle Identification Number directly from the ECU, aiding accurate service history and parts lookup.

Wide Protocol Support: Compatible with CAN, VPW, PWM, ISO9141, and KWP2000 — covering nearly all OBD II/EOBD vehicles.

Simple Display: Easy-to-read 2×8-character monochrome screen and intuitive navigation enable fast operation without deep menu dives.

Seamless Integration into leagend’s OBD II Ecosystem
leagend MS300 strengthens a comprehensive OBD II diagnostic lineup that includes Bluetooth-enabled scanners, memory savers, colorful screen battery testers, and auto trip computers. leagend’s offerings—such as leagend BA570 and leagend BA670 combined OBD II scanner & battery tester—deliver multifunctional tools that combine engine diagnostics with battery status testing.

For shops handling battery maintenance alongside routine engine service, these hybrid tools can significantly reduce the time and cost of switching between devices. Fully featured Bluetooth scanners like leagend ELM327 and leagend BLE327 bring wireless convenience.

Who Benefits from leagend MS300?
Independent Auto Repair Shops & Dealerships: Rapid error code reading and reset functionalities enable quick service and optimal throughput.

Fleet Maintenance Centers: Integrated I/M status reading ensures vehicle readiness and avoids registration delays or inspection rejects.

Used Car Inspection Services: VIN retrieval simplifies vehicle checks and can instantly verify service histories, saving time and effort.

Mobile/Pop-Up Service Technicians: Compact, durable, and battery-powered, leagend MS300 is ideal for roadside diagnostics and emergency breakdown services.
