T400 Elite 3-in-1 Scanner | Professional OBD II, Battery & Component Diagnostic
The T400 is a professional-grade diagnostic platform featuring an ultra-clear 3.5-inch high-brightness display. It is designed to be the only tool a modern workshop needs, seamlessly integrating OBD II scanning, advanced battery diagnostics, and component-level testing.
With an upgraded visualization interface and a database supporting over 1,400 special functions, the T400 delivers rapid responses and high-accuracy results that far exceed the capabilities of a basic how to test a car battery with a multimeter search.
Three-in-One Professional Power
1. Full-System OBD II Scanning: Access comprehensive engine diagnostics, including Mode 6 and Mode 8 tests, O2 sensor monitoring, and real-time data streaming. The built-in DTC Lookup and Cloud Printing features allow you to generate and share professional test reports instantly.
2. Advanced Battery Health Module: Move beyond simple voltage. The T400 supports a massive range of standards (CCA, DIN, EN, etc.) with a testing range of 20–2000 CCA. It performs dedicated Load Tests, Charge Tests, and Startup Tests to evaluate the battery, alternator, and starter motor in one workflow.
3. Precision Component Testing: This tool bridges the gap between a scanner and an oscilloscope. It features specialized modules for Fuel Injector inspection/cleaning, Relay testing, and Signal output, allowing you to identify exact component-level faults.
Core Capabilities for Professionals
Visual Waveform Monitoring: Track real-time voltage fluctuations and signal outputs on the high-resolution 480 × 320 screen to catch intermittent faults.
Massive Vehicle Coverage: Supports all major OBD II protocols and is compatible with 12V and 24V systems (8–24V supply range), covering cars, motorcycles, and light-duty trucks.
Workshop Efficiency: Includes OBD Voltage Detection and TYPE-C firmware upgrades, ensuring your device remains compatible with the latest automotive technologies.
