Meet the Autel AL539B: the 3-in-1 diagnostic tool that goes beyond basic code reading. It’s the ultimate upgrade for the DIY mechanic or car enthusiast, combining the power of a professional OBD2 scanner, a precision battery tester, and a built-in multimeter (AVOmeter).
Comprehensive Vehicle Coverage
Designed for most cars from 1996 onwards—whether American, Asian, or European—this scanner delivers in-depth analysis and reliable diagnostics right at your fingertips.
Advanced Battery & Electrical Testing
Quickly and accurately assess the health of most 12V batteries, including AGM, standard, and maintenance-free types. The integrated multimeter lets you check voltage, continuity, and current with ease, making electrical troubleshooting straightforward.
Full OBD2 Diagnostic Power
Take full control of your vehicle’s health. Read and clear trouble codes, view live data and freeze frame information, check I/M readiness, and perform O2 sensor tests. One of its most valuable features? It can turn off the check engine light by clearing the fault codes after repairs are made.
Efficient & User-Friendly
Speed up your diagnostics with DTC lookup for detailed code definitions, data playback, and print capability. This helps you track your vehicle’s condition over time and make informed decisions.
