Autel AC909 MAXIHVAC A/C Diagnostic Manifold System
From electronically controlled compressors to advanced heat pumps, modern vehicles demand diagnostic tools built for this new era - intelligent, connected, and precise. Step by step guided instructions for equipment hookup and the entire repair workflow Vehicle-specific overview of A/C specifications and locations, including compressor and refrigerant metering types A single screen workflow that incorporates HVAC live pressures and OBD sensor values, including blend door functionality and outlet temperature readings First A/C tool that will conclusively identify refrigerant leaks and/or excessive moisture Introducing the use of Nitrogen for a pressure leak test, system tightness test, and purge procedures for faster evacuation First A/C manifold gauge tool that decouples from the A/C lines while still monitoring low & high pressures Variable displacement compressors test by either OBD bidirectional commands and/or physical connection to the ECV valve while comparing live low & high side pressures on a single tool Large sight glass allows for visual inspection for excessive UV dye, oil contaminants, component failures caused by heat, and solid particulates Self-diagnostics to determine equipment efficiency, tightness, and accuracy
