Description
Most late-model cars have a USB charging port for smartphones and other devices. In older vehicles, many owners have added USB charging capabilities with cigarette lighter adapters powered by accessory circuits. USB charge ports are used frequently, and today’s techs need to know how to test, diagnose, and repair these systems. This video gives an overview of tools, techniques, and common problems for customer cars. With the right equipment, you’ll be able to test USB ports for voltage and amperage, check cables for connection issues, and even simulate a load on the charging system. Not all USB charging components are created equally, and because most customers are mixing and matching devices from different manufacturers, the right tools and techniques become essential for troubleshooting.
