What is the el 50449 TPMS reset tool?
TPMS System Overview
TPMS stands for Tire Pressure Monitoring System, a system that monitors the air pressure in a car's tires. There are two types: direct and indirect systems. Direct systems use pressure sensors in each tire that send data to the car's computer, while indirect systems measure differences in wheel rotation.
When the system detects low tire pressure, a warning light illuminates on the dashboard. To reset this after, for example, a tire change, a tool such as the el 50449 TPMS reset tool is required.
