The Zurich ZR4 Code Reader is designed for service writers and weekend mechanics. This tool is compact, convenient and quickly reads and clears trouble codes and lights. The ZR4 features an option to display in either English or Spanish, and displays 20 data points at once on a 2.8" color screen. Users can view freeze frame data, and a patented health monitor LED helps make it simple to check for emissions readiness. The hot key feature allows access to the menu with one-touch functionality.
