This EZ-Scan on-board computer II scanner includes the newly released controller area network protocol, allowing for more capability and flexibility to manage the diagnostic process. This protocol is currently being used in a variety of vehicles and will be the mandated protocol in all new vehicles by 2008. It collects data from your vehicle's on-board computer and supports multiple trouble code requests including generic codes, pending codes, and enhanced codes. It also displays readiness test status and O2 sensor tests.
