I have an AutoXray OBDII EZ-Scanner 4000 & AutoXray EZ Charge 200 accessory. This pro automotive scanner 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. It also includes a great AutoXray EZ-Charge 200 battery conductance tester accessory, with cables, original manuals, and a nice hard case to boot. The entirety original cost was over $200, so I will let the set go for $100 cash firm.
