Porsche automobiles have always been know as state-of-the-art, and often are seen as difficult to work on and diagnose by non-technicians and owners alike. Now there is a way to diagnose your Porsche just like the factory-trained technician does at the dealership! The durametric diagnostic tool is a software suite that installs on your pc laptop and hook to your car's data port and can read and communicate with the Porsche dme. It allows you to reset service reminders, read and reset diagnostic trouble codes, display and log actual values in real time, and turn off the check engine and airbag lights (and tell you why they are on in the first place). The durametric diagnostic tool can communicate with the engine dme, factory alarm system, airbags, seat memory system, abs, climate control, tiptronic automatic transmission, and many more systems that are hard-wired together in the car. This tool is different from the generic obd2 readers that are only able to diagnose emission-related issues. Included is the software and a usb cable to hook your laptop to the data port in the car. For use with laptops running windows 2000 or xp and microsoft net framework 1.1, 256mb of memory, 25mb of hard drive space. Note: some capabilities not available for older models (not able to display actual values and live data in '97 and older Porsche models) '96 and older models need a round adaptor to hook to car data port, sold separately.
