The D8 immediately connected to the car network, and presented several codes. the interface was great, and easy to click through the problem codes to get advanced diagnostic data, live and freeze frame data from the car canbus network, and help to use my skills to find and fix the root cause.
The battery control computer was found faulty, and with some digging and visual inspection I was able to replace the part, and my Prius was back on the road.
Since that time the D8 has helped me find problems in many cars and Trucks. from resetting transmission 'learning' mode to smooth out shifts, properly bleeding abs brakes, to adjusting fuel pressure and A/F ratios on light diesels. Even Identifying the notorious VTEC solenoid issues in Honda engines and Shift Errors in later GM truck transmissions. (Change the fluid often!)
This tool has paid for itself many times over with advanced diagnosis saving the typical Parts Cannon Approach to fixing todays sophisticated automotive systems. While I am not a professional shop, I am considered by many friends and famiy to have advanced mechanical skills, with over 40 years of auto repair experience.
In short, this is a very sophisticated tool that should definitely be added to any serious enthusiast toolbox. It has programmed keys and remotes for several cars, which alone is savings well beyond the purchase cost. I have paid a lot less for other tools, only to find they were worth it by doing a lot less.
My only 'challenge' is that I wish I had bought the wireless option, but that is on me.
Xtool has provided excellent customer support with software updates to cover all the latest developments in tech, as well as help me better understand how to use the equipment.
I thought quite a bit about spending this much on a tool for my issues, and look back and consider one of the value purchases I have made.
TL,DR: Great Product. Great Value! Amazing Customer Service.
