Includes manufacturer-specific reset and teach procedures
Mine was a little over $200 IIRC and has saved me lot of time with manufacturer-specific issues already that my cheap OBD2 scanner would just say "no error codes"
Fast diagnostic speed
what does that $400 one do that a $40 doesn't? Unless i can hit a button the $400 one and it actually fixes the problem, otherwise, i can only imagine it has more codes for complex issues?
Are there cheaper options that can show all codes?
You buy it with the ability to scan generic OBD Codes and one make of your choosing for specific codes, and you can add future makes down the line as you need them for $60 each or so.
Covers a wide range of vehicles
Every manufacturer has their own file and uses different versions of it for different cars.
Ability to read airbag codes
This covers the things that make Malfunction inductor lamp turn on which is emissions related items.
Easy to use and inexpensive
Easy to use, inexpensive and used by several Z3 owners including myself.
