just a little nervous
from what i have read the jb4 can clear most codes without the bt tool...can it clear all the codes that are relevent to warranty?
im about to buy jb4 and wondering if i should purchase the usb cable with it or not. Do i need the bt tool to keep my warranty? thanks Mike |

If you are nervous about warranty issues either don't buy it or do more research. IMO, it's always good to have a BT tool to get codes and details.

The JB4 has code reading built in via dash or laptop. The USB cable is for your free firmware updates. Highly suggested. No need for BT.

if you decide to go with the jb4 i think it would be a smart idea to grab the bt tool. i think the usb cable for the jb4 is for updating the firmware
 . the best thing to do is do a lot of research because there is a lot of of tunes out there.
