i got my power pup today and plugged it in under the dash on my 06 and it wont turn on. then i plugged it into my 05 and it turned on and worked fine. is there a fuse or something i need to check? i took my test light and theres no power at the port on the 06 but the 05 had power whats going on? i borrowed my buddys powerpup 2 weeks ago to check codes and it was working then.
can anybody help?

Check the cigarette lighter fuse in the underhood fuse box. Dont ask my why the DLC (obd port) is run off of that fuse. :confused: :)

The 06's are using the GM LAN for powertrain now. I don't think the Power Pup designed for the 05's will work on the new GM LAN. The TECH II won't work on the 06's unless you have the CANDI module connected in line now.

Some of the Light Duty Techs on here can probably tell you more, but I think you need a different tool.
