Any K Line I have ever seen is 0-12 v square wave on any make or model. There may be some exceptions but that's Mini to Nissan an more that I have done.

Yes I do have 12v. Matt Herold below posted up some good info. I wasn't getting a square wave but now I see it was because I didn't have the scanner hooked up communicating at the time.

Mike- According to Alldata with ignition switch on; "battery voltage" Coincides with Calebs observations.
