Engine/Transmission (1998.5 - 2002) Scan tool protocol 2001.5

[parnold1]

Just gought a ProScan tool. I got it to hook upand read our gasoline Yukon, but not the Dodge. Its is an 01. 5, 5 speed, 5. 9. I have a choice of protocols and several other perameters built in to the software. I am not sure of the correct ELM protocol. Anyone with experience with this tool?

Thanks
