what is the protocol for the ecm at the obdII port
I am trying to decide on a code scanner and want to make sure that one that I choose can read and diagnose and be compatibility.
If it is for a Jeep you will have to buy the higher end units like the innova 3160 or 31403 for it to do everything like ABS, SRS, OBD, and even then sometimes they won't thoroughly do SRS and you still wind up at the dealer.
I have the Innova 3160 and like it pretty well. It will read lots of live data.
