"controller init failed" when attempting to read ECM, 2003 Mustang
Hey guys, like the title says, I'm attempting to read this ECM for the first time. After it prompts me to turn the ignition off for 3 seconds and then back on, I get the error "controller init failed". I'm using MPVI2+ and it's got the latest update. Any ideas?
