Turned key, nothing happened. Test battery, tested good. Found a corroded and broken RED wire going into the if hub. Spliced in a new connector and plugged it in. Turned key, dash finally lights up but so does the red security light that flashes. Radio says "anti theft code, code error. Please restart the system" but no way to enter the security code(got it from alfaobd). Checked fuses for the ecu. Most read 3.4v on both sides with key in on position. Used alfaobd to connect to rf hub and finds 2 error codes. U1197 and u0100. So i clear them, read again, no faults found. Read the bcm in alfa, more error codes that have lost communication with xxxx module. Clear them, read again. Still present. Unplug rf hub, read bcm codes, clear them, read again, no faults found. Plug rf hub back in, more codes found in rf hub and bcm again. Decide to jump the run/start relay to force ecu to "wake up" and it works for 99% of my accessories and fuel pump and injectors and can start truck. Turn key to off position, truck stays running. I have tried to reset the ecu in alfa under engine, body computer and rf hub. I have ran the replace rf hub, enter security code. Says the procedure was successful. Go to run the multi modular handshake, procedure failed. I am at stumped. Ordered a new rf hub thinking when the wire broke, maybe it shorted the rf hub internally but not sure i would be able to connect to it in alfa if that was the case so now I am unsure if that will fix my problem. Any help appreciated
