Re: Lots of errors on check engine light
Did you have any aftermarket alarm or stereo installed recently?
I would say you have a bad ground somewhere or your FCM is bricked to cause BUS communication issues like that.
Please kick down the panel under the steering wheel and see if there are any broken, clipped wires, or there are any loose fuses.
