Ok here we go . My 07 quit running out of the blue. We were off roaring and some I think some wires came loose behind the aftermarket radio. The pays light is blinking code 15, I have checked fuses relays and also had a mobile mechanic one take a look. Hooked up his fact scanner and said it couldn’t communicate with a module...the pats I am assuming.So preceded to dig deeper and pulled stereo out, more than just one wire was loose. I also took pcm out to have it tested and it was good. I have the small plug of the two for the stock stereo still attached.There is a splice in the light blue/and pink wire and another splice on the tan wire.I have traced them out to be canbus+ and canbus- and have no idea where to even start. Pleeeeeease someone help me....
