So my ABS light, traction control light and brake light came on, they conti nued to turn on and off some short others long periods of time. It has been cols and snowy so I thought maybe it was just some moisture somewhere, I p ut it in a heated shop all day. I should add that everything was still work ing even though the lights were on. I had it scanned and of coarse nothing showed up. I talked to some mechanics and they said check all the grounds a nd connections to the module, I also unhooked the battery checked fuses. I made sure all the connections were clean and put dielectric grease on the m, hooked everything back up and started the truck. This is where it gets g ood, every single possible light on the dash turned on from service air ba g, 4 wheel drive, stabilitrak, abs, traction control etc. I hooked the scan ner up and it said no power train connection and module 2 3 and 4 not respo nding. Then all my gauges went dead, truck still running but every light f lashing. Im sure it could be the module but I don't wanna just start guessi ng. I talked to a GM tech and he thinks it's something with wiring not t he module. Can anybody help me has this happened to anybody else
