My ABS, Traction, and BRAKE lights are on on my dash so I hooked up the Tech 2 to it and it said Lost Communication with the EBCM. Does anyone know why or anything on this?? I have removed all the OnStar modules and wiring and disconnected the factory autolevel and have the brakes on it but I dont think thats the culprit of the Communication Error. Thanks guys

 

Clear the coded and drive it. I have had many false communication codes.

 

i have done that and no fix
