Diagnostic code U1071
My 2005 Silverado 2500HD has CEL on with code U1071,
Lost communications with Electronic Brake Control Module.
Should I replace module or look for faulty wiring.
I assume this is for trailers with electronic brakes.
Don't know where the module is either. Thanks

i dont know where the module would be but id suggest looking for faulty wiring before you replace a module itll be a little cheaper. and if you dont use the trailor brake and thats what it is you should be able to just bypass it if you dont use it
