Question

2005 Chevrolet Silverado 2500HD 6.0L with engine code U1071, mechanic says the loss of communication w/ EBCM, What's that?

Answer 1

Hi there

The EBCM is the electronic brake control module. The abs unit in this case. The main computer is not communicating with the brake computer. This results in the code. This could be an issue with the communication line or a problem with the brake control module.
