Brake control module

Wheres this module on a peterbilt 388, and how to test it? Has a code something like "cant find abs module" , i think it was spn 1481

From what I can tell this is an issue between the cab controller and the abs module on the J1939 datalink. I would think you could follow an abs sensor wire to the module and then check the typical power/ground and then your canbus wires. Don't seem to be a lot of info about this error out there.

Unplugged brake module and plugged back in and everything is working again...
