Question about Cars & Trucks
ABS/& Red brake light staying on full time on Instrument Cluster (along with annoying buzzer). Plugged Tech II scanner in and "No Comm" comes up. I can get data from other modules, had code U1041 and others.

SOURCE: abs codes co281 & co265
the first of the two codes is for the brake light switch, the one that is under the dash attached to the brake rod and brake peddle. Not much to diag on that one, if its bad it's bad, and when it sets the code that means it's bad.
The second one is for the abs modual, it's under the truck on the drivers side. It is bolted to the top of the thing that has all of the brake lines going to it. MOST all of the time that code is set the modual is bad. It can be a little hard to get the bolts out they are torqs 20 or 25(i'm getting old). There are four of them holding down the modual. There are also a couple of connectors going to it. And some of the time it will blow the fuse for the abs under the hood(its in the underhood fues block). Make sure to clean off the modual before you pull it out. You don't want dirt getting in the solinoids for the BPMV(that's the thing it's bolted to).
