DTC code C0265:

Started seeing the ABS & Brake indicators on my cluster. Changed both hubs since they had many miles on them and I still get the same indicators intermittently. Local parts store reads a DTC C0265 suggesting a control relay problem.

I found this site which displays a repair procedure for correcting this error condition. (It's a bit difficult to watch- an over done production, but pretty much suggests cracked solder joints that you can fix yourself):

Anyone experience the same with their brake controller? Pulling/cleaning the ground connection seems logical given the age of the truck. But could this really be as simple as resoldering a couple of joints?
