Looking for some advice on this one. When cold, this unit will have inoperative 8 ways. Before it came to me, the steering wheel switch was replaced and the bcm was swapped with another unit. The problem remains. With the problem occurring, using DLB, I can activate all the amber and red warning lights. What's strange is while looking at the inputs on the signal menu, I do not see any change while operating the activation switch. How ever if I switch to the connector view, it does show activity while activating the switch.
I have some codes that come and go with the problem in both the ecm and the brake control module. Ill update that info tomorrow. I just wanted to throw this out there to see if any one had run into something similar or if any one had some advice. Thanks guys!

I have some more info on this problem. When you crank the engine over it sets a dtc 1215: remote throttle signal can error and a 2545 ECM not recieving body can messages. Also in the brake module its setting a J1939 time out message and a code for an open brake light signal circuit. I checked the data lines for propper voltage and resistance and it looks ok. same with the brake light circuit, every thing seems to work ok when I check it.
Any body have any sugestions on where to go with this or how to nail down the problem? Im running out of ideas.
