I just finished reading the diagnostic repair procedure for your issue and I am afraid your only choice for repair is to go through a repair facility that has the proper scan tool to diagnose your problem....your truck apparently does have the BCM module and it monitors all of the brake systems, so your issue could be anywhere from a short to a bad switch, sensor or BCM.....the repair sequence has 14 separate steps to diagnose the problem and unfortunately you need the proper scan tool to do it.....
