International Prostar Traction control on when brake.

Hello, it is 2009 prostar with ISX and Eaton automatic, problem is that I can’t select any gear, when I push brake pedal and push D or R truck makes 3 time beeping Noise and still stays at N, like I never hold brake pedal and Traction Control light comes on, no brake light comes on when I push brake pedal. I got new pressure sensor (brake sensor) and replaced it, no brake light still. But when I use paper clip and connect to contacts of brake sensor connector together I here relay click and lights on. Truck engine starts good, no problem. Any suggestions? Thx.

 

today checked all battery terminals, cleaned it, no change. Also have error code - bodycontroler brake sensor signal erratic every time I push pedal

 

Thank you fore response. Can you tell me in to which port of body controller brake pedal switch go? J5 or J4 and is it same color wires ?

 

Ok today I made my best, I was able to track brake switch contact from sensor to cab controller (orange) but what interesting that second (grey) wire had resistance with few wires back at cab controller plug, (unless orange and grey go to different port of cab controller It is looks weird) or may be that is my problem. I still have my stop lights perfectly working when that clock is off, as soon as egnition on, problem starts.
