All of us study something new while we work collectively. Keep me updated on your development and in case you want any greater information. Gm is receiving some of lower back trailer brake manage modules (tbcm) and trailer brake relays that are completely functional. The tbcm video display units the voltage of the electrical brake wire (darkish blue circuit forty seven) that runs from the trailer brake relay to the 7-pin trailer connector within the bumper. If the voltage on this cord is shorted decrease or higher than the designed output voltage of the relay the tbcm will set a dtc.
The wiring concerns i have determined were corrosion issues near where the harness connects to the tbcm and where humans have spliced in for 5th wheel hitches. We get sodium chloride placed on our roads inside the wintry weather and it truly affects connections if they may be made poorly. Look at the whole legnth of the cord from the front to lower back. Pull the internal fender at the left side front to look into the harness. There are a few sharp edges which can reduce into the bottom of the harness and cannot be seen from the top.
