Normal Operation
The trailer brake control module is provided voltage at all times by the battery junction box (BJB) fuse 17 (30A) through circuit SBB17 (RD). Ground
for the trailer brake control module is provided through circuit GD138 (BK/WH). The trailer brake control module receives voltage from the stoplamp
switch through circuit CCB08 (VT/WH) when the brake pedal is applied. When requested, the trailer brake control module sends voltage to the trailer
tow connector through circuit CAT19 (BU).
