It connects the trailer's ABS electronic control unit (ECU) to the power and diagnostic circuits, providing a convenient way to activate fault-code blinking without needing a separate diagnostic tool. It is typically replaced when the original harness is damaged by road debris, corrosion, or when the diagnostic switch becomes faulty, preventing the reading of ABS fault codes.
