It connects the ABS electronic control unit (ECU) to wheel speed sensors and modulator valves, enabling the trailer’s ABS to function correctly. Harnesses can degrade from corrosion, chafing, or road debris, leading to ABS fault codes or loss of anti-lock braking. Replacing a damaged harness restores proper ABS operation and helps meet safety inspection requirements.
