Section 06-09B: Brake, Anti-Lock, 4-Wheel | 1996 Bronco Workshop Manual |
The main relay (14N089) is located in the power distribution box.
The main relay has two functions. First, when the relay is energized, it supplies power to the six solenoid valves in the anti-lock hydraulic control unit assembly and the pump motor relay coil. Second, when not energized, it supplies ground to the amber ABS warning light. The main relay is controlled by the anti-lock brake electronic control module and is energized when it receives a ground on Circuit 599 (PK/LG).
