ABS Main Relay: Description and Operation
The combination relay is by the control module. It has two relay circuits, both controlled by the control module. The combination relay supplies power to
the hydraulic unit solenoid valves and controls the hydraulic pump. The relay also has two built-in diodes. One diode eliminates the power surges
induced when the pump motor cuts out, the other switches the ABS warning indicator on if the combination relay is not on or the control module is
disconnected.
