Brake Fluid Pump Relay: Description and Operation
CIRCUIT DESCRIPTION
The ABS control (motor) relay supplies power to the ABS pump motor. While the ABS is activated, the ECU switches the ABS control (motor)
relay ON and operates the ABS pump motor.
Fail safe function:
If trouble occurs in the ABS control (motor) relay circuit, the ECU cuts off current to the ABS control (solenoid) relay and prohibits ABS control.
