Brake Fluid Pump Relay: Description and Operation

CIRCUIT DESCRIPTION
The ABS motor relay supplies power to the ABS pump motor. While the ABS (or TRAC) is activated, the ECU switches the ABS motor relay ON and operates the ABS pump motor.

Fail safe function:
If trouble occurs in the ABS motor relay circuit, the ECU cuts off current to the ABS solenoid relay and prohibits ABS (and TRAC) control.
