Brake Fluid Pump: Description and Operation

CIRCUIT DESCRIPTION
The ABS & TRAC motor relay supplies power to the ABS & TRAC pump motor. While the ABS is activated, the ECU switches the ABS &
TRAC motor relay ON and operates the ABS & TRAC pump motor.
Fail safe function:
If trouble occurs in the ABS & TRAC motor relay circuit, the ECU cuts off current to the ABS & TRAC solenoid relay and prohibits ABS control
and TRAC control.
