Brake Fluid Solenoid Valve Relay: Description and Operation
CIRCUIT DESCRIPTION
This relay supplies power to each ABS solenoid. After the ignition switch is turned ON, if the initial check is OK, the relay goes on.
Fail safe function:
If any trouble occurs in the ABS solenoid valve relay circuit, the ECU cuts off current to the ABS solenoid valve relay and prohibits ABS control.
