ABS W/Vehicle Skid Control (VSC)

CIRCUIT DESCRIPTION

DTC Detecting Condition:

ABS motor relay supplies power to the ABS pump motor. While the ABS (& BA & TRAC & VSC) are being activated, the ECU switches the motor relay on and operates the ABS pump motor.

Fail safe function:
If a trouble has occurred in the ABS motor relay circuit, the ECU cuts off the current to the ABS solenoid relay and prohibits the ABS (& BA & TRAC & VSC) controls and the brake system becomes normal.
