ABS W/Vehicle Skid Control (VSC)

CIRCUIT DESCRIPTION

DTC Detecting Condition:

This relay supplies power to each ABS solenoid. After the ignition switch is turned ON, if the initial check is OK, the relay comes on.

Fail safe function:
If a trouble has occurred in the ABS solenoid 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.
