DTC 21

DTC 21, 22, 23, 24 ABS Actuator Solenoid Circuit

CIRCUIT DESCRIPTION
This solenoid goes on when signals are received from the ECU and controls the pressure acting on the wheel cylinders, thus controlling the turning of the wheels.






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