ABS Actuator Solenoid Circuit Inspection Procedure:

CIRCUIT DESCRIPTION
The solenoid goes on when signals are received from the Electronic Control Unit (ECU) and controls the pressure acting on the Wheel Cylinders thus controlling the braking force.

FAIL SAFE FUNCTION
If trouble occurs in the Actuator Solenoid circuit, the ECU cuts off current to the Anti-Lock Brake System (ABS) Control (Solenoid) Relay and prohibits ABS controls.
