Circuit Description
WARNING: This page is about a different car, the 2003 Toyota Tundra, 2002 Toyota Tundra, and 2001 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.
This solenoid turns on when signals are received from ABS ECU and controls pressure acting on calipers/wheel cylinders, thus controlling braking force. If malfunction occurs in actuator solenoid circuit, ABS ECU cuts off current to ABS control relay and prohibits ABS control.
