Toyota 44050-33030 Actuator Assy, Abs & Traction

ABS is a system that is created to maintain the steerability, directionality and deceleration of the vehicle under severe braking forces and on most types of roads. It does this by watching how quickly each wheel spins around and managing brake line pressure to prevent them from locking up. The ABS system comprises the actuator assembly, which consists of the master cylinder, electric hydraulic pump, and four solenoid valves. The speed sensors are placed at each wheel and create electrical surges that indicate their rotational velocity. The ABS computer (ECU) is referred to as its "brain" found either under the dashboard or within the ABS actuator and it uses information given by wheel speed sensors to control hydraulic line pressure. These codes allow identification of malfunctions in the ABS system since they are stored in its computer. Whenever a problem occurs in the system, an ABS warning light will be illuminated and you can undertake certain processes so that you can search for these codes. After looking into it more deeply through diagnosing such trouble codes, jumping terminals on data link connector clears them out while depressing brake pedal repeatedly until they are overridden.

After diagnosis, clear the trouble codes by jumping terminals TC and CG on the data link connector, turning the ignition key ON, and depressing the brake pedal eight or more times within five seconds. Then, remove the jumper wire and check the indicated system or component for repairs.
