ABS Toyota Corolla

ABS (Anti-Lock Braking System) is required to prevent the vehicle's wheels from locking up during braking and skidding.

In general, this system eliminates the occurrence of uncontrolled skidding of the car during emergency braking. In addition, with the help of ABS, the driver can control the car even during emergency braking.

ABS works according to the following principle:

1. Sensors installed on the wheels, at the initial stage of braking, register the initial blocking impulse.
2. With the help of "feedback" an electrical impulse is formed, which is transmitted through an electric cable, this impulse weakens the efforts of the hydraulic cylinders even before the moment when slippage begins and the car's tires return to contact with the road surface.
3. After the rotation of the wheel is completed, the maximum possible braking force is again created in the hydraulic cylinders.

This process is cyclical, repeating many times. This ensures that the braking distance of the car remains exactly the same as it would be in a continuous lock, but the motorist does not lose control of the direction.

The safety of the driver and passengers is increased, since the possibility of skidding the car and driving it into a ditch or into the oncoming lane is excluded.

The car's ABS consists of the following parts:

• speed sensors, they are installed on the front and rear wheels;
• brake valves operating on the hydraulic principle;
• devices designed to exchange information between sensors and valves in a hydraulic system.

Thanks to ABS braking, even inexperienced drivers will be able to handle your vehicle. To do this, in a Toyota car, you just need to press the brake pedal all the way to the stop. It should also be noted that the road surface with a loose surface contributes to the fact that the car significantly increases the braking distance. After all, the wheels do not dig into the loose surface, but simply glide over it.

ABS is installed on foreign-made cars, for example, on Toyota Corolla models. The main essence of the action of this system is to maintain the stability and controllability of the car while reducing speed in the most optimal proportion. This is due to the fact that in the Toyota Corolla model, sensors “control” the speed at which each wheel of the car rotates, after which pressure is released in the hydraulic brake line.

In Toyota cars, the control unit is located near the dashboard. The principle of operation of the control unit is that it includes electrical impulses from speed sensors located in the wheels of the car.

After processing the electrical impulse, the signal is sent to the actuator valves responsible for anti-blocking. A special electronic module constantly captures and monitors the performance of the entire ABS system. If any malfunction suddenly occurs, a light on the instrument panel lights up, thanks to which the driver learns about the breakdown.

In addition, the ABS system allows you to generate and store a fault code. This will greatly facilitate the repair at the service station. Toyota Corolla is equipped with a diode that warns of a breakdown. Also, a special photodiode signal may flash from time to time. Thanks to him, the driver learns that some "breakdowns" of operating parameters are possible in the ABS complex.

To correct the failure of settings and parameters, it is necessary to check whether the wires coming from the sensors to the electronic unit are well connected, the condition of the fuse and the fullness of soot related to the main brake cylinder are also checked.

Even if after all these operations the warning signs continue to flash, then the ABS system is faulty, and the owner of the Toyota Corolla car should contact a specialized service center.

So, car ABS components from a Japanese manufacturer. The anti-blocking block consists of:

1. 1. Hydraulic pump.
   2. The case, consisting of several cavities, is equipped with four magnetized valves.

In the drive cavity of each individual wheel, the necessary pressure is created and, if necessary, adjusted. Wheel rotation sensors provide signals that cause cavity valves to open and close. This block is located under the engine compartment cover of the Toyota Corolla.

Then comes the next assembly of ABS parts. These are high speed wheel sensors. They are installed on the "steering knuckles" of the front and rear wheels of Toyota vehicles. The sensors send a special pulse to the ABS main electronic module all the time.

The anti-lock braking system on Toyota cars is quite reliable and easy to operate and maintain. However, even the most reliable system on the most reliable Japanese vehicles requires regular maintenance and repair.
