The ABS and VSC are designed to give vehicle maneuvering ability, and maintain the car's course and the ability to decelerate at the maximum rate during hard braking and on different types of terrains. ABS helps avoiding that wheels lock during heavy braking as it regulates brake line pressure according to wheel speed, while VSC supports the traction control. The actuator assembly consists of electric hydraulic pump and solenoid valves for the production of hydraulic pressure for the braking system and on the other hand speed sensors at the wheel sends data to the ABS ECU. Cameras at the front are installed on the steering knuckles Both rear sensors are also dissimilar between the AWD and 2WD variants. Yaw rate and acceleration sensor provides information on pitch of the vehicle in the case of emergency stop. In the ECU, information coming from the speed sensors is used to regulate hydraulic pressure and identify problems, which is signified by an ABS light on the car's dashboard. However , if the warning light continues to glow, it is recommended that before getting a professional service, the following tasks should be performed; To execute component removal, one has to disconnect the battery and then take off the air filter housing. The ABS actuator is located after removing the brake line fittings and using bolts to remove the actuator bracket. Front and rear wheel speed sensors need the car to be lifted, wheels to be dismantled, and some wiring harness disconnected for replacement of the sensor with this being unique for 2WD and AWD cars.
