The ABS pump is located near the firewall in the car's engine compartment. The working principle of the ABS pump is: relying on highly sensitive wheel speed sensors installed on each wheel and the vehicle's speed sensor, under computer control, when emergency braking is detected and a wheel is about to lock up, the computer immediately commands the pressure regulator to release pressure from that wheel's brake caliper, allowing the wheel to resume rotation. The ABS pump, also known as the Anti-lock Braking System, features anti-skid and anti-lock characteristics. Its working process involves a cycle of locking and releasing, keeping the vehicle in a state of near-lock rolling, effectively overcoming issues like deviation, side-slip, and fishtailing during emergency braking, and preventing loss of vehicle control.

What to Do When the Sunroof Won't Close and Automatically Retracts?

If the sunroof won't close and automatically retracts, you can open the cover next to the sunroof switch, where you'll find basic tools to manually close the sunroof in an emergency. Alternatively, check the sunroof's sliding tracks for any obstructions. If the issue is caused by debris, simply remove it to restore normal operation. Below is an extended explanation: 1. Removing interior fog: The car sunroof can quickly eliminate fog inside the vehicle. Although the weather is already hot, many regions experience continuous rain, making the car interior prone to fogging. In such cases, opening the sunroof along with the side windows allows air circulation, preventing fog formation. 2. Lowering interior temperature: Additionally, the sunroof helps rapidly reduce the car's interior temperature. During summer when parked outdoors under direct sunlight, the car becomes extremely hot, making it difficult to enter. Many drivers believe turning on the air conditioning is the fastest way to cool down the interior, but this isn't true. The quickest method is to open the windows while driving, which will quickly lower the interior temperature within a short distance.

Is It Normal for Oil to Be on the Shock Absorber Rod?

Oil on the shock absorber rod is not a normal phenomenon. Leakage in a car's shock absorber is a very dangerous issue. If the shock absorber is leaking oil, you can still drive normally, but the shock absorber will lose its damping effect, reducing comfort. At high speeds, this can affect the vehicle's stability. More information about shock absorbers is as follows: Function of shock absorbers: The shock absorber is a major component of the suspension system, supporting the vehicle's weight. Additionally, it plays a crucial role in improving the smoothness and comfort of the ride. The hydraulic mechanism inside the shock absorber significantly absorbs vibrations caused by uneven road surfaces, greatly reducing the bumps experienced during driving. Structure of shock absorbers: A shock absorber is not a completely sealed cylinder. The hydraulic oil inside is sealed by rubber gaskets. Over time, the hydraulic oil can seep through these gaskets due to prolonged pressure, resulting in oil leakage from the shock absorber. Shock absorber oil leakage is a very slow process, and it only affects the driving experience when the leakage reaches a certain level.
