Where is the ABS fuse located in the Ford Escort?

The ABS pump of the Ford Focus is located on the inner side of the car tires, and it can be seen by lifting the car. How ABS works: During braking, ABS quickly determines the wheel lock-up state based on the speed signals from each wheel speed sensor, closes the normally open input solenoid valve on the wheel that is starting to lock, and keeps the braking force unchanged. If the wheel continues to lock, the normally closed output solenoid valve is opened, and the braking pressure on that wheel rapidly decreases due to the direct connection to the brake fluid reservoir, preventing the wheel from completely locking due to excessive braking force. This keeps the braking state at the optimal point (slip ratio S at 20%), achieving the best braking effect and the highest driving safety. Classification of ABS: ABS is mainly classified by channels. In ABS, the brake pipelines that can independently adjust the braking pressure are called control channels. The control channels of ABS devices are divided into four-channel, three-channel, two-channel, and one-channel types. One-channel ABS: Also called single-channel ABS, it has a brake pressure regulator installed in the rear wheel brake master cylinder and a wheel speed sensor mounted on the rear axle differential (some have one on each rear wheel). Two-channel ABS: This type of ABS is difficult to balance in terms of directional stability, steering control, and braking performance, and is rarely used today. Three-channel ABS: It independently controls the two front wheels, while the two rear wheels are controlled together based on the low-select principle (i.e., both wheels are controlled by one channel to ensure the wheel with less adhesion does not lock), also known as hybrid control. Four-channel ABS: It has four wheel speed sensors, with a brake pressure regulator device installed in the pipeline leading to each of the four wheel brake cylinders, enabling independent control and forming a four-channel control system.
