What is ABS bleeding?
ABS (Anti-lock Braking System) is a safety function that prevents the wheels of a vehicle from locking up when braking suddenly. It helps support steering control and vehicle stability during braking. It's a computer-controlled system that regulates brake pressure at each wheel, reducing the risk of skidding and loss of control.
ABS bleeding refers to the process of removing the air in the ABS (anti-lock braking system) hydraulic control unit, brake lines and other parts of the brake system. This process involves using a specialized tool to cycle the ABS pump and valves while bleeding the brake lines. This process helps maintain proper braking system performance and consistent stopping capability.
The function of ABS bleeding
Air bubbles can enter the braking system through system leaks, during maintenance or repair work, etc. When air bubbles are present, they can cause the brake pedal to feel squishy, which may reduce braking effectiveness and affect stopping distance. Bleeding the ABS system can help restore normal brake pedal feel and support efficient brake operation. This process typically involves using a special scan tool to activate the ABS system's hydraulic pump while bleeding the brakes at each wheel to remove the trapped air.
ABS bleeding is typically recommended in the following situations:
① When ABS contains air
② Replace the ABS computer
③ Replace the ABS pump
④ Replace the brake master cylinder
⑤ Replace the brake cylinder
⑥ Replace the brake pipeline or brake fluid

How to use scan tool to bleed abs module?
Bleeding an ABS module with a scan tool typically involves using the scan tool to activate the ABS pump and valves while you manually bleed the brake system.
The general steps are:
① Connect the scan tool to the OBD-II port on the vehicle and follow the manufacturer's instructions to access the ABS module.
② Press "ABS Bleeding" or similar function on the scan tool to activate the ABS pump and valve.
③ First, manually bleed the brake system at the wheel with the furthest distance from the master cylinder, and then move toward the nearest wheel. Continue bleeding the brake system until air bubbles are no longer visible in the brake fluid at all four wheels.
④ Once the brake system is fully bleeding, press the "Stop Bleed" or similar function on the scan tool to deactivate the ABS pump and valve.
⑤ Finally, test the brake pedal feel and braking response.
How often should perform ABS bleeding? The frequency depends on the particular vehicle and its usage. It is commonly recommended to inspect and bleed the brakes periodically, depending on vehicle usage and manufacturer guidelines. to remove any accumulated moisture or air in the system that may affect braking performance.
It is important to note that bleeding the ABS system is a specialized task that should only be performed by a qualified technician with the proper tools and knowledge to reduce the risk of improper operation.
