When you perform repairs on your car's ABS module or replace key parts of the ABS system, you often need to ABS bleeding. Of course, if you notice a low brake fluid level or abnormal brake pedal behavior, you might also want to consider whether air intrusion is the cause. So how do you bleed the ABS? Do you need any tools?
Of course, you can bleed the ABS without a car diagnostic scan tool, but this often requires complex steps such as removing the tire, and you may need the help of a professional repair technician, even if bleeding air from the ABS brake sounds like a relatively routine and simple maintenance task.
Bleeding ABS without Autel scanner is difficult for DIYers.
Therefore, it is very important to have a car diagnostic scanner that can bleed ABS air at this time. It can make the operation simpler and save you the trouble of finding a professional technician for repair. You can easily bleed ABS air at home. Let's take a look at how to use the Autel scanner to bleed ABS air.
The ABS (Anti-lock Braking System) is a hydraulic braking system that uses sensors on all four wheels to monitor tire rotational speed. If a tire is about to lock, the system modulates braking force by applying, maintaining, and reducing pressure, ensuring the vehicle maintains directional control and comes to a smooth stop during emergency braking.
ABS bleeding is the process of releasing air trapped in the pump and valves in the anti-lock braking system, allowing the brake fluid to circulate smoothly and thus restoring normal brake pressure and performance.
The ABS is a hydraulic braking system.
Using Autel scanner to perform ABS exhaust is equivalent to having a bridge to communicate with the ABS system, avoiding tedious manual steps such as tire removal, making the exhaust work more accurate and faster.
Bleeding ABS uses Autel MP808TS.
Not all vehicles can perform ABS bleeding, and not all Autel scanners can perform this operation. You can check whether your vehicle and the Autel scanner you prefer support ABS bleeding by clicking the link below:
Many of Autel's automotive diagnostic scan tools have ABS bleeding capabilities. The overall process may vary slightly depending on the Autel scanner model and the car brand. The following are general ABS bleeding steps:
Use the main cable included in the accessories to connect the scanner to the OBD port under the vehicle dashboard to ensure continuous ABS bleeding and ensure that communication will not be interrupted due to connection problems during the bleeding process.
After connecting the scanner to the vehicle, select the service function and click on brake exhaust to enter. Then manually select the vehicle brand, year and other information or use the automatic scanning function of the Autel scanner, which will greatly save your time.
The steps for each vehicle may vary. Here's a general guide. Select the Hot function and then the "Anti-lock Braking System" function. Follow the instructions on the Autel scanner screen to open the left front wheel exhaust valve and connect the oil-water separator to bleed the ABS. Repeat for the other three wheels.
Follow the instructions on the Autel scanner screen to bleed the ABS.
Check and confirm that no fault codes appear and complete ABS bleeding.
Note: During operation, strictly follow the instructions on the Autel scanner screen. Failure to do so may result in operational errors. During the ABS bleeding process, keep the ignition switch on but do not start the engine to ensure that the Autel scanner can communicate with the ABS system.
