ABS(Anti-Braking System) will play a crucial role in enhancing the safety as the system ensures that even under hard braking, none of the wheels get locked. This gives the driver better control over the vehicle as s/he can steer the vehicle around an object and avoid impact. ABS also reduces braking distance significantly, both in dry and wet conditions.

So after replacing ABS components, we need to initialize related ECU info.



Note:

Keep ignition ON and make sure that ECU battery is full. The tool I use for initialization is Topdon Artipad.



Steps:

1. Choose the correct car models. You can choose your car model correspondingly. The theory is all the same.

2. Choose the correct system: ABS-service function-Initialization

3. Choose the correct option: “After replacing ECU or related components”

4. And the display prompt specific operation: keep car stay still and horizontal. Keep wheels aligned, release brake paddle.

5. Then the ESC initialization is done.

6. If the tool detects G sensor, it will re-calibrate. And this is the reason why we need car to stay horizontal.

7. And the tool will detect if ESC system was installed, if yes, need to turn ignition OFF and ON again.

8. From here are a little bit complicated steps, start the engine first and drive at 3-15mph, turn around at least 90 degrees. ESP indicator will flash till the process finishes.

9. Step on brake paddle and turn steering wheel to the very left, and then very right, and very left again, then to the center.

10. Drive at 3-15mph, turn around at least 90 degrees and drive for another 50 inches, stops, keep driving to see if screen prompt test succeed.

11. Now need to clear steering info in ECU, stop the engine but leave ignition on and top on TES on screen.



Finally, the ABS initialization is done, comparing to other maintenance, this procedure is rather complicated, so maybe ask a technician to do this for you is also a good option, but it’s always good to know what would a technician do to your car.
