Integrated Electronic Brake (IEB) System Air Bleeding

In case of IEB replacement, perform the air bleeding procedures.

1. Disconnect the negative (-) battery terminal to turn off IEB ECU.
2. Refill the reservoir to MAX (upper) level line.

   Brake fluid:  DOT 4

3. Set the air bleeding tool (SST: 09580-3D100) and the cap of SST (0K585-E8100) to reservoir tank and make pressure (3 bar) to it.
4. Lock the bleed screw after stepping on brake pedal 10 - 20 times in condition of break fluid has been drained out for 10 seconds after opening each bleed screws (A).

   Tightening torque: 

   Front air bleeding screw (Mando 18 inch): 13.7 - 19.6 N.m (1.4 - 2.0 kgf.m, 10.1 - 14.5 lb-ft)

   Front air bleeding screw (Continental 19 inch): 11.8 - 17.7 N.m (1.2 - 1.8 kgf.m, 8.7 - 13.0 lb-ft)

   Rear air bleeding screw: 6.9 - 12.7 N.m (0.7 - 1.3 kgf.m, 5.1 - 9.4 lb-ft)

   NOTE:

   • To improve the work efficiency bleed the air in the following order: FR → FL → RL → RR.
   • If the brake fluid goes below 'MIN' while working, remove the pressure feeder and mount the pressure feeder after filling the brake fluid in the reservoir.
   • Repeat the procedure for wheel in the sequence shown below until air bubbles no longer appear in the fluid.
   • Be careful not to open the bleed screw too much as the air may get inside the pipe.

5. Remove the air bleeding tool carefully.
6. Refill the reservoir to "MAX" level line.
7. Connect the negative (-) battery terminal to turn on IEB ECU.
8. Perform the "Fluid Circulation Mode" by diagnostic tool following in the order below.
   1. Connect self-diagnosis connector (16 pins) located under the driver side crash pad to self-diagnosis device, and then turn the self-diagnosis device after key is ON.
   2. Select the "Vehicle model" and "ESC" on diagnostic tool vehicle selection screen.
   3. Select the "Fluid Circulation Mode" on diagnostic tool screen, then select OK.
   4. Proceed with the test according to the screen instructions.

   5. Detach the diagnostic tool after "Fluid Circulation Mode" is done.
9. Disconnect the negative (-) battery terminal to turn off IEB ECU.
10. Refill the reservoir to MAX (upper) level line.

    Brake fluid:  DOT 4

13. Remove the air bleeding tool carefully.
14. Refill the reservoir to "MAX" level line.
15. Connect the negative (-) battery terminal to turn on IEB ECU.
16. Repeat the above procedure if air leaking process has not done properly after the procedure is done.
