    TIp
    Ensure the vehicle is not charging.
  3. Remove the rear underhood apron. See Underhood Apron - Rear (Remove and Replace).
  4. Raise the vehicle and remove all four wheels. See Wheel Assembly (Remove and Install).
  5. Lower the vehicle to a working height.
  6. Locally connect a laptop with Toolbox 3 to the vehicle. See Toolbox 3 (Connect and Disconnect).
  7. Clean the area around the brake fluid reservoir breather cap and remove the cap.
  8. Add clean brake fluid to the full level in the bleeder reservoir.
  9. Add clean brake fluid to the MAX level in the reservoir.
  10. Install the pressure bleeder adapter onto the vehicle brake reservoir.
  11. Connect power supply to the bleeder tool, and then turn the bleeder tool on.
  12. Set the brake bleed reservoir pressure to 30 PSI, and then attach the brake bleed reservoir to the brake bleed adapter.
  13. Bleed the LH front caliper.
    1. Remove the LH front caliper bleed valve covers (x2), and then install the fluid catcher to the outer bleed valve.
    2. Open the outer bleed valve.
    3. In Toolbox, click on the Actions/Autodiag tab, and then search for "PROC_DPB_ESP_REPAIR-BLEED".
    4. Click PROC_DPB_ESP_REPAIR-BLEED, check ALSO_BLEED_ESP and select PHASE_1_RR_AND_FL_WHEELS, click Run to start the routine.
    5. Pump the brake pedal while the routine runs with an interval of 2/3 seconds between pressing and releasing the pedal.
      Informational PurposesAn informational icon, calling your attention
      Note
      Initially, the brake pedal should feel soft. After approximately 30-40 seconds, it will alternate between hard and soft with each press, accompanied by clicking noises from the valves. Another 30-40 seconds later, the pedal will become consistently soft again. At this point, stop pumping the pedal; the valves will continue clicking.

      Note
      This step can consume up to 1 liter of brake fluid; recommended assistance.
    6. Close the outer bleed valve when the routine is succeeded.
    7. Make sure that the reservoir does not go empty, or that the catch bottle does not overfill.
    8. Repeat step 13.b through step 13.g until clean fluid without bubbles flows out of the caliper.
    9. Remove the fluid catcher, and then torque the LH front caliper outer bleed valve and install the outer valve cap.
