The ABS section of the brake system cannot be bled without the use of the scan tool; there are no manual procedures for bleeding the HCU. Using the scan tool, select ECU VIEW, then select ABS MISCELLANEOUS FUNCTIONS to access the bleeding procedures. Follow the instructions displayed on the scan tool.

Think of it as two systems:

Bleed the calipers/ cylinders first.
Left rear wheel
Right front wheel
Right rear wheel
Left front wheel

Then bleed the abs system.

With the ABS bleeding completed, bleed the base brake system a second time using the same procedures that were outlined for bleeding the base brake system the first time. Once again, check the fluid level in the master cylinder and be sure that it is at the FULL level.

Bump.
