Bleeding the ABS System

Print


NOTE
Bleeding the hydraulic control unit (HCU) is required only when removing or installing the HCU or master cylinder, or opening the lines to the HCU.


NOTE
Carrying out the System Bleed function drives trapped air from the HCU. Subsequent bleeding removes the air from the brake hydraulic system through the bleeder screws.


NOTE
Adequate voltage to the HCU module is required during the anti-lock control portion of the system bleed.

  1. Connect the WDS or equivalent Tester.
