NOTE: This procedure is only required when a new hydraulic control unit (HCU) is installed.
NOTE: When any part of the hydraulic system is disconnected for repair or installation of new components, air can get into the system and cause
spongy brake pedal action. This requires bleeding of the hydraulic system after it is correctly connected. The hydraulic system can be bled manually or
with pressure bleeding equipment.
1. 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.
Connect the scan tool to the vehicle.
2. Access the ABS HCU bleed function and follow the directions on the scan tool.
3. Manually bleed the brake hydraulic system.
4. Repeat the procedure carrying out a total of 2 scan tool cycles and 2 manual bleed cycles.
