ICU (Integrated Control Unit): Removal

Remove the remote ground cable from the ground stud on the left strut tower.
Correctly isolate remote ground cable when servicing vehicle by installing the ground cable insulator on the strut tower ground stud. This will prevent accidental grounding of the remote ground cable.

Using a brake pedal positioning tool, depress brake pedal past its first one inch of travel and hold in this position. This will isolate the master cylinder reservoir from the brake hydraulic system, not allowing the brake fluid to drain out of the reservoir. See Fig 1.
