VSA Modulator-Control Unit Removal and InstallationNOTE:
^ Do not spill brake fluid on the vehicle; it may damage the paint; if brake fluid gets on the paint, wash it off immediately with water.
^ Be careful not to damage or deform the brake lines during removal and installation.
^ To prevent the brake fluid from flowing, plug and cover the hose ends and joints with a shop towel or equivalent material.
