VSA Modulator-control Unit Removal and Installation

NOTE:
  • 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.
  • Plug the end of a hose and joints to prevent spilling brake fluid.
Removal

    NOTE: Brake lines are connected to the master cylinder (D) and to the left-front (E), the right-front (F), the left-rear (G), and the right-rear (H) brake systems.
  1. Remove the VSA modulator-control unit (I) with the bracket (J) from the body.

  1. Test-drive the vehicle, and make sure that the ABS and the VSA indicators do not come on.
    NOTE: If the brake pedal is spongy, there may be air trapped in the modulator which could then be induced into the normal brake system during modulation. Bleed the brake system again.
