Installation

1. Install the VSA modulator-control unit in the reverse order of removal, and note these items:
   - Tighten all mounting hardware to the specified torque values.
   - Align the connecting surface of the VSA control unit 47P connector.
   - Carefully push in the lock of the VSA control unit 47P connector until you hear it click into place, then confirm the connector is fully seated.
   - Reconnect the six brake lines, then tighten the flare nuts to specified torque values.
   - Bleed the brake system, starting with the front wheels.

1. Start the engine, and check that the ABS and VSA indicators go off.

1. Test-drive the vehicle, and check that the ABS and VSA indicators do not come on.

1. If the brake pedal is now spongy, there may be air trapped in the modulator and then induced into the normal brake system during modulation. Bleed the brake system again, starting with the front wheels.
