3. Disconnect the six brake lines.
4. Remove the two 8 mm nuts.
5. Remove the VSA modulator-control unit.
Installation
1. Install the VSA modulator-control unit, then tighten the
two 8 mm nuts.
2. Align the connecting surfaces of the VSA control unit 42P
connector.
3. Push the locking lever of the VSA control unit 42P connec-
tor down until you hear a click.
4. Connect the pressure sensor 3P connector.
