VSA Modulator-Control Unit Removal and Installation

• 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.
  

Removal

1.	Pull up the lock (A) of the VSA control unit 46P connector (B), and the connector disconnects itself.

4.	Remove the two 6 mm nuts, then remove the VSA modulator-control unit from the bracket.

Installation

4.	Align the connecting surface of the VSA control unit 46P connector to the VSA modulator-control unit.

5.	Lower the lock of the VSA control unit 46P connector until you hear it click into place, then confirm the connector is fully seated.

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

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