Removal & 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.
- Push the tab (A), and pull up the lock (B) of the VSA modulator-control unit 47P connector (C), and the connector disconnects itself.
- Disconnect the six brake lines from the VSA modulator-control unit (D).
- Remove the three 6 mm nuts, then remove the VSA modulator-control unit with bracket (E) from the body.
Remove the three 6 mm bolts, then separate the VSA modulator-control unit from the bracket.
- Install the VSA modulator-control unit on the bracket with three 6 mm bolts.
- Install the VSA modulator-control unit/bracket, then tighten the three 6 mm nuts.
- Reconnect the six brake lines, then tighten the flare nuts.
- Align the connecting surface of the VSA modulator-control unit 47P connector.
- Push in the lock of the VSA modulator-control unit 47P connector until you hear it click into place, then confirm the connector is fully seated.
- Bleed the brake system, starting with the front wheels.
Do VSA sensor neutral position memorization, as follows:
With the ignition switch OFF, connect the HDS to the 16P date link connector (DLC) (A) under the left side of the driver's dashboard.
- Short the SCS circuit to body ground using the HDS.
- Make sure the vehicle is parked on a level surface.
- Do not touch the brake pedal during step e through j.
- Turn the ignition switch ON (II).
- The ABS indicator comes on for 2 seconds and goes off.
- After the ABS indicator goes off, push the VSA OFF switch once within 2 seconds.
- After the ABS indicator comes on, push the VSA OFF switch once within 2 seconds.
- The VSA activation indicator blinks and the system starts VSA sensors neutral position memorization.
- When the ABS indicator, VSA indicator, and VSA activation indicator go off, the memorizing is done. If the indicators do not go off, retry these steps.
- With the ignition switch OFF, connect the HDS to the 16P date link connector (DLC) (A) under the left side of the driver's dashboard.
- Start the engine, and check that the ABS and VSA indicator goes off.
- Test-drive the vehicle, and check that the ABS and VSA indicator does not come on.
- 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.
