ABS 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 dripping, plug and cover the hose ends and joints with a shop towel.

  1. Disconnect the ABS modulator-control unit 25P connector (A) by pulling up the lock (B); the connector disconnects itself.
