Bleeding Brake System

CAUTION: The anti-lock brake system must be bled using the following procedure. If this procedure is not followed, air will be trapped in the Hydraulic Control Unit (HCU), resulting in a spongy pedal.
  1. Unplug ECU 55-pin connector. ECU is located in engine compartment, under upper radiator support. Install Breakout Box (014-00322) and ABS Adapter (T90P-50-ALA). Set BLEEDER/HARNESS switch to BLEED position. Set ignition switch to ON position. Red OFF indicator light will glow.
  2. Press MOTOR button on adapter. Pump motor will run. Red indicator light will go out, and Green ON indicator will glow. Pump will run for 60 seconds. If pump motor is to be turned off before 60 seconds has elapsed, press ABORT button.
  3. After pump motor runs for 20 seconds, press and hold VALVE button for 20 seconds, then release. Pump will continue to run for an additional 20 seconds. The brakes may now be bled in the conventional manner using the following sequence: right rear, left front, left rear, and right front.
