INSPECT
A. Turn the ignition to the "RUN" position, turn engine off. Apply brake pedal with moderate force and hold. Note pedal travel and feel.
^ If pedal feels firm and constant and pedal travel is not excessive, start the engine. With the engine running, re-check the pedal travel. If it's
still firm and constant and pedal travel is not excessive, go to Step B.
^ If pedal feels soft or has excessive travel either initially or after engine start, the following procedure may be used. With the Scan Tool,
release then apply each motor 2 to 3 times and cycle each solenoid 5 to 10 times. When finished, be sure to apply the front and rear motors
to ensure the pistons are in the upmost position. DO NOT DRIVE THE VEHICLE. If a Scan Tool is not available, remove foot from brake
pedal, start the engine and allow it to run for at least 10 seconds to initialize the ABS. DO NOT DRIVE THE VEHICLE. After 10 seconds,
turn the ignition off. This initialization procedure MUST be repeated 5 times to ensure any trapped air has been dislodged. Now repeat
bleeding procedure starting at Step 1.
B. Road test the vehicle.
^ Make several normal (non-ABS) stops from a moderate speed to ensure proper brake system function. Allow adequate cooling time between
stops.
