Function Check

WARNING: This page is about a different car, the 2011 Infiniti QX56. However, it is still accessible from the selected car via links, so may be relevant.
  1. Turn the ignition switch OFF.
  2. Depress the brake pedal 20 times or more.
    NOTE: The pressure loss in the accumulator results in a large brake pedal stroke. In addition to this, the brake pedal depression becomes lighter in initial stage.
  3. Turn the ignition switch ON with the brake pedal depressed to check that the clearance between the brake pedal and the dash lower panel decreases.
