Functional Test

  1. Operating Check: 
    1. Depress the brake pedal several times with the engine off and check that there is no change in the pedal reserve height. For pedal reserve height, see BRAKE PEDAL RESERVE HEIGHT  under ADJUSTMENTS.
    2. Depress the brake pedal and start the engine. If the pedal goes down slightly, operation is normal.
