  2. To check circuit warning sensor, turn ignition on, release parking brake, and ensure light is off. Open bleeder screw on one wheel and depress brake pedal. Light should glow.
  3. Close bleeder screw, replenish brake fluid and bleed hydraulic system. Check that light goes out after testing. If not, differential pressure pin in master cylinder must be reset.
