  2. INSPECT AND ADJUST BRAKE PEDAL STROKE SENSOR ASSEMBLY 
    1. Inspect the brake pedal stroke sensor assembly.
      1. Connect the Techstream to the DLC3 with the power switch off.
      2. Turn the power switch on (IG).
      3. Turn the Techstream on and enter the following menus: Chassis / ABS/VSC/TRAC / Data List / Stroke Sensor.

        Chassis > ABS/VSC/TRAC > Data List 

        Tester Display
        Stroke Sensor
      4. Read the stroke sensor value without the brake pedal depressed.

        Standard Voltage (without the brake pedal depressed)

        0.8 to 1.2 V

        HINT: 

        If the stroke sensor value is not within the standard voltage, adjust the brake pedal stroke sensor assembly.

    2. Adjust the brake pedal stroke sensor assembly.
      1. Remove the No. 1 instrument panel under cover sub-assembly.

        Refer to PROCEDURE - Step 8
