      Standard pedal height from No. 2 Dash Panel Insulator Pad

      144.2 to 154.2 mm (5.68 to 6.07 in.)

    2. Adjust the pedal height.
      1. Disconnect the connector from the stop light switch.
      2. Loosen the stop light switch lock nut and turn the switch so that the pedal has free play.
      3. Loosen the push rod clevis lock nut.
      4. Adjust the pedal height by turning the push rod.

        Standard pedal height from No. 2 Dash Panel Insulator Pad

        144.2 to 154.2 mm (5.68 to 6.07 in.)

      5. Tighten the push rod clevis lock nut.

        Torque

        26 Nm (265 kgf cm, 19 ft.lbf)

    3. Turn the power switch ON (IG). While reading the stroke sensor 1 value shown on the Techstream, turn the stroke sensor slowly to the right and left to adjust it to the standard voltage.

      Standard voltage

      0.8 to 1.2 V

    4. Tighten the 2 bolts.

      Torque

      8.5 Nm (87 kgf cm, 75ft. lbf)

      NOTE:

      Do not depress the brake pedal while performing the linear valve offset learning, as this may cause a DTC to be stored.

    5. Perform the linear valve offset learning.
  3. CHECK BRAKE PEDAL FREE PLAY
    1. Press the pedal until a slight resistance is felt.

      Measure the distance as shown in the illustration.

      Standard pedal free play

      1.0 to 2.0 mm (0.0394 to 0.0787 in.)

      If the pedal free play is less than 1.0 mm (0.0394 in.), check the protrusion of the stop light switch shaft.

      Protrusion of the stop light switch shaft

      1.5 to 2.6 mm (0.0591 to 0.102 in.)

      If the protrusion is not within the specified value range, adjust it.

      If the protrusion is within the specified value range, troubleshoot the brake system and proceed to the "CHECK BRAKE PEDAL RESERVE DISTANCE" procedure below.

  4. CHECK BRAKE PEDAL RESERVE DISTANCE
    1. Release the parking brake. Start the engine.
    2. Depress the brake pedal and check the pedal reserve distance.

      1. Depress the pedal with a force of 200 N (20 kgf, 45.0 lbf).
      2. Measure the distance between the pedal and No. 2 dash panel insulator pad shown in the illustration.

        Standard pedal reserve distance

        More than 95 mm (3.74 in.)

        If the distance is not as specified, troubleshoot the brake system.
