Brake Pedal Stroke Sensor: Installation

NOTE: While the battery is connected, even if the engine switch is off, the brake control system activates when the brake pedal is depressed or the door courtesy switch turns on. Therefore during servicing of the brake system components, do not operate the brake pedal and open/close the doors while the battery is connected.
  1. INSTALL BRAKE PEDAL STROKE SENSOR ASSEMBLY 
    1. When installing a new brake pedal stroke sensor assembly:
      NOTE:
      • Do not break the sensor lever set pin before installing the brake pedal stroke sensor with the bolts.
      • If the sensor lever set pin breaks while tightening the bolt, do not use that sensor.
      1. Connect the sensor connector.
      2. Install a new sensor with the 2 bolts.

        Torque: 8.5 N*m (87 kgf*cm, 75 in.*lbf) 

        NOTE:
        • Engage the sensor lever with the brake pedal groove.
        • Check that there is no foreign matter attached to the contact surface of the sensor.
        • Check that the tip of the sensor lever is protruding from the brake pedal groove.
        • During installation, do not operate the brake pedal.

      3. Firmly depress the brake pedal and break the sensor lever set pin.
      4. Remove the broken lever set pin.
    2. When reusing the brake pedal stroke sensor assembly:
      1. Connect the sensor connector.
      2. Temporarily install the sensor with the 2 bolts.
        NOTE:
        • Engage the sensor lever with the brake pedal groove.
        • Check that there is no foreign matter attached to the contact surface of the sensor.
      3. Connect the cable to the negative battery terminal.
      4. Connect the Techstream to the DLC3.

      5. Turn the engine switch on (IG). Reading the value of the stroke sensor 1 shown on the data monitor, turn the sensor slowly to the right and left to adjust the output voltage to the standard voltage.

        Standard voltage: 0.8 to 1.2 V 

      6. Tighten the 2 bolts.

        Torque: 8.5 N*m (87 kgf*cm, 75 in.*lbf) 

        NOTE: Do not depress the brake pedal after turning the engine switch on (IG).
