STOP LIGHT SWITCH ADJUSTMENT

PROCEDURE


  1. CHECK THE DATA LIST FOR STOP LIGHT SWITCH ASSEMBLY


    1. Turn the ignition switch off.

    2. Connect the GTS to the DLC3.

    3. Turn the ignition switch to ON.

    4. Enter the following menus: Chassis / ABS/VSC/TRC / Data List / Stop Light SW and Master Cylinder Pressure Sensor 1 Click here.

    5. Without the brake pedal depressed, check that the Data List "Stop Light SW" is "OFF."

      Tech Tips

      If the Data List display is "ON", check and adjust the stop light switch assembly installation position.

    6. Depress the brake pedal slowly, and check that the Data List "Master Cylinder Pressure Sensor 1" is within the standard value when the Data List "Stop Light SW" is turned "ON".

      Standard pressure
      0.08 to 0.27 MPa(0.81 to 2.75 kgf/cm2, 11 to 39 psi)

      Tech Tips

      If the Data List display is outside the standard value, check and adjust the stop light switch assembly installation position.

    7. Check for DTCs.

      Tech Tips

      If DTC C1249 is output, check and adjust the stop light switch assembly installation position.

      (After Adjustment)

      Measure dimension B after installing the stop light switch assembly, and make adjustment so that it is larger than dimension A.

      Standard
      B - A = 1.0 to 2.0 mm (0.039 to 0.079 in.)

    2. After adjusting, check the value for the "Master Cylinder Pressure Sensor 1" on the Data List. If the value is outside the standard value, perform procedure (a) again.

      Standard pressure
      0.08 to 0.27 MPa (0.81 to 2.75 kgf/cm2, 11 to 39 psi)

      Tech Tips

      The installation position for the stop light switch assembly is adjustable by each thread pitch (approximately 1 mm) of the screw.
