Vehicle Stability Control System: Calibration

2009 Toyota Sequoia Limited, 5.7 Y, RWDSECTION Calibration
  1. DESCRIPTION 
    • After replacing components relating to the VSC or performing "Front Wheel Alignment Adjustment", clear and read the sensor calibration data.
    • Follow the chart to perform calibration.
    CALIBRATION CHART

    Replacing Part/Operation Necessary Operation
    VSC actuator (Skid Control ECU)
    1. Deceleration sensor zero point calibration.
    2. Master cylinder pressure sensor zero point calibration.
    Yaw Rate Sensor
    1. Zero point calibration data clearance.
    2. Deceleration sensor zero point calibration.
    Front Wheel Alignment Adjustment
    1. Zero point calibration data clearance.
    2. Deceleration sensor zero point calibration.
    3. Perform initialization of steering angle sensor.
  2. CLEAR ZERO POINT CALIBRATION DATA (WHEN USING TECHSTREAM) 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Operate the Techstream to clear the codes (select "Reset Memory").

      HINT:

      Refer to the Techstream operator's manual for further details.

  3. PERFORM ZERO POINT CALIBRATION OF MASTER CYLINDER PRESSURE SENSOR AND DECELERATION SENSOR (WHEN USING TECHSTREAM) 
    NOTE:
    • While obtaining the zero point, do not vibrate the vehicle by tilting, moving or shaking it and keep it stationary. Do not start the engine.
    • While obtaining the zero point, do not depress the brake and accelerator pedal.
    • Obtain the zero point on a level surface (with an inclination of less than 1°).
    1. Enter Test Mode.
      1. Turn the ignition switch off.
      2. Check that the shift lever is in P or N and apply the parking brake.
        CAUTION: Application of the parking brake is not necessary for entering test mode. However, apply the parking brake for safety.
      3. Connect the Techstream to the DLC3.
      4. Turn the ignition switch to ON.
        NOTE: Do not start the engine.
      5. Set the Techstream to test mode (select "Test Mode").

        HINT:

        Refer to the Techstream operator's manual for further details.

    2. Obtain the zero points of the master cylinder pressure sensor and deceleration sensor.
      1. Keep the vehicle stationary on a level surface for 1 second or more.

        HINT:

        • The zero point calibration is performed only once after the system enters test mode.
        • Calibration cannot be performed again until the stored data is cleared once.
      2. Check that the buzzer sounds for 1 second and DTC C1336 is cleared.
      3. Turn the ignition switch off.
  4. CLEAR ZERO POINT CALIBRATION DATA (WHEN USING SST CHECK WIRE) 
    1. Turn the ignition switch to ON.
    2. Using SST, connect and disconnect terminals 12 (TS) and 4 (CG) of the DLC3 4 times or more within 8 seconds.

      SST 09843-18040 

    3. Check that the VSC OFF indicator light comes on.
    4. Using a check wire, perform the zero point calibration of the deceleration sensor.

    • While obtaining the zero point, do not vibrate the vehicle by tilting, moving or shaking it and keep it stationary. Do not start the engine.
    • While obtaining the zero point, do not depress the brake pedal.
    • Obtain the zero point on a level surface (with an inclination of less than 1°).
    1. Enter Test Mode.
      1. Turn the ignition switch off.
      2. Check that the shift lever is in P or N and apply the parking brake.
        CAUTION: Application of the parking brake is not necessary for entering test mode. However, apply the parking brake for safety.
      3. Using SST, connect terminals 12 (TS) and 4 (CG) of the DLC3.

When to See a Mechanic

Stop DIY work and contact a certified mechanic immediately if any of the following apply:

  • • You smell fuel, burning insulation, or see smoke.
  • • Brakes feel soft, pull hard to one side, or make grinding noises.
  • • The engine overheats, stalls repeatedly, or misfires under load.
  • • You are missing required tools, torque specs, or safe lifting equipment.
  • • You are not confident in the next step or safety outcome.
