Vehicle Stability Control System: Calibration

2009 Toyota FJ Cruiser RWDSECTION Calibration
  1. DESCRIPTION 
    1. After replacing the VSC relevant components or performing "Front wheel alignment adjustment", clearing and reading the sensor calibration data are necessary.
    2. Follow the chart to perform calibration.
      CALIBRATION OPERATION CHART

      Replacing Parts Necessary Operations
      Skid Control ECU Yaw rate sensor and deceleration sensor zero point calibration.
      Yaw Rate Sensor
      1. Clearing zero point calibration data.
      2. Yaw rate sensor and deceleration sensor zero point calibration.
      Front Wheel Alignment
      1. Clearing zero point calibration data.
      2. Yaw rate sensor and deceleration sensor zero point calibration.
  2. CLEAR ZERO POINT CALIBRATION (for Using a Techstream) 

    HINT:

    After replacing the yaw rate and deceleration sensor or adjusting the front wheel alignment, be sure to clear the zero point calibration data in the skid control ECU and perform zero point calibration.

    1. Turn the ignition switch off.
    2. Check that the steering wheel is in the straight-ahead position.
    3. A/T: Check that the shift lever is in the P position and apply the parking brake.
    4. M/T: Check that the shift lever is in neutral and apply the parking brake.
    5. Connect the Techstream to the DLC3.
    6. Turn the ignition switch to ON.
    7. Select the following menu items: Chassis / ABS/ VSC/TRAC / Reset Memory
  3. PERFORM ZERO POINT CALIBRATION OF YAW RATE SENSOR AND DECELERATION SENSOR (for Using a Techstream) 

    HINT:

    After replacing the skid control ECU and/or yaw rate and deceleration sensor, or adjusting the front wheel alignment, be sure to perform yaw rate sensor and deceleration sensor zero point calibration.

    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.)
    • Be sure to do this on a level surface (with an inclination of less than 1 degree).
    1. Procedures for test mode.
      1. Turn the ignition switch off.
      2. Check that the steering wheel is in the straight-ahead position.
      3. A/T: Check that the shift lever is in the P position and apply the parking brake.

        M/T: Check that the shift lever is in neutral and apply the parking brake.

        NOTE: DTC C1210/36 and C1336/39 will be recorded if the shift lever is not in the P position.
      4. Connect the Techstream to the DLC3.
      5. Turn the ignition switch to ON.
      6. Switch the ECU to test mode using the Techstream.

        Select the following menu items: Chassis / ABS/ VSC/TRAC / Test Mode

      7. Keep the vehicle stationary on a level surface for 2 seconds or more.
      8. Check that the VSC TRAC warning light blinks as shown in the illustration.
        NOTE: The VSC TRAC warning light (and VSC OFF indicator light (4WD or 2WD with rear differential lock)) stay ON when obtaining the zero point.

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.
