Abs With EBD & BA & TRAC & VSC System: Calibration

WARNING: This page is about a different car, the 2006 Toyota Tundra and 2005 Toyota Tundra. However, it is still accessible from the selected car via links, so may be relevant.

DESCRIPTION
After replacing the VSC relevant components or performing "Front wheel alignment adjustment", clearing and reading the sensor calibration data is necessary.

Follow the chart to perform calibration.

USING SST CHECK WIRE:
CLEAR ZERO POINT CALIBRATION
HINT:

After replacing the yaw rate & deceleration sensor, make sure to clear zero point calibration data in the skid control ECU and perform zero point calibration.
1. Turn the ignition switch to the ON position.
2. Using SST, connect and disconnect terminals TS and CG of the DLC3 4 times or more within 8 seconds.

3. Check that the warning light indicates the normal system code.
4. Remove the SST from the terminals of the DLC3.
5. Perform zero point calibration of the yaw rate & deceleration sensor using a check wire (refer to step 3).

PERFORM ZERO POINT CALIBRATION OF YAW RATE AND DECELERATION SENSOR
After replacing the master cylinder solenoid (skid control ECU) and/or yaw rate & deceleration sensor, make sure to perform yaw rate 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 in a stationary condition (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. Using SST, connect terminals TS and CG of the DLC3.

  3. Check that the steering wheel is in the straight-ahead position.
  4. AT: Check that the shift lever is in the P position and apply the parking brake.
    MT: 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.
  5. Turn the ignition switch to the ON position.
  6. Keep the vehicle in a stationary condition on a level surface for 2 seconds or more.
  7. Check that the VSC TRAC warning light blinks.
NOTE: The VSC TRAC warning light (and VSC OFF indicator light (4WD)) stay on when obtaining the zero point.

HINT:
- If the VSC TRAC warning light does not blink, perform the zero point calibration again.
- 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.
USING HAND-HELD TESTER:
CLEAR ZERO POINT CALIBRATION
After replacing the yaw rate & deceleration sensor, make sure to clear zero point calibration data in the skid control ECU and perform zero point calibration.
1. Connect the hand-held tester to the DLC3.
2. Turn the ignition switch to the ON position.
3. Operate the hand-held tester to erase the codes.

4. Perform zero point calibration of the yaw rate & deceleration sensor using the hand-held tester (refer to step 5).
PERFORM ZERO POINT CALIBRATION OF YAW RATE AND DECELERATION SENSOR
After replacing the master cylinder solenoid (skid control ECU) and/or yaw rate & deceleration sensor, make sure to perform yaw rate 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 in a stationary condition. (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. Check that the steering wheel is in the straight-ahead position and move the shift lever to the P position (A/T) or apply the parking brake (M/T).
    NOTE: DTC C1210/36 and C1336/39 will be recorded if the shift lever is not in the P position.
  2. Connect the hand-held tester to the DLC3.
  3. Turn the ignition switch to the ON position.
  4. Change the ECU to test mode with the hand-held tester. Enter the following menus: DIAGNOSTIC / OBD/MOBD / select vehicle / ABS/VSC / TEST MODE.

  5. Keep the vehicle in a stationary condition on a level surface for 2 seconds or more.
  6. 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)) stay on when obtaining the zero point.

HINT:
- If the VSC TRAC warning light does not blink, perform the zero point calibration again.
- 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.
