Safety Warning

DIY auto repair can cause serious injury, fire, or vehicle damage. These guides are for informational purposes only. Always follow OEM torque specs, wear PPE, and consult a certified mechanic if you are unsure. You are solely responsible for your safety.

Vehicle Stability Control System: Calibration

2008 Scion xD AutomaticSECTION Calibration

DESCRIPTION

After replacing the VSC relevant components or performing "Front wheel alignment adjustment", clear and read the sensor calibration data.

Follow the chart to perform calibration.

OPERATION CHART

Replacing Part / Operation	Necessary Operation
Skid control ECU	Yaw rate and acceleration sensor zero point calibration
Yaw rate and acceleration sensor	Clearing zero point calibration data Yaw rate and acceleration sensor zero point calibration
Front wheel alignment adjustment	Clearing zero point calibration data Yaw rate and acceleration sensor zero point calibration

OBTAIN ZERO POINT OF YAW RATE AND ACCELERATION SENSOR (Using Techstream)
NOTE:
- While obtaining the zero point, keep the vehicle stationary and do not vibrate, tilt, move, or shake it. (Do not start the engine.)
- Be sure to perform this procedure on a level surface (with an inclination of less than 1 degree).
1. Clear the zero point calibration data.
  1. Turn the ignition switch to OFF.
  2. Check that the steering wheel is in the straight-ahead position.
  3. Check that the shift lever is in the P position (for automatic transaxle model) or the parking brake is applied (for manual transaxle model).
  4. Connect the Techstream to the DLC3.
  5. Turn the ignition switch to ON.
  6. Turn the Techstream on.
  7. Enter the following menu items: Chassis / ABS/ VSC/TRAC / Reset Memory.
  8. Turn the ignition switch to OFF.
    NOTE: If the ignition switch is turned to ON for more than 15 seconds with the shift lever in the P position (for automatic transaxle model) or the parking brake applied (for manual transaxle model) after zero point of the yaw rate and acceleration sensor has been cleared, only the zero point of the yaw rate sensor will be stored. If the vehicle is driven under these conditions, the skid control ECU will store the zero point calibration for the acceleration sensor as not being completed. The skid control ECU will then also indicate this as a malfunction of the VSC system using the warning lights.
2. Perform zero point calibration of the yaw rate and acceleration sensor.
  1. Turn the ignition switch to OFF.
  2. Check that the steering wheel is in the straight-ahead position.
  3. Check that the shift lever is in the P position (for automatic transaxle model) or the parking brake is applied (for manual transaxle model).
    NOTE: DTCs C1210/36 and C1336/39 will be recorded if the shift lever is not in the P position (for automatic transaxle model) or the parking brake is not applied (for manual transaxle model) (See DTC C1210/36 ZERO POINT CALIBRATION OF YAW RATE SENSOR UNDONE; DTC C1336/39 ZERO POINT CALIBRATION OF ACCELERATION SENSOR UNDONE ).
  4. Connect the Techstream to the DLC3.
  5. Turn the ignition switch to ON.
  6. Turn the Techstream on.
  7. Enter the following menu items: Chassis / ABS/ VSC/TRAC / Test Mode.
  8. After the Test Mode has been entered, keep the vehicle stationary on a level surface for 2 seconds or more.
  9. Check that the VSC OFF indicator light comes on for several seconds and then blinks in Test Mode.
    HINT:
    - The SLIP indicator light remains on during Test Mode because traction control is prohibited (The SLIP indicator light goes off when the VSC OFF switch is ON.)
    - If the VSC OFF indicator light does not blink, perform zero point calibration again.
    - The zero point calibration is performed only once after the system enters the Test Mode.
    - Calibration cannot be performed again until the stored data is cleared.

  10. Turn the ignition switch to OFF and disconnect the Techstream.
OBTAIN ZERO POINT OF YAW RATE AND ACCELERATION SENSOR (for Using SST Check Wire)
NOTE:
- While obtaining the zero point, keep the vehicle stationary and do not vibrate, tilt, move, or shake it. (Do not start the engine.)
- Be sure to perform this procedure on a level surface (with an inclination of less than 1 degree).
1. Clear the zero point calibration data.
  1. Turn the ignition switch to OFF.
  2. Check that the steering wheel is in the straight-ahead position.
  3. Check that the shift lever is in the P position (for automatic transaxle model) or apply the parking brake (for manual transaxle model).
  4. Turn the ignition switch to ON.
  5. The warning light and indicator light come on for 3 seconds to indicate that the initial check is completed.

  6. Using SST, connect and disconnect terminals TS and CG of the DLC3 4 times or more within 8 seconds.

  7. Check that the VSC OFF indicator light comes on.
    NOTE: If the ignition switch is turned to ON for more than 15 seconds with the shift lever in the P position (for automatic transaxle model) or the parking brake applied (for manual transaxle model) after the zero point of the yaw rate and acceleration sensor has been cleared, only the zero point of the yaw rate sensor will be stored.

  4. Using SST, connect terminals TS and CG of the DLC3.

  5. Turn the ignition switch to ON.
  6. Keep the vehicle stationary on a level surface for 2 seconds or more.

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.
