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

PERFORM ZERO POINT CALIBRATION OF YAW RATE SENSOR AND DECELERATION SENSOR (USING SST CHECK WIRE)
HINT:

After replacing the yaw rate sensor and/or the brake actuator assembly, make sure to perform the yaw rate sensor and deceleration sensor zero point calibration.
NOTE:
- While performing the calibration, do not tilt, move or shake the vehicle. Keep it in a stationary condition. Do not start the engine.
- Be sure to perform the calibration on a level surface that has an inclination of less than 1 degree.
1. Move the shift lever P.
2. Clear the zero point calibration using the SST check wire.

  1. Turn the ignition switch ON.

  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 lamp indicates the normal code.
  4. Remove the SST from the terminals of the DLC3.
3. Procedures for test mode:
  1. Turn the ignition switch OFF.
  2. Apply the parking brake (the parking brake switch is turned ON).
  3. Using SST, connect terminal TS and CG of the DLC3.

  4. Check that the steering wheel is in the center position and move the shift lever P.
  5. Turn the ignition switch ON.
4. Keep the vehicle in the stationary condition on the level surface for 2 seconds or more.
5. Check that the VSC warning lamp blinks.
  HINT:
  
  If the VSC warning lamp does not blink, perform the zero point calibration again.
PERFORM ZERO POINT CALIBRATION OF YAW RATE SENSOR AND DECELERATION SENSOR (USING HAND-HELD TESTER)
NOTE:
- While performing the calibration, do not tilt, move or shake the vehicle. Keep it in a stationary condition. Do not start the engine.
- Be sure to perform the calibration on a level surface (within an inclination of 1 degree).
1. Check that the steering wheel is in the center position and move the shift lever to the P position.
2. Connect the hand-held tester to the DLC3.
3. Turn the ignition switch ON.
4. Operate the hand-held tester to test mode (SIGNAL CHECK).
5. Obtain zero point of the yaw rate sensor and deceleration sensor:
  1. Keep the vehicle in the stationary condition on the level surface for 2 seconds or more.
  2. Check that the VSC warning lamp blinks.
  HINT:
  
  If the VSC warning lamp does not blink, perform the zero point calibration again.
6. Turn the ignition switch OFF.
