With Hand-Held Tester

  1. Hook up the hand-held tester to the DLC3. See Figure.
  2. Start the engine and check that the VSC warning light blinks.
  3. Check the yaw rate sensor by shifting the shift lever to D and drive the vehicle at approximately 3 mph (5 km/h). Turn the steering wheel either left or right 90° or more, and maintain 180° circular drive. Do not spin the wheels. At the end of the turn, the direction of the vehicle should be within 175°-185° of start position.
  4. Stop the vehicle, shift to P and check that the VSC buzzer sounds for 3 seconds. If the VSC buzzer sounds, the sensor check is completed normally. If the VSC buzzer does not sound, check the VSC buzzer circuit. See SYSTEM TESTING . Perform the sensor check again.
  5. If the VSC buzzer still won't sound there is a malfunction in the VSC sensor. Check the DTC. See Fig 1.
  6. Check the steering angle sensor from the stationary condition by turning the steering wheel to either left or right to the full lock position. Then turn back to the neutral position.
  7. Turn the steering wheel to the neutral position and turn the ignition switch OFF. Check that the shift lever position is at P.
  8. If the VSC buzzer still won't sound, read the DTC by following the tester screen. Please refer to hand-held tester operator's manual for further details.
