(a) Check the zero point voltage of the yaw rate sensor.

(1) Keep the vehicle in a stationary condition on a level surface for 1 second or more.

(b) Check the output of the yaw rate sensor.

(1) Move the shift lever to the D position, drive the vehicle at a speed of approximately 3 mph (5 km/h), and turn the steering wheel either to the left or right 90° or more until the vehicle makes 180° turn.

(2) Stop the vehicle and move the shift lever to the position. Check that the skid control buzzer sounds for 3 seconds.

HINT:

  • If the skid control buzzer sounds, the signal check is completed normally.
  • If the skid control buzzer does not sound, check the skid control buzzer circuit, then perform the signal check again.
  • If the skid control buzzer does not sound yet, there is a malfunction in the yaw rate sensor, so check the DTC.
  • Make a 180° turn. At the end of the turn, the direction of the vehicle should be within 180 +- 5° of its start position.
  • Do not spin the wheels.
