Toyota Sienna Service Manual: Yaw rate sensor check (when using intelligent tester)
(a) 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 5 km/h (3 mph), and turn the steering wheel either to the left or right 90° or more until the vehicle makes a 180° turn.
(2) Stop the vehicle and move the shift lever to the P 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 VSC sensor, so check the DTC.
- Make 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.
