Toyota Sienna Service Manual: Zero Point Calibration of Yaw Rate Sensor Undone
DESCRIPTION
The skid control ECU receives signals from the yaw rate sensor via CAN communication system.
Yaw rate sensor has the built-in deceleration sensor.
If there is trouble in the bus lines between the yaw rate and deceleration sensor and CAN communication system, the DTC U0123/62 (yaw rate sensor communication trouble) and U0124/95 (deceleration sensor communication trouble) are output.
The DTC is also output when the calibration has not been completed.

INSPECTION PROCEDURE
HINT: When U0073/94, U0100/65, U0123/62, U0124/95 or U0126/63 are output accompanied with C1210/36 or C1336/39, inspect and repair the trouble areas indicated by U0073/94, U0100/65, U0123/62, U0124/95 or U0126/63 first.
1 PERFORM ZERO POINT CALIBRATION OF YAW RATE AND DECELERATION SENSOR
(a) Perform the zero point calibration of the yaw rate and deceleration sensor (See page BC-70).
2 RECONFIRM DTC
(a) Clear the DTCs (See page BC-82).
(b) Turn the ignition switch to the ON position.
(c) Are the same DTCs recorded (See page BC-82).
Result
3 CHECK YAW RATE AND DECELERATION SENSOR INSTALLATION
(a) Check that the yaw rate and deceleration sensor has been installed properly (See page BC-197).
NOTICE: When replacing the yaw rate and deceleration sensor, perform zero point calibration (See page BC- 70).

Approach warning
When your vehicle is too close to a vehicle ahead, and sufficient automatic
deceleration via the cruise control is not possible, the display
will flash and the buzzer will sound to alert the driver. An example of
this would be if another driver cuts in front of you while you are following
a vehi ...
