BRAKE CONTROL: VEHICLE STABILITY CONTROL SYSTEM: C1210/36: Zero Point Calibration of Yaw Rate Sensor Undone

DTC C1210/36 - Zero Point Calibration of Yaw Rate Sensor Undone

DTC C1336/39 - Zero Point Calibration of Acceleration Sensor Undone

DESCRIPTION

Brake actuator receives signals from the yaw rate sensor via the CAN communication system.
The yaw rate sensor has a built-in acceleration sensor.
If there is trouble in the bus lines between the yaw rate and acceleration sensor and CAN communication system, DTC U0123/62 (yaw rate sensor communication trouble) and U0124/95 (acceleration sensor communication trouble) are output.
The DTC is also output when the calibration has not been completed.

INSPECTION PROCEDURE

PROCEDURE

1. CHECK YAW RATE AND ACCELERATION SENSOR INSTALLATION
(a) Check that the yaw rate and acceleration sensor has been installed properly .
OK:
The sensor should be tightened to the specified torque.
The sensor should not be tilted.
NOTE: When replacing the yaw rate and acceleration sensor, perform zero point calibration. Calibration

NG -- INSTALL YAW RATE AND ACCELERATION SENSOR
OK -- Continue to next step.
2. PERFORM YAW RATE SENSOR ZERO POINT CALIBRATION
(a) Perform zero point calibration of the yaw rate and acceleration sensor .
NEXT -- Continue to next step.
3. RECONFIRM DTC
(a) Clear the DTCs .
(b) Turn the ignition switch to the ON position.
(c) Check if the same DTCs are recorded .
Result:






B -- END
A -- REPLACE YAW RATE AND ACCELERATION SENSOR
