DTC C1210 Zero Point Calibration of Yaw Rate Sensor Undone

DTC C1336 Zero Point Calibration of Acceleration Sensor Undone


DESCRIPTION

The skid control ECU (master cylinder solenoid) receives signals from the yaw rate sensor assembly via the CAN communication system.
The yaw rate sensor assembly has a built-in acceleration sensor and detects the vehicle's condition using 2 circuits (GL1, GL2). If there is trouble in the bus lines between the yaw rate sensor assembly and the CAN communication system, DTCs U0123 (yaw rate sensor communication trouble) and U0124 (acceleration sensor communication trouble) are stored.
The DTCs are also stored when the calibration has not been completed.

2.PERFORM ZERO POINT CALIBRATION OF YAW RATE AND ACCELERATION SENSOR

  1. Perform zero point calibration of the yaw rate and acceleration sensor (Click here).


NEXT


3.PERFORM TEST MODE (SIGNAL CHECK)

  1. Turn the ignition switch off.

  1. Perform the signal check in the Test Mode Procedure (Click here).

    OK:
    All test mode DTCs are cleared.


NG
Go to step 4
OK

END

4.CHECK YAW RATE SENSOR ASSEMBLY INSTALLATION

  1. Turn the ignition switch off.

  1. Check that the yaw rate sensor assembly has been installed properly (Click here).

    OK:
    The sensor is tightened to the specified torque.
    The sensor is not installed at an angle.


NG
INSTALL YAW RATE SENSOR ASSEMBLY CORRECTLY (Click here)
OK


5.READ VALUE USING GTS (YAW RATE AND ACCELERATION SENSOR)

  1. Turn the ignition switch off.

  1. Connect the GTS to the DLC3.

  1. Turn the ignition switch to ON.

  1. Turn the GTS on.

  1. Enter the following menus: Chassis / ABS/VSC/TRC / Data List.
