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

DTC    C1336/39    Zero Point Calibration of Deceleration Sensor Undone

for Preparation Click here


DESCRIPTION

The ABS and TRACTION actuator assembly receives signals from the yaw rate and acceleration sensor via the CAN communication system.
The yaw rate sensor has the 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 and acceleration sensor and the CAN communication system, the DTCs U0123/62 (yaw rate sensor communication trouble) and U0124/95 (acceleration sensor communication trouble) are output.
The DTCs are also output when the calibration has not been completed.

DTC No.
DTC Detecting Condition
Trouble Area
C1210/36
Zero point calibration of yaw rate sensor undone.
  1. ABS and TRACTION actuator assembly (Skid control ECU)
  2. Zero point calibration undone
    (Perform zero point calibration and check DTC.
    If DTC is not output again, the sensor is normal)
C1336/39
When either of the following is detected:
  1. The vehicle runs in the normal mode with zero point calibration undone.
  2. After the zero point has been obtained, the zero point voltage of the sensor is not between 2.38 and 2.62 V.
  1. ABS and TRACTION actuator assembly (Skid control ECU)
  2. Zero point calibration undone
    (Perform zero point calibration and check DTC.
    If DTC is not output again, the sensor is normal)

INSPECTION PROCEDURE

NOTICE:
When replacing the ABS and TRACTION actuator assembly, perform zero point calibration (Click here).

HINT:
When U0123/62, U0124/95 or U0126/63 is output along with C1210/36 or C1336/39, inspect and repair trouble areas indicated by U0123/62, U0124/95 or U0126/63 first.

1.CHECK YAW RATE AND ACCELERATION SENSOR INSTALLATION

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

    OK:
    The sensor should be tightened to the specified torque.
    The sensor should not be tilted.



NG
INSTALL YAW RATE AND ACCELERATION SENSOR CORRECTLY
OK


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).

3.RECONFIRM DTC

  1. Clear the DTCs (Click here).

  1. Start the engine.

  1. Drive the vehicle and turn the steering wheel to the right and left at a speed of 24 mph (35 km/h) or more.

  1. Check that the same DTCs are recorded (Click here).

    HINT:
    Reinstall the sensors, connectors, etc. and restore the vehicle to its prior condition before rechecking for DTCs.


    Result:

    Condition
    		Proceed To
    DTCs (C1210/36 and C1336/39) are not output
    		A
    DTCs (C1210/36 and C1336/39) are output
    		B

    HINT:
    1. The DTCs are recorded because zero point calibration has not been completed.
    2. End the procedure since the same DTCs are not recorded after completion of zero point calibration.
    3. If troubleshooting has been carried out according to the problem symptoms table, refer back to the table and proceed to the next step (Click here).
