VEHICLE STABILITY CONTROL SYSTEM, Diagnostic DTC:C1210, C1336

DTC Code DTC Name
C1210 Zero Point Calibration of Yaw Rate Sensor Undone
C1336 Zero Point Calibration of Acceleration Sensor Undone

DESCRIPTION

The skid control ECU (brake actuator assembly) receives signals from the yaw rate sensor assembly via the CAN communication system.

The yaw rate sensor assembly has a built-in acceleration sensor.

If there is trouble in the bus lines between the yaw rate sensor assembly and the CAN communication system, DTCs U0123 (Lost Communication with Yaw Rate Sensor Module) and U0124 (Lost Communication with Lateral Acceleration Sensor Module) are stored.

DTC C1210 and C1336 are also stored when calibration has not been completed.

DTC Code DTC Detection Condition Trouble Area
C1210 Zero point calibration of the yaw rate sensor is incomplete.

  • Yaw rate sensor assembly

  • Skid control ECU (Brake actuator assembly)
C1336 Zero point calibration of the acceleration sensor is incomplete.

  • Acceleration sensor (Yaw rate sensor assembly)

  • Skid control ECU (Brake actuator assembly)

INSPECTION PROCEDURE

Note

After replacing the brake actuator assembly and/or yaw rate sensor assembly, perform calibration Click here.

Tech Tips

When DTC U0123 and/or U0124 is output along with DTC C1210 and/or C1336, inspect and repair trouble areas indicated by DTC U0123 and/or U0124 first Click here.

    OK

    END

  3. CHECK YAW RATE SENSOR ASSEMBLY INSTALLATION


    1. Turn the ignition switch off.

    2. Check that the yaw rate sensor assembly is 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

  4. READ VALUE USING INTELLIGENT TESTER (DECELERATION SENSOR / YAW RATE SENSOR)


    1. Turn the ignition switch off.

    2. Connect the intelligent tester to the DLC3.

    3. Turn the ignition switch to ON.

    4. Turn the intelligent tester on.

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