VEHICLE STABILITY CONTROL SYSTEM, Diagnostic DTC:C1210 and 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 and acceleration sensor (airbag sensor assembly) via the CAN communication system.

The airbag sensor assembly has a built-in yaw rate and 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 (airbag sensor assembly) and the CAN communication system, the DTC U0124 (Lost Communication with Lateral Acceleration Sensor Module) is output.

The DTCs are also output when the calibration has not been completed.

DTC No.

  3. CHECK AIRBAG SENSOR ASSEMBLY INSTALLATION

    1. Turn the ignition switch off.

    2. Check that the airbag sensor assembly has been installed properly.

      Click here

      OK

      The sensor should be tightened to the specified torque.

      The sensor is not installed in a tilted position.

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

    1. Connect the GTS to the DLC3.

    2. Turn the ignition switch to ON.

    3. Turn the GTS on.

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

    5. According to the display on the GTS, read the Data List.

    6. Check the yaw rate and acceleration sensor (airbag sensor assembly) output value displayed on the GTS.

      OK

      The yaw rate and acceleration sensor (airbag sensor assembly) output value is normal.
