ELECTRONICALLY CONTROLLED BRAKE SYSTEM, Diagnostic DTC:C1210, C1336

DTC Code DTC Name
C1210 Zero Point Calibration of Yaw Rate Sensor undone
C1336 Zero Point Calibration of Deceleration Sensor undone

DESCRIPTION

The skid control ECU assembly receives signals from the yaw rate and acceleration sensor via CAN communication.

The yaw rate and acceleration sensor detects the vehicle condition using 2 circuits (GL1, GL2).

Tech Tips

If there are malfunctions in the bus lines between the yaw rate and acceleration sensor and the CAN communication system, DTCs U0123 (Lost Communication With Yaw Rate Sensor Module) and U0124 (Lost Communication With Lateral Acceleration Sensor Module) will be stored.

These DTCs (C1210 and C1336) will also be stored when zero point calibration has not been completed.

DTC No. Detection Item INF Code DTC Detection Condition Trouble Area Note
C1210 Zero Point Calibration of Yaw Rate Sensor undone 336 Yaw rate sensor zero point calibration is incomplete.

  • Zero point calibration undone

  • Yaw rate sensor (Yaw rate and acceleration sensor)

  • Skid control ECU assembly

(Perform zero point calibration and check for DTCs. If no DTCs are output again, the sensor is normal.)

 VSC DTC
C1336 Zero Point Calibration of Deceleration Sensor undone 318

Any of the following is detected:


  1. Acceleration sensor zero point calibration is incomplete.

  2. The vehicle is driven normally without zero point calibration completed.

  3. After completing zero point calibration, zero point voltage of the sensor is not within the range of 2.38 to 2.62 V.

  • Zero point calibration undone

  • Acceleration sensor (Yaw rate and acceleration sensor)

  • Skid control ECU assembly

(Perform zero point calibration and check for DTCs. If no DTCs are output again, the sensor is normal.)

 ABS DTC

CAUTION / NOTICE / HINT

Note

When replacing the skid control ECU assembly or yaw rate and acceleration sensor, perform initialization and calibration of the linear solenoid valve.

Tech Tips

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

      Chassis > ABS/VSC/TRC > Clear DTCs

    3. Turn the power switch off.

    4. Turn the power switch on (IG).

    5. Check if the same DTC is output.

      DTCs C1210 and/or C1336 are output. A
      DTCs C1210 and C1336 are not output. B

      Tech Tips


      • These DTCs are stored because zero point calibration has not been completed.

      • End the procedure if the same DTCs are not stored after completion of zero point calibration.

  3. CHECK YAW RATE AND ACCELERATION SENSOR INSTALLATION


    1. Turn the power switch off.

    2. Check that the yaw rate and acceleration sensor has been installed properly.

      Click here

      OK
      The yaw rate and acceleration sensor is tightened to the specified torque.
      The yaw rate and acceleration sensor is not tilted.
