VEHICLE STABILITY CONTROL SYSTEM(for TMMF Made), Diagnostic DTC:C1336

DTC Code DTC Name
C1336 Zero Point Calibration of Acceleration Sensor Undone

DESCRIPTION

A new skid control ECU is supplied without zero point calibration for the yaw rate sensor and master cylinder pressure sensor. Until the zero points are calibrated, DTC C1336 remains stored. By entering test mode, the zero point calibration is automatically performed, and DTC C1336 is erased automatically.

DTC No. Detection Condition Trouble Area
C1336

When either of following conditions (1 or 2) detected:


  1. Vehicle driven without completion of zero point calibration.

  2. After zero point has been obtained, zero point voltage of sensor not between 2.38 V and 2.62 V.

  • Skid control ECU (Brake actuator assembly)

  • Zero point calibration incomplete

CAUTION / NOTICE / HINT

Note

When replacing the brake actuator assembly, perform the zero point calibration Click here.

Tech Tips

When U0123 or U0126 is output together with C1336, inspect and repair trouble areas indicated by U0123 or U0126 first.

PROCEDURE


  1. CHECK YAW RATE SENSOR (AIRBAG SENSOR ASSEMBLY)


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

      OK
      The sensor is tightened to the specified torque.
      The sensor is not tilted.

    NG

    INSTALL YAW RATE SENSOR (AIRBAG SENSOR ASSEMBLY) CORRECTLY

    OK

  2. PERFORM DECELERATION SENSOR ZERO POINT CALIBRATION


    1. Perform zero point calibration of the deceleration sensor Click here.

  3. RECONFIRM DTC


    1. Clear the DTC Click here.

    2. Start the engine.

    3. Drive the vehicle and turn the steering wheel to the right and left at a speed of 45 km/h (28 mph) or more.

    4. Check if the same DTC is recorded Click here.

      Result
      Result Proceed to
      DTC C1336 is not output A
      DTC C1336 is output (for LHD) B
      DTC C1336 is output (for RHD) C

      Tech Tips


      • The DTC is set if the zero point calibration has not been completed successfully.

      • End the procedure when the same DTC is not set after completion of the zero point calibration.
