  2. READ VALUE USING TECHSTREAM (G SENSOR) 
    1. Connect the Techstream to the DLC3.
    2. Turn the ignition switch to ON.
    3. Turn the Techstream on.
    4. Enter the following menus: Powertrain / Engine and ECT / Data List / Primary.
    5. In accordance with the display on the Techstream, read the Data List.

    REPLACE BRAKE ACTUATOR ASSEMBLY. Refer to  COMPONENTS [08/2013 - 04/2014]  Refer to  COMPONENTS [04/2014 - 08/2015]  Refer to  COMPONENTS [08/2015 - 08/2017] 

    Result:  1

    A 

    See step  3

  3. REPLACE AIRBAG SENSOR ASSEMBLY 
    1. Replace the airbag sensor assembly (yaw rate and acceleration sensor).

      Refer to COMPONENTS [08/2013 - ]

    See step  4

  4. PERFORM INITIALIZATION 
    NOTE:
    • Performing Reset Memory will clear the learned value of the yaw rate and acceleration sensor (deceleration sensor zero point calibration) and the CVT oil pressure (CVT oil pressure calibration). Make sure to perform Reset Memory, yaw rate and acceleration sensor zero point calibration, and CVT oil pressure calibration when replacing any of the parts shown in the following table:
      Replaced Part
      • Continuously variable transaxle assembly
      • ECM
      • Oil pressure sensor
      • Airbag sensor assembly (Yaw rate and acceleration sensor)
    • After performing Reset Memory, always perform yaw rate and acceleration sensor (deceleration sensor zero point) calibration first, and then CVT oil pressure calibration.
    • Always perform calibration with the vehicle on level ground.
    • Do not shake or vibrate the vehicle during calibration.
    1. Using the Techstream, perform Reset Memory, deceleration sensor zero point calibration and CVT oil pressure calibration.

      Refer to INITIALIZATION [08/2013 - 08/2016]

    2. Check for DTCs again.

      Refer to DTC CHECK / CLEAR [08/2013 - ]
