  8. 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.
