8. Register the compensation code.
   1. Press "Input".
   2. Manually input the transaxle compensation code. The code is a 60-digit alphanumeric value printed on the QR label. After inputting the code, press "OK".
9. Check that the compensation code displayed on the screen is correct by comparing it with the 60-digit alphanumeric value on the QR label.
   NOTE:

   If an incorrect transaxle compensation code is input into the ECM, shift shock will occur.

10. Press "NEXT" to set the compensation code to the ECM.

    HINT: 

    • If the registration process fails, the compensation code may be incorrect. Check the compensation code again.
    • If the attempted compensation code is correct, a problem with the wire harness or a bad connection with the DLC3 may cause a registration failure. Check the wire harness and the DLC3 connection. If no problem is found, the ECM may be malfunctioning. Check the ECM and repeat this operation.
11. Press "EXIT".
