Automatic Transaxle System: Registration

NOTE:

When the automatic transaxle is replaced, the transaxle compensation code must be input into the TCM (Proceed to step 1). After the automatic transaxle is reinstalled, the QR code label will be positioned where the code cannot be read. Therefore, before reinstalling the automatic transaxle, record the transaxle compensation codes or input them in the intelligent tester.
When the TCM is replaced, the existing transaxle compensation codes must be input into the new TCM (Proceed to step 2).

INPUT TRANSAXLE COMPENSATION CODE INTO TCM
NOTE: Transaxle compensation codes are unique, 60-digit alphanumeric values printed on the QR label. If an incorrect transaxle compensation code is input into the TCM, shift shock may occur.
1. Record the transaxle compensation code specified on the QR label.
  HINT:
  
  The transaxle compensation code is imprinted on the QR label.
2. Shift the shift lever to the N or P position.
3. Connect the intelligent tester to the DLC3.
4. Turn the engine switch on (IG).
5. Turn the tester on.
  NOTE: Do not start the engine.

  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 TCM may be malfunctioning. Check the TCM and repeat this operation.
