Caution / Notice / Hint

WARNING: This page is about a different car, the 2025 Toyota Highlander, 2024 Toyota Highlander, and 2023 Toyota Highlander. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • When the automatic transaxle assembly is replaced, the transaxle compensation code must be registered to the ECM (proceed to Procedure 1).

    After the automatic transaxle assembly is installed, the Quick Response (QR) code label will be positioned where the code cannot be read. Therefore, before installing the automatic transaxle assembly, record the transaxle compensation code or register it using the GTS.

  • When the ECM is replaced, the existing transaxle compensation code must be registered to the new ECM (proceed to Procedure 2).
  • Perform Reset Memory (AT initialization) after replacing the automatic transaxle assembly, transmission valve body assembly, any of the solenoid valves or engine assembly.
