Caution / Notice / Hint

WARNING: This page is about a different car, the 2024 Lexus TX 550h+. However, it is still accessible from the selected car via links, so may be relevant.

The necessary procedures (adjustment, calibration, initialization or registration) that must be performed after parts are removed and installed, or replaced during shift control actuator assembly removal/installation are shown below.

NECESSARY PROCEDURES AFTER PARTS REMOVED/INSTALLED/REPLACED

Replaced Part or Performed Procedure	Necessary Procedure	Effect/Inoperative Function when Necessary Procedure not Performed	Link
Replacement of shift actuator ECU (Shift control actuator assembly)*1	Perform actuator position learning	Shift position not correctly changing Shift position indicator not illuminating or displaying the incorrect drive state	Refer to UTILITY [12/2023 - ]

*1: Even when not replacing the part, it is necessary to perform the specified necessary procedures after installation.

NOTE:

To prevent the key from being locked in the vehicle, make sure to enter e-latch inspection mode and enable the manual release handle before disconnecting the cable from the negative (-) auxiliary battery terminal.
Refer to INSPECTION MODE PROCEDURE [09/2023 - ]
When disconnecting a wire harness of any component connected to the supply power of the integrated capacitor (integration control supply) or when removing the integrated capacitor (integration control supply), make sure to wait 5 minutes or more after turning the ignition switch off for self-diagnosis to complete and the voltage of the integrated capacitor (integration control supply) to discharge.
If the shift control actuator assembly is replaced or removed, make sure to perform actuator position learning.
If not performed after replacing the shift control actuator assembly, a malfunction such as the shift position not correctly changing, the shift position indicator not illuminating or displaying the incorrect drive state, etc. may occur.
When the shift control actuator assembly is replaced or removed, although the displayed value of Data List item "ACT Position Learning Complete Status" may be "Complete" based on information from before removal, make sure to perform actuator position learning.
When any of the above procedures are completed, change the shift position to all positions and check the following items:
- The shift position indicator illuminates in accordance with the current position.
- The vehicle does not move when in shift state P (parking brake released)
- The vehicle does not drive when in shift state N
- The vehicle drives when in shift state D or R
