Caution / Notice / Hint

WARNING: This page is about a different car, the 2025 Lexus NX 350h, 2024 Lexus NX 350h, 2023 Lexus NX 350h, and 2022 Lexus NX 350h. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
  • If initialization and learning of the shift control actuator assembly (shift actuator ECU) has not been performed, this DTC may be stored. If the shift control actuator assembly (shift actuator ECU) is replaced or removed, make sure to perform actuator position learning.

    Refer to UTILITY [11/2021 - ]

  • When removing or installing the shift control ECU or shift actuator ECU, make sure there is no power supplied*1 when disconnecting or connecting the connectors.

    *1: Auxiliary battery, sub-battery, integrated capacitor, etc.

  • This DTC may be stored if the auxiliary battery voltage is abnormal. Confirm the connection condition of the auxiliary battery before inspection.
  • When disconnecting a wire harness of any component connected to the supply power of the integrated capacitor or when removing the integrated capacitor, 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 to discharge.
  • Before performing troubleshooting, check the fuses, connector connections and contact pressure of the relevant terminals for this circuit.
  • 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.
