Rear Door RH Entry Lock and Unlock Functions do not Operate [06/2018 - ]: Description
WARNING: This page does not describe the selected car, but rather 10 other vehicles, including the 2024 Lexus ES 350, 2024 Lexus ES 250, 2023 Lexus ES 350, 2023 Lexus ES 250, and 2022 Lexus ES 350. However, it is still accessible from the selected car via links, so may be relevant.
If the entry lock and unlock functions do not operate for the rear door RH only, the request code may not be being transmitted from the rear door RH or the rear door outside handle assembly RH (touch sensor) may be malfunctioning. If the entry functions for other doors operate properly, communication between the electrical key transmitter sub-assembly and electrical key and tire pressure warning ECU and receiver is normal. In this case, there may be a problem with request code transmission (communication between the certification ECU (smart key ECU assembly) and rear door outside handle assembly RH (electrical key antenna)), or there may be wave interference.
