Rear Door LH Entry Lock and Unlock Functions do not Operate [11/2021 - ]: Description

If the entry lock and unlock functions do not operate for the rear door LH only, the request code may not be being transmitted from the rear door LH or the rear door outside handle assembly (for driver side) (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 monitoring system receiver assembly 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 (for driver side) (electrical key antenna)), or there may be wave interference.
