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

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