Driver Side Door Entry Lock and Unlock Functions do not Operate: Description

If the entry lock and unlock functions do not operate for the driver side door only, the request code may not be being transmitted from the driver side door or the front door outside handle assembly LH (touch sensor) may be malfunctioning. If the entry functions for other doors operate properly, communication between the electrical key transmitter sub-assembly and door control 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 front door outside handle assembly LH (driver side electrical key antenna), or there may be wave interference.
