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

When the entry lock and unlock functions do not operate only for the driver door, an error in output request codes from the driver door or malfunction in the front door outside handle assembly is suspected. If the entry functions for the other doors operate normally, then the communication circuit between the key and door control receiver is functioning normally. In this case, radio wave interference or a malfunction in the request code sending circuit (from the certification ECU (smart key ECU assembly) to the front door outside handle assembly (for driver side)) is suspected.
