DESCRIPTION
If the back door entry lock function does not operate but the back door open function operates, the communication between the vehicle and key is normal. As a faulty part, the entry lock switch circuit (from the back door opener switch assembly (lock switch) to the certification ECU (smart key ECU assembly)) is suspected.
