ENTRY AND START SYSTEM (for Entry Function) - Back Door Entry Lock Function does not Operate


DESCRIPTION

If the entry lock function does not operate for the back door only, but the entry unlock function operates, the request code is being transmitted properly from the back door. In this case, there may be a problem related to the lock switch (connection between the back door opener switch assembly and certification ECU [smart key ECU assembly]).
