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