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