Rear Door RH Entry Lock Function does not Operate [08/2013 - ]: Description
WARNING: This page is about a different car, the 2014 Lexus ES 300h. However, it is still accessible from the selected car via links, so may be relevant.
If the entry lock function does not operate for the rear door RH only, but the entry unlock function operates, the request code is being transmitted properly from the rear door RH. In this case, there may be a problem related to the rear door outside handle assembly RH (for rear door RH) (lock sensor) (connection between the certification ECU (smart key ECU assembly) and rear door outside handle assembly RH (for rear door RH) (lock sensor)).
