Back Door Entry Lock Function does not Operate: Description

WARNING: This page is about a different car, the 2010 Toyota 4Runner. However, it is still accessible from the selected car via links, so may be relevant.

If the back door entry lock function does not operate but the back door unlock function operates, the communication line between the vehicle and electrical key transmitter is normal. The entry lock switch circuit (back door control switch → certification ECU) may be faulty.
