ADDITIONAL INFORMATION
Introduction
Some 2012 – 2013 model year RX 350 or RX 450h vehicles may display a “Back Door Open” or “Key
Detected in Vehicle” warning message intermittently on the combination meter while the vehicle is
in motion. This message may be triggered if the courtesy switch in the back door lock assembly
intermittently changes to the door open position while the hatch is in the closed position. A new back
door lock assembly is available to address this condition.
NOTE
This repair procedure applies ONLY to vehicles with an intermittent and difficult-to-reproduce
condition. If the condition can be easily reproduced, the back door lock assembly may not be the
root cause. Per the Repair Manual, two other vehicle subsystems may cause this condition or a
condition similar to it: the combination meter or the main body ECU. Follow the appropriate Repair
Manual procedures to diagnose those systems.
