The switch/sensor or actuator for the rear door may be damaged or out of place.The switch is located on the High Voltage Power Supply (Part# WH773).

Here is a video that explains this error and shows you how to replace it. This will fix this problem 90% of the time, just make sure you set the HVPS correctly on TOP of the actuator (plastic piece that hits the switch). If for some reason this does not work, check that the actuator is not broken and try reseating the HVPS and try again. Hope this helps. Good luck!
