Power Liftgate Learn Cycle

Any time a power liftgate component is removed, replaced or a liftgate adjustment is performed, a learn cycle must be performed. This learn cycle enables the power liftgate control module to learn or relearn information (travel limits, resistance to door travel, etc.) which allows it to perform properly and safely. To perform a learn cycle do the following:

1. Connect the diagnostic scan tool.
2. Check for any power liftgate system stored trouble codes, correct and erase any stored codes.
3. Close liftgate.
4. Using the scan tool, select the Power Liftgate Module (PLGM) Menu, Misc Functions tab, then select and run the "Calibrate Liftgate" routine.
5. Follow the on-screen prompts.

In order to obtain conclusive testing of the power liftgate system, the Controller Area Network (CAN) data bus, and all of the electronic modules that provide inputs to, or receive outputs from the power liftgate system components must be checked.
