Power Liftgate Learn Cycle (Caravan & Town & Country): Description
WARNING: This page does not describe the selected car, but rather 120 other vehicles, including the 2002 Saturn Vue, 2002 Saturn SL2, 2002 Saturn SL1, 2002 Saturn SL, and 2002 Saturn SC2. However, it is still accessible from the selected car via links, so may be relevant.
Any time a power liftgate component is removed, replaced, liftgate adjustment is performed or diagnostic trouble codes are addressed and erased, a learn cycle must be performed. This learn cycle enables the power liftgate control module to learn or relearn its critical information (travel limits, resistance to door travel, etc.) which allows it to perform properly and safely. It also tells the technician that the system is performing properly and is able to be returned to service.
