Power Liftgate Learn Cycle

WARNING: This page is about a different car, the 2005 Dodge Grand Caravan, 2005 Dodge Caravan, and 2005 Chrysler Town & Country. However, it is still accessible from the selected car via links, so may be relevant.

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. Perform the following to complete a power liftgate learn cycle:

Obtain a DRBIII®, or equivalent scan tool.
Connect the scan tool to the vehicle and check for any power liftgate system stored Diagnostic Trouble Codes (DTCs), correct and erase any stored DTCs.
Using the scan tool, Go into Test Routine Menu and select the power open command.
Select the power close command.
The liftgate learn cycle is complete.

If a DRBIII® or equivalent scan tool is not available, the learn cycle can be performed by actuating the liftgate using any of the normal command switches. Be certain to cycle the liftgate through a complete open and close cycle before returning the vehicle to service.

NOTE: If the power liftgate will not complete a full cycle a problem exists with the power liftgate system. (Refer to ELECTRICAL/POWER DOORS - DIAGNOSIS AND TESTING) .
