Power Liftgate Learn Cycle (Caravan & Town & Country): Procedure

  1. Connect the DRBIII® scan tool to the Data Link Connector (DLC), located on lower left edge of instrument panel. Turn ignition switch to ON position. Check for power liftgate door codes (fault messages). Clear any DTCs that are set.
  2. Operate power liftgate and recheck for DTCs. If any DTCs exist, diagnose and repair as necessary before performing the learn cycle. See appropriate BODY CONTROL MODULES article in ACCESSORIES & EQUIPMENT.
  3. If DRBIII® scan tool is not available, the learn cycle can be performed by opening and closing the power liftgate using any of the normal open/close command switches. Be certain to cycle the liftgate through a complete open and close cycle or the procedure will not be complete.
  4. Using the DRBIII®, go into the Test Routine Menu and select a power open command.
  5. Using the DRBIII®, select a power close command.
  6. The power liftgate learn cycle is complete. If power liftgate door does not fully open or close, a problem still exists. Diagnose and repair as necessary.
