Checking the wiring and component

Check the cables for open circuit and short-circuiting to ground/voltage.
If the leads are intact, replace Power Operated Tailgate Module (POT) and its hydraulic parts.
Remedy as necessary.

Checks after replacement
Check that the latest software is in the module by downloading an upgrade for Power Operated Tailgate Module (POT).
