Checking the wiring and component
Power Operated Tailgate Module (POT) controls the hydraulic operation of the tailgate. If the hydraulic pump does not work this indicates open circuit, short-circuiting to ground/voltage, relay problem in module or that the pump has failed.
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).
