WARNING: This page is about a different car, the 2024 Kia Sorento. However, it is still accessible from the selected car via links, so may be relevant.
In an open signal with the tailgate fully closed, the PTGM transmits a latch open command via a CAN message to the ICU. The ICU drives the latch release motor when entering the latch open signal.
