Normal Power Tailgate Operation, Transmission/Reception Process

Key FOB switch: Key FOB switch → BCM / SMK → CAN communication → PTG module Driver switch: Driver switch → wiring → PTG module Exterior switch: Exterior switch → wiring → SJB → CAN communication → PTG module

① Press the power liftgate open button. ② Transmit/receive the power liftgate open signal via CAN bus and wiring. ③ Power liftgate opens.

Power liftgate operation is activated by mutual communication between the vehicle module and the switches. Before replacing parts, check the main communication, switching signals, and connector terminal contact points.
