Hyundai Tucson: Power Liftgate Module / Inspection

- Inspection Liftgate normal operation transmit / receive process

• FOB key Switch : FOB key Switch → BMC / SMK → CAN communication → PTG Module

• Driver Switch : Driver Switch → Wiring → PTG Module

• Outer Switch : Outer Switch → Wiring → SJB → CAN communication → PTG Module

① Press the power liftgate open switch② Transmit / receive power liftgate open signal via CAN communication and wiring ③ Power liftgate open

• The operation of the power liftgate is activated by mutual communication with the vehicle's module and switch.

• Before replacing parts, it is necessary to check the basic communication, switch signals, and contact points of wire connectors.
