Code U114D Jeep Description

The diagnostic code U114D indicates a loss of communication between the Body Control Module (BCM) and the Hands Free Release Module (HFRM) in a Jeep vehicle. This communication occurs over a Local Interconnect Network (LIN) bus, which is a low-speed network used for communication between various modules in the vehicle. When the BCM fails to receive messages from the HFRM for more than 7.5 seconds while the ignition is on and the system voltage is normal, this code is triggered. The hands-free liftgate feature, which allows users to open the liftgate without using their hands, may become inoperative as a result of this communication failure.
