Code U114D Dodge Description
The diagnostic trouble code U114D indicates that the Body Control Module (BCM) has lost communication with the Hands Free Release Module (HFRM). This communication is facilitated through a Local Interconnect Network (LIN) bus, which is a low-speed network used for communication between various electronic modules in the vehicle. When the BCM does not receive any messages from the HFRM for a duration exceeding 7.5 seconds while the ignition is in the ON position and the system voltage is within the normal operating range, this code is triggered. The hands-free liftgate functionality, which allows the user to open the liftgate without using their hands, may become inoperative as a result of this code being set.
Common Causes of U114D Dodge
- Open or shorted Fused B(+) circuit to the Hands Free Release Module
- Open ground circuit to the Hands Free Release Module
- Open LIN bus communication circuit
- Poor electrical connection at the Hands Free Release Module
- Corroded, loose, or damaged connector terminals
Symptoms of U114D Dodge

- Check the LIN bus communication circuit for continuity and proper connections.
- If necessary, replace the Hands Free Release Module if it is determined to be faulty.
- Clear the diagnostic trouble codes and perform a function test to verify that the hands-free liftgate operates correctly.
Cost to Fix U114D Dodge
The cost to diagnose and repair the U114D code can vary significantly based on the specific issue identified.
