Code U114D Chrysler Description
The diagnostic code U114D indicates that the Body Control Module (BCM) has lost communication with the Hands Free Release Module (HFRM). This communication occurs over a Local Interconnect Network (LIN) bus, which is a low-speed network designed for communication between various vehicle modules. 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 stable, this code is triggered. The primary function of the HFRM is to enable hands-free operation of the liftgate, allowing users to open or close the liftgate without using their hands, which is particularly useful when carrying items.
Common Causes of U114D Chrysler
- 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 Chrysler
- Engine Light ON (or Service Engine Soon Warning Light)
- Inoperative hands-free liftgate functions
- Liftgate not responding to remote or key fob commands
- Intermittent operation of the liftgate
- Other electrical anomalies in the vehicle, such as flickering lights or malfunctioning accessories
How to Fix U114D Chrysler
- Perform a visual inspection of the HFRM and BCM wiring harness for damage or corrosion.
- Test the power and ground circuits to the Hands Free Release Module to ensure they are functioning correctly.
- Check the LIN bus communication circuit for continuity and proper voltage levels.
- Inspect and clean connector terminals to ensure a secure connection.
- If no issues are found, consider replacing the Hands Free Release Module or the Body Control Module, depending on the diagnosis.
Cost to Fix U114D Chrysler
The cost to diagnose and repair the U114D code can vary significantly based on the specific issues found and the labor rates in your area.
