Jeeps are known for their ruggedness and reliability, but sometimes even the most reliable vehicles can have issues. The Jeep U0114 code is an error code related to the Jeep’s communication system. It is caused when the Engine Control Module (ECM) does not receive a Bus Message from the Final Drive Control Module (FDCM). This error code can be caused by an intermittent DTC, CAN bus open or shorted condition, or a faulty FDCM or ECM. To diagnose and resolve this error code, it is important to understand the causes and potential solutions of the Jeep U0114 code.

Jeep U0114 code is an error code that is related to communication system issues in a Jeep. It occurs when the Engine Control Module (ECM) does not receive a Bus Message from the Final Drive Control Module (FDCM). This code can be caused by an intermittent DTC, CAN bus open or shorted condition, or a faulty FDCM or ECM. To properly diagnose and resolve this code, it is important to understand the causes and potential solutions. In this article, we will explore the causes and solutions of the Jeep U0114 code so that you can troubleshoot the problem and get your Jeep back on the road.
Intermittent DTC
The first potential cause of the Jeep U0114 code is an intermittent DTC. An intermittent DTC is a diagnostic trouble code that is not consistently present, but may appear intermittently. This can cause the ECM to not receive a Bus Message from the FDCM. To diagnose this issue, it is important to check for any loose connections or wiring and repair them if necessary.
CAN Bus Open or Shorted Condition
The second potential cause of the Jeep U0114 code is a CAN bus open or shorted condition. CAN stands for Controller Area Network and is a vehicle communication system that is used to control various systems in a vehicle. An open or shorted condition in the CAN bus can cause the ECM to not receive a Bus Message from the FDCM, resulting in the Jeep U0114 code. To diagnose this issue, it is important to check for any open or shorted wiring and repair them if necessary.
Faulty FDCM or ECM
The third potential cause of the Jeep U0114 code is a faulty FDCM or ECM. A faulty FDCM or ECM can prevent the ECM from receiving a Bus Message from the FDCM, resulting in the Jeep U0114 code. To diagnose this issue, it is important to check for any faulty FDCM or ECM and replace them if needed.
Conclusion
The Jeep U0114 code is an error code related to the Jeep’s communication system. It is caused when the Engine Control Module (ECM) does not receive a Bus Message from the Final Drive Control Module (FDCM). To diagnose and resolve this error code, it is important to understand the causes and potential solutions. The causes of the Jeep U0114 code can include an intermittent DTC, CAN bus open or shorted condition, or a faulty FDCM or ECM. The solutions to this issue can include checking for any loose connections, open or shorted wiring, or faulty FDCM or ECM and repairing or replacing them as necessary. With this knowledge, you can troubleshoot the Jeep U0114 code and get your Jeep back on the road.
