Experiencing an OBDII test failure on your Dodge Stratus, particularly encountering a U110C code? You’re not alone. Modern vehicles like the Dodge Stratus rely on sophisticated onboard diagnostic systems, and when things go wrong, the OBDII system is your first line of defense. This guide will help you understand OBDII error codes, focusing on the U110C code, and provide steps to troubleshoot potential issues. While the original article provided a comprehensive list of OBDII codes for Chrysler and Dodge vehicles, we aim to delve deeper and offer more targeted information, especially concerning OBDII test failures and communication errors like U110C in models like the Dodge Stratus.
Decoding OBDII Error Codes on Your Dodge Stratus
Before diving into the specifics of the U110C code, let’s understand how to retrieve generic OBDII fault codes from your Chrysler or Dodge vehicle. This method is particularly applicable to models manufactured between 2001 and 2007, including the Dodge Stratus.
Step-by-Step Guide to Retrieve OBDII Codes:
This simple key-cycling method allows you to display engine fault codes directly on your odometer, without needing a scan tool for initial code retrieval.
- Step 1: Key Position OFF: Ensure your ignition key is in the “OFF” position.
- Step 2: Cycle to ON Position: Turn the ignition key to the “ON” position, just before starting the engine. You should see the dashboard indicator lights illuminate.
- Step 3: Repeat the Cycle (3 Times): Quickly repeat the “OFF-ON” sequence three times within 5 seconds (OFF-ON, OFF-ON, OFF-ON). Do not start the engine.
- Step 4: Read the Error Codes: Observe the odometer display. Error codes will appear in the format PXXXX, where X is a digit from 0 to 9.
Example: If you see “P0136”, referring back to the comprehensive list, this indicates an issue with the O2 sensor (Bank 1 Sensor 2).

Understanding the U110C Code: Lost Communication with Transmission Control System
Now, let’s address the primary keyword focus: “Obdii Test Fail Dodge Stratus U110c”. The U110C code is a network communication error code, and it stands for “Lost Communication With Transmission Control System”. This code is not directly listed in the original article’s P-codes, as U-codes pertain to network communication issues, often within the Body Control Module (BCM) or related systems.
What Does U110C Mean?
The U110C code indicates that your Dodge Stratus’s Engine Control Module (ECM) has lost communication with the Transmission Control System (TCM). These modules communicate over a network, often a CAN bus (Controller Area Network). When this communication is disrupted, the U110C code is triggered.
Potential Causes of U110C Code in Dodge Stratus:
- CAN Bus Issues: Problems within the CAN bus network itself, such as wiring faults (shorts, opens, or corrosion), connector issues, or termination problems.
- TCM Malfunction: A faulty Transmission Control Module can fail to communicate.
- ECM/PCM Issues: Less commonly, issues with the Engine Control Module (also sometimes referred to as Powertrain Control Module – PCM) can cause communication failures.
- Wiring and Connections: Damaged wiring harnesses, loose connections, or corrosion in the wiring or connectors related to the TCM or CAN bus.
- Power Supply Problems: Insufficient or unstable power supply to the TCM or ECM.
- Software/Firmware Glitches: In rare cases, software or firmware issues within the modules can lead to communication problems.
Troubleshooting Steps for U110C Code:
- Visual Inspection: Begin with a thorough visual inspection of wiring harnesses and connectors related to the TCM and ECM. Look for any signs of damage, corrosion, or loose connections. Pay close attention to the CAN bus wiring if you can identify it (typically twisted pair wiring).
- Check TCM and ECM Connectors: Carefully disconnect and reconnect the connectors to the TCM and ECM, ensuring they are clean and properly seated. Use contact cleaner if necessary.
- Battery and Power Supply Check: Verify the battery voltage and ensure the charging system is functioning correctly. Low voltage can sometimes cause communication issues.
- CAN Bus Diagnostic Tools: Advanced diagnostics often require tools that can test the CAN bus network. Professional scan tools, like those from Autel, can perform network scans and identify communication faults.
- TCM Testing: If possible, test the TCM independently. However, this often requires specialized equipment and knowledge.
- Consult a Professional: Due to the complexity of network communication issues, if basic troubleshooting steps don’t resolve the U110C code, it’s advisable to consult a qualified automotive technician. They have the expertise and diagnostic tools to pinpoint the exact cause and perform necessary repairs.
Comprehensive List of OBDII Error Codes for Chrysler & Dodge (2001-2007)
While the U110C code is a U-code and not in the original P-code list, understanding the range of potential P-codes is still valuable for diagnosing engine-related issues in your Dodge Stratus or other Chrysler/Dodge vehicles from this era. Below is an extended list based on the original article, covering P-codes, B-codes (Body), and C-codes (Chassis) for a more complete reference.
