2016 Chrysler 200 - U110A Code and Electrical Gremlins

Vehicle: 2016 Chrysler 200 Limited

Hi all,

I'm pulling my hair out with my 2016 Chrysler 200 Limited (2.4L). For the past week, I've had intermittent issues where various warning lights come on (ABS, Traction Control, Airbag), and sometimes the radio cuts out or the power windows act up. The car still drives, but it's unsettling.

I finally got a chance to scan it, and the main code coming up is U110A: 'Lost Communication with SCM (Steering Column Module)'. I've checked the battery terminals, and they seem tight. Could this be a bad ground, a wiring harness issue, or something more serious with the module itself?

Any insights from other 200 owners who've dealt with similar electrical problems would be super helpful!

ClearTheCode admin answer:

The U110A code on your 2016 Chrysler 200 Limited (2.4L) indicates a 'Lost Communication with Steering Column Module (SCM)'. This type of U-code points to a communication error within the vehicle's network (CAN bus system), which often manifests as a cascade of seemingly unrelated electrical issues.

  1. Understanding U-Codes: U-codes are network communication codes, meaning a specific module isn't receiving or sending data to other modules as expected. The SCM is crucial for many functions, including steering wheel controls, turn signals, wipers, and often interacts with the body control module (BCM) and powertrain control module (PCM).

  2. Possible Causes for U110A:

    • Faulty SCM: The Steering Column Module itself could be internally faulty, preventing it from communicating.
    • Wiring/Connector Issues: Damaged, corroded, or loose wiring or connectors leading to/from the SCM. This is a very common cause of intermittent communication issues.
    • Power/Ground Issues: The SCM might not be receiving proper power or ground. A weak battery or poor ground connection can disrupt module communication.
    • CAN Bus Interference: Less common, but sometimes other faulty modules or wiring can interfere with the entire network.
    • Software Glitch: In rare cases, a software issue within the module or BCM could cause communication drops.

  3. DIY Checks (If comfortable and safe):

    • Battery Check: Ensure your battery is fully charged and healthy. A weak battery can cause all sorts of phantom electrical issues. Check battery terminals for corrosion and tightness.
    • Visual Inspection of Wiring: Carefully inspect the wiring harness around the steering column and under the dash for any signs of damage, chafing, or loose connections. Look for any signs of water intrusion.
    • Fuse Check: Locate the fuse box (or boxes) and check all fuses related to the steering column, BCM, and other affected systems. A blown fuse to a related module can sometimes cause communication issues.

  4. When to See a Shop:

    • Persistent Issues: If the problem continues after basic checks, or if you're not comfortable with electrical diagnostics.
    • Advanced Diagnostics: A professional shop with a high-end scan tool (like WiTECH for Chrysler) can perform a network scan to identify all modules on the bus, check communication status, and pinpoint exactly where the communication breakdown is occurring. They can also perform continuity tests on wiring.
    • Module Replacement: If the SCM is determined to be faulty, it will likely need replacement and potentially programming, which requires specialized tools and expertise.
