If you own a Chrysler vehicle and you’re experiencing a “Lost Communication with SCM (SAS)” error code (U110A), then you’re in the right place. This code can be caused by a variety of issues, from something as simple as a loose connection to a more serious problem such as a faulty Steering Column Control Module or Totally Integrated Power Module (TIPM). To help you identify the source of the problem and provide you with solutions, we’ve put together an overview of the different causes and solutions related to Chrysler Code U110A.
Causes and Solutions for U110A Code
| Cause | Solution |
|---|---|
| CAN C BUS OPEN OR SHORTED CONDITION | Check for open or shorted wiring, replace electrical connectors and repair any wiring problems. |
| STEERING COLUMN CONTROL MODULE | Replace the steering column control module and retest the system. |
| TOTALLY INTEGRATED POWER MODULE (TIPM) | Replace the TIPM and retest the system. |
| POWERTRAIN CONTROL MODULE (PCM) | Replace the PCM and retest the system. |
CAN C BUS OPEN OR SHORTED CONDITION
A Chrysler Code U110A can be caused by a CAN C BUS open or a shorted condition. This is a simple issue and can be easily diagnosed. All that is needed is a thorough inspection of the wiring. If there is a problem, like an open or a shorted wiring, then the connectors must be replaced and the wiring repaired.
STEERING COLUMN CONTROL MODULE
Another possible cause for the U110A code is a faulty Steering Column Control Module. This is a more serious issue and requires the Module to be replaced in order to resolve the problem. After replacing the Module, the system must be tested again to make sure the code does not return.
TOTALLY INTEGRATED POWER MODULE (TIPM)
A faulty Totally Integrated Power Module (TIPM) can also cause the U110A code to be displayed. If the TIPM is malfunctioning, then it must be replaced. Once the replacement is complete, the system must be tested again to make sure the code does not return.
POWERTRAIN CONTROL MODULE (PCM)
The last potential cause for the U110A code is a faulty Powertrain Control Module (PCM). If the PCM is malfunctioning, then it must be replaced. After the replacement is complete, the system must be tested again to make sure the code does not return.
Conclusion
The Chrysler Code U110A can be caused by a variety of issues, from something as simple as a loose connection to a more serious problem such as a faulty Steering Column Control Module or Totally Integrated Power Module (TIPM). The best way to identify the source of the problem and provide solutions is to inspect the wiring, replace any faulty components, and retest the system. The best way to ensure that a Chrysler Code U110A does not return is to address the issue promptly and follow the steps outlined above to diagnose the issue and repair any faulty components.
