The Chrysler U1110 code is an error code that can indicate a serious problem with the vehicle’s electronic system. This code is usually triggered when the Electronic Pedestrian Protection Module (EPPM) fails to receive the vehicle speed signal over the CAN C bus from the Anti-lock Brake Module (ABS), Electronic Stability Program (ESP), and Electronic Stability Control (ESC). This Chrysler U1110 Code can cause a variety of issues with the vehicle’s performance and stability, which can range from minor problems to major safety concerns. In this article, we will discuss the causes, effects, and solutions to this code and how to deal with it.
Causes and Solutions for Chrysler U1110 Code
| Causes | Solutions |
|---|---|
| CAN C BUS CIRCUIT OPEN OR SHORTED | Check the wiring for the CAN C Bus circuit for any signs of damage or wear. |
| ELECTRONIC STABILITY PROGRAM (ESP)/ANTILOCK BRAKE MODULE (ABS) | Replace the ESP or ABS module if necessary. |
| ELECTRONIC PEDESTRIAN PROTECTION MODULE (EPPM) | Replace the EPPM module if necessary. |
| Related Service Bulletins | Refer to the related service bulletins for further instructions. |
CAN C Bus Circuit Open or Shorted
When the Chrysler U1110 code is triggered, it is usually caused by a CAN C Bus circuit that is either open or shorted. The CAN C Bus is a communication network that connects all of the vehicle’s electronic modules and components. If the circuit is open or shorted, it can cause the EPPM to be unable to receive the vehicle speed signal. This can lead to a variety of issues with the vehicle, ranging from minor issues to major safety concerns.
Electronic Stability Program (ESP) or Antilock Brake Module (ABS)
If the CAN C Bus circuit is not the cause of the Chrysler U1110 code, then it is likely that the ESP or ABS module is faulty. If either of these modules is malfunctioning, it can cause the EPPM to be unable to receive the vehicle speed signal. In this case, it is recommended that the ESP or ABS module be replaced.
Electronic Pedestrian Protection Module (EPPM)
In some cases, the EPPM itself may be the cause of the U1110 code. If the EPPM is malfunctioning, it can cause the vehicle speed signal to be unable to be received. In this case, it is recommended that the EPPM module be replaced.
Related Service Bulletins
In some cases, the Chrysler U1110 code may be caused by a related service bulletin. Service bulletins provide additional information on how to diagnose and repair the issue. It is recommended that the related service bulletins be referred to for further instructions.
Conclusion
The Chrysler U1110 code is an error code that can indicate a serious problem with the vehicle’s electronic system. This code is usually triggered when the Electronic Pedestrian Protection Module (EPPM) fails to receive the vehicle speed signal over the CAN C bus from the Anti-lock Brake Module (ABS), Electronic Stability Program (ESP), and Electronic Stability Control (ESC). This Chrysler U1110 Code can cause a variety of issues with the vehicle’s performance and stability, which can range from minor problems to major safety concerns. The causes and solutions for this code include a CAN C Bus circuit that is open or shorted, a faulty ESP or ABS module, a faulty EPPM module, and related service bulletins. By understanding the causes, effects, and solutions to this code, one can effectively diagnose and repair the issue.
