Code U183E 2017 GMC Sierra Description

The serial data circuit is the means by which the devices in the vehicle communicate with each other. Once the scan tool is connected to the serial data circuit through the Data Link Connector (DLC), the scan tool can be used to monitor each device for diagnostic purposes and to check for Diagnostic Trouble Codes (DTC). When the vehicle is ON, each device communicating on the serial data circuit sends a state of health message to ensure that the device is operating properly. When a device stops communicating on the serial data circuit, for example, if the device loses power or ground, the state of health message it normally sends on the serial data circuit disappears. Other devices on the serial data circuit, which expect to receive that state of health message, detect its absence; those devices in turn set a DTC associated with the loss of state of health of the non-communicating device. A loss of serial data communications DTC does not represent a failure of the devices that contain the stored DTC.

Frequently Asked Questions about U183E 2017 GMC Sierra Code

1. What does the OBDII code U183E mean on a 2017 GMC Sierra?

This code indicates that the vehicleâ€™s systems have lost communication with the Telematics Communication Interface Control Module (TCICM) on the low-speed CAN bus.

2. What are the common symptoms of code U183E in a 2017 GMC Sierra?

Symptoms include OnStar or telematics system malfunctions, warning lights on the dashboard, or a lack of communication with the telematics module during diagnostics.

3. What causes the U183E code to appear in a 2017 GMC Sierra?

The most common causes are wiring issues, a faulty TCICM, a poor connection at the module, or a malfunction in the low-speed CAN bus network.

4. Can a bad battery cause the U183E code?

Yes, a weak or failing battery can cause communication errors, including the U183E code, due to inconsistent voltage supply to the module.

5. How do I diagnose the U183E code in a 2017 GMC Sierra?

Start by checking the wiring and connectors for damage or corrosion, inspect the low-speed CAN bus network, and test the TCICM for proper operation.

6. What tools are needed to troubleshoot the U183E code?

Youâ€™ll need a scan tool capable of reading manufacturer-specific codes, a multimeter for testing circuits, and possibly a wiring diagram for the telematics system.

7. Can I drive my 2017 GMC Sierra with a U183E code?

While the vehicle may still be drivable, systems like OnStar or telematics features may not function properly, which could be a safety concern in certain situations.

8. How do I fix the U183E code on my 2017 GMC Sierra?

Repairs might involve replacing the TCICM, repairing damaged wires or connectors, or addressing issues in the low-speed CAN bus network.

9. How much does it cost to repair a U183E code?

The cost can vary depending on the issue, but repairing wiring or connectors may cost less than $200, while replacing the TCICM can cost $500â€“$1,000 or more.

10. Can a software update fix the U183E code?

In some cases, a software update for the telematics module or other related systems may resolve communication issues, especially if the module is not defective.
