[SOLVED] Fixing U11C3 Code: Esm-Tcm Communication Loss On Dpt Can

If you see the Engine Light ON or Service Engine Soon Warning Light, it could be due to the automobile fault code: u11c3. This code indicates a problem with the Transmission Control Module (TCM) or Electronic Shift Module (ESM). The cause could be a faulty TCM, open or shorted TCM harness, poor electrical connection, or a faulty ESM.

It is important to address this issue promptly as it can affect the performance of your vehicle. The repair time for this fault code is estimated to be 1.0. To fix the issue, you should visually inspect the related wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.

If you notice the Engine Light ON or Service Engine Soon Warning Light, it could be a sign of u11c3 fault code. Here are the symptoms to look out for:

  • The automobile fault code U11C3 has the following symptoms: Engine Light ON, Service Engine Soon Warning Light ON.

The automobile fault code u11c3 can be caused by a faulty TCM, open or shorted TCM harness, poor electrical connection in TCM circuit, or a faulty ESM.

  • The automobile fault code u11c3 can be caused by a faulty Transmission Control Module (TCM).
  • It can also be caused by an open or shorted Transmission Control Module (TCM) harness.
  • Another cause of this fault code is a poor electrical connection in the Transmission Control Module (TCM) circuit.
  • Lastly, a faulty Electronic Shift Module (ESM) can also cause the u11c3 fault code to appear.

Below are some possible fixes for the automobile fault code u11c3, including inspecting wiring harness and connectors for damage or corrosion.

  • To fix the automobile fault code u11c3, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.
  • This fix will take an estimated repair time of 1.0 hour.

The automobile fault code U11C3 has an estimated repair time of 1.0 hour. The cost of fixing this fault code is influenced by the repair time.

Most auto repair shops charge between $75 and $150 per hour for their services. Therefore, the fixing cost of U11C3 will be between $75 and $150, depending on the repair time required.

The U11C3 fault code is related to the Electronic Shift Module (ESM) in a vehicle. The ESM communicates with other controllers on the Controller Area Network (CAN) Dedicated Powertrain (DPT) bus. If the ESM loses communication with the Transmission Control Module (TCM) on the CAN DPT bus for more than 300ms, the U11C3 code is triggered.

This code indicates a Loss of Communication or CAN bus Off Diagnostic Trouble Code (DTC) has occurred.

What are the possible causes of the u11c3 automobile fault code?

If you’re experiencing the u11c3 fault code, your engine light may be on. This could be due to a faulty Transmission Control Module (TCM), an open or shorted TCM harness, a poor electrical connection in the TCM circuit, or a faulty Electronic Shift Module (ESM). To fix the issue, check the possible causes listed above, visually inspect the related wiring harness and connectors, and look for any damaged components or broken, bent, pushed out, or corroded connector pins.

How can I visually inspect the related wiring harness and connectors to fix the u11c3 fault code?

If you’re experiencing the u11c3 fault code, which is indicated by the engine light being on or the service engine soon warning light, there are a few things you can do to fix it. The possible causes include a faulty Transmission Control Module (TCM), an open or shorted TCM harness, a poor electrical connection in the TCM circuit, or a faulty Electronic Shift Module (ESM). To address these issues, you should visually inspect the related wiring harness and connectors. Look for damaged components and check for broken, bent, pushed out, or corroded connector’s pins.

Is a faulty Electronic Shift Module (ESM) a common cause of the u11c3 fault code?

The u11c3 fault code, indicated by the engine light or service engine soon warning light, can be caused by a faulty Electronic Shift Module (ESM). Other possible causes include a faulty Transmission Control Module (TCM), open or shorted TCM harness, or poor electrical connection in the TCM circuit. To fix the issue, inspect the related wiring harness and connectors for any damage or corrosion, and check for broken or bent connector pins.
