[SOLVED] Fixing U11C2: Transmission Message Lost

If you see the engine light on or the service engine soon warning light, it could be due to the automobile fault code U11C2.

This code indicates a problem with the Transmission Control Module (TCM) or its related components. The possible causes include a faulty TCM, an open or shorted TCM harness, poor electrical connection in the TCM circuit, or a faulty Powertrain Control Module (PCM). The repair time for this fault code is 1.0, and it is important to address the issue promptly to avoid further damage to your vehicle.

To fix the problem, 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, it could be a sign of u11c2 fault code. Here are the symptoms to look out for:

  • The U11C2 fault code in an automobile can cause several symptoms, including the engine light turning on or the service engine soon warning light appearing.
  • Other symptoms may include issues with the transmission, such as difficulty shifting gears or the transmission slipping.
  • The vehicle may also experience reduced power or acceleration, stalling, or rough idling.
  • Additionally, the fuel efficiency may decrease, and there may be issues with the vehicle’s emissions.
  • It is important to address these symptoms promptly to prevent further damage to the vehicle.

The automobile fault code u11c2 can be caused by a faulty TCM, TCM harness issues, poor electrical connections, or a faulty PCM.

  • The automobile fault code u11c2 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 Powertrain Control Module (PCM) can also cause the u11c2 fault code to appear.

Below are the possible fixes for the automobile fault code u11c2, including inspecting wiring harness, connectors, and damaged components.

  • To fix the automobile fault code u11c2, first, check the possible causes listed above.
  • Then, visually inspect the related wiring harness and connectors.
  • Look for any 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 U11C2 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 U11C2 will be between $75 and $150, depending on the repair time required.

The u11c2 fault code is related to the communication between the Powertrain Control Module (PCM) and the Transmission Control Module (TCM) in an automobile.

This code is triggered when the PCM does not receive a message from the TCM for around 500ms. The Diagnostic Trouble Code (DTC) sets when this happens, indicating a lost transmission message.

This fault code can cause issues with the transmission and may result in poor vehicle performance. It is important to address this issue promptly to avoid further damage to the vehicle.

What are the possible causes of the u11c2 automobile fault code?

If you’re experiencing the u11c2 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 Powertrain Control Module (PCM). 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 u11c2 fault code?

If you’re experiencing the u11c2 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 Powertrain Control Module (PCM). 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 Powertrain Control Module (PCM) a common cause of the u11c2 fault code?

While a faulty Powertrain Control Module (PCM) is listed as a possible cause of the u11c2 fault code, it is not a common one. The most common cause is a faulty Transmission Control Module (TCM), followed by issues with the TCM harness or circuit connections. To fix the issue, it is recommended to visually inspect the wiring harness and connectors for any damage or corrosion, and check for broken or bent pins.
