The automobile fault code U1111 indicates a problem with the Instrument Cluster Communication Circuit. The most common symptom is the Engine Light ON or Service Engine Soon Warning Light.
The cause of this fault code could be a faulty instrument cluster, an open or shorted instrument cluster harness, a poor electrical connection in the instrument cluster circuit, or a faulty Transmission Control Module (TCM). The repair importance is high as it affects the communication between the instrument cluster and other modules in the vehicle.
The repair difficulty is moderate, and the repair time is estimated at 1.0 hour. To fix the issue, one 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. It is essential to interpret the fault code correctly to avoid further damage to the vehicle.

Decoding U1111: Understanding The Lost Communication With Vehicle Dynamics Control Module
The U1111 fault code is a Diagnostic Trouble Code (DTC) that sets when the odometer signal is not available for more than 3 seconds. The Instrument Cluster reports this via a CAN message. Alternatively, the Transmission Control Module (TCM) may detect that the odometer value has not changed after receiving a certain number of pulse signals from the output speed sensor.
The U1111 code is also known as the Lost Odometer Message.
FAQ
If you see the engine light or service engine soon warning light on your dashboard, it could be due to the u1111 fault code. This code is usually caused by a faulty instrument cluster, an open or shorted instrument cluster harness, poor electrical connection in the instrument cluster circuit, or a faulty transmission control module (TCM). To fix this 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’re experiencing the u1111 automobile fault code, which is indicated by the engine light being on, it could be due to a faulty instrument cluster, an open or shorted instrument cluster harness, a poor electrical connection in the instrument cluster circuit, or a faulty transmission control module.
