The U1173 code is related to the class 2 serial data circuit in automobiles. Modules monitor for serial data communications during normal vehicle operation.

When a critical operating parameter is not received, the module uses a default value for that parameter.

If no message is detected from a learned identification number for 5 seconds, a Diagnostic Trouble Code (DTC) U1173 is set.

This code indicates that there is a lost communication with the power roof module.

What are the possible causes of the u1173 automobile fault code that triggers the engine light or service engine soon warning light?

If you see the engine light or service engine soon warning light on your dashboard, it could be due to the u1173 fault code. This code is triggered by a faulty Power Roof Module (PRM), an open or shorted PRM harness, or a poor electrical connection in the PRM circuit. To fix this issue, you should visually inspect the wiring harness and connectors, check for damaged components, and look for broken, bent, pushed out, or corroded connector’s pins.
