The U1161 fault code is related to the class 2 serial data circuit in automobiles. Modules in the circuit monitor for serial data communications during normal vehicle operation. When a module doesn’t receive a message for a critical operating parameter, it records the identification number of the module which sent the message for the state of health monitoring.

If no message is detected from a learned identification number for 5 seconds, a Diagnostic Trouble Code (DTC) U1161 is set.

This fault code specifically indicates that there is a lost communication with the front passenger door module.
