The U1170 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 uses a default value for that parameter. If a module doesn’t receive a Node Alive message from a learned identification number for 5 seconds, a Diagnostic Trouble Code (DTC) U1170 is set. This code specifically indicates that there is a lost communication with the driver door switch assembly.
