The U1047 code is related to the class 2 serial data circuit in automobiles. Modules monitor serial data communications during normal vehicle operation. If a module does not associate an identification number with at least one critical parameter within 5 seconds, the U1047 code is set.

This code indicates that there is invalid or missing data for primary I.

It is a critical operating parameter that, when not received, requires the module to use a default value for that parameter.
