The U1168 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 U1168 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.
