U1221: Understanding The Abs Control Module Communication Fault
The U1221 code is related to the class 2 serial data circuit in automobiles. Modules monitor serial data communications among themselves during normal vehicle operation. If a module does not associate an identification number with at least one critical parameter within 5 seconds of beginning serial data communication, the U1221 code is set.
This code specifically indicates invalid or missing data for interior lamp outage.
