Unlocking The Mystery Of U1066: A Guide To Diagnosis
The U1066 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) U1066 is set. This code indicates a loss of communication with the rear integrated module.
