Chevrolet U1098: Loss of HUD Communications
OVERVIEWWhat Does The Chevrolet U1098 Code Mean?
Modules connected to the class 2 serial data circuit monitor for serial data communications during normal vehicle operation. Operating information and commands are exchanged among the modules. When a module receives a message for a critical operating parameter, the module records the identification number of the module which sent the message for the state of health monitoring/node alive messages.
A critical operating parameter is one which, when not received, requires that the module use a default value for that parameter. Once an identification number is learned by a module, it will monitor for that module node alive message. Each module on the class 2 serial data circuit is required to send a Node Alive message every 2 seconds. When no message is detected from a learned identification number for 5 seconds, a Diagnostic Trouble Code (DTC) U1098 is set.
What Are The Potential Causes Of The Chevrolet U1098 Code?
- Faulty Head-Up Display (HUD)
- Head-Up Display harness is open or shorted
