Code U2409 GMC Description

The high-speed General Motors Local Area Network (GMLAN) serial data circuits are serial data buses used to communicate information between the devices. The high-speed GMLAN serial data circuits also connect directly to the X84 Data Link Connector (DLC) for programming purposes. If this serial data system is inoperative, some devices may still be able to communicate with the scan tool due to other serial data systems but not with each other. The device setting the Diagnostic Trouble Code (DTC) has attempted to establish communications on the high-speed GMLAN serial data circuits more than 3 times.
