|U1807 GMC code descriptionThe high voltage energy management high-speed General Motor Local Area Network (GMLAN) serial data circuits are serial data buses used to communicate information between the Hybrid Powertrain Control Module 2, the Battery Energy Control Module, and the Battery Charger. If this serial data system is inoperative the devices will not communicate with each other on this bus, but they still communicate with the scan tool through high-speed GMLAN bus.
The scan tool does not communicate with devices through the high voltage energy management high-speed GMLAN bus. The high voltage energy high-speed GMLAN serial data circuits connect directly to the auxiliary data connector and do not connect with the scan tool.
The Diagnostic Trouble Code (DTC) will set when the device setting the DTC has attempted to establish communications on the serial data circuits for more than 1.4 seconds without success.
