Decoding U1806: Understanding Your Car’s Electrical System
The U1806 code is related to the high voltage energy management high-speed GMLAN serial data circuits in automobiles. These circuits are 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 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.
