U0001 GMC MeaningDevices connected to the General Motors Local Area Network (GMLAN) serial data circuits monitor for serial data communications on the GMLAN network during normal vehicle operation. Operating information and commands are exchanged among the devices. Each device on GMLAN network maintains a transmit error counter and a receive error counter. The counter values increase with detected errors and will decrease with error-free messages. If the transmit error counter value exceeds 255 the device removes itself from the network and a Diagnostic Trouble Code (DTC) U0001 will be set.
