Unlocking The Mystery Of U1818: Your Car’s Electrical System Alert
The U1818 code is related to the powertrain high-speed General Motor Local Area Network (GMLAN) serial data circuits. Devices connected to this network monitor for serial data communications during normal vehicle operation.
The code is triggered when a supervised periodic message that includes the transmitter device availability has not been received.
This means that there is a lost communication with the engine control module on powertrain expansion communication bus.
The Diagnostic Trouble Code (DTC) will set when this happens.
