Decoding U1800: Understanding The Mysterious Network Communication Fault
The U1800 code is a Loss of Communication Diagnostic Trouble Code (DTC). It indicates that there is a problem with the Controller Area Network (CAN) serial data circuits.
The code specifically refers to a loss of communication with the Fuel Injector Control Module. This means that the module is not able to exchange operating information and commands with other modules. The cause of the problem could be a malfunction in the CAN circuit or a loss of power during the current ignition cycle.
If any of the CAN circuits are shorted to battery voltage, ground, or between them, no communication is possible on the CAN serial data bus, and a Diagnostic Trouble Code will set.
