U1861: Unveiling The Mystery Behind Your Car’s Electrical System
The U1861 fault code indicates a loss of communication between the Battery Charger Control Module and the Engine Control Module. Modules connected to the Controller Area Network (CAN) serial data circuits monitor for serial data communications during normal vehicle operation. If any of the CAN circuit are shorted to battery voltage, ground, or between them no communication is possible on the CAN serial data bus, a Diagnostic Trouble Code will set.
A module with a CAN serial data circuits malfunction or which loses power during the current ignition cycle will have a Loss of Communication Diagnostic Trouble Code (DTC) set by other modules that depend on information from that failed module.
