The U1862 fault code is related to the Battery Energy Control Module. It indicates that there is a loss of communication between the Battery Energy Control Module and the Serial Data Gateway Module. This loss of communication can occur due to a malfunction in the CAN serial data circuits or if the module loses 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.

It is important to address this issue promptly to ensure proper communication among the modules and prevent further damage to the vehicle.
