LIN COMMUNICATION SYSTEM, Diagnostic DTC:B2325

DTC Code DTC Name
B2325 LIN Communication Bus Malfunction

DESCRIPTION

The main body ECU (multiplex network body ECU) monitors communication between all the ECUs connected to the door bus lines. When the main body ECU (multiplex network body ECU) detects errors in communication with all the ECUs connected to the door bus lines at 2.6-second intervals and 3 times in a row, DTC B2325 will be stored.
