LIN COMMUNICATION SYSTEM, Diagnostic DTC:B2325

DTC Code DTC Name
B2325 LIN Communication Bus Malfunction

DESCRIPTION

The main body ECU (multiplex network body ECU) intermittently monitors the LIN communication bus between the components related to the doors. DTC B2325 is stored when a malfunction in the LIN communication bus between the components related to the doors is detected consecutively 3 times.

DTC No. Detection Item DTC Detection Condition Trouble Area
B2325 LIN Communication Bus Malfunction Main body ECU (multiplex network body ECU) detects errors in communication with the ECUs connected to the door bus lines 3 times in a row.

  • Main body ECU (multiplex network body ECU)

  • Driver side junction block assembly

  • Front multiplex network door ECU LH

  • Front multiplex network door ECU RH

  • Multiplex network master switch assembly

CAUTION / NOTICE / HINT

Note


  • When using the GTS with the engine switch off to troubleshoot:

    Connect the GTS to the vehicle and turn a courtesy light switch on and off at 1.5 second intervals until communication between the GTS and vehicle begins.

  • When the power window regulator motor assembly (driver side) is removed and reinstalled or replaced, the power window regulator motor assembly (driver side) must be initialized.

  • Recognition code registration is necessary when replacing the main body ECU (multiplex network body ECU).

  • If the main body ECU (multiplex network body ECU) is replaced, refer to the Service Bulletin.

Tech Tips

When DTC B2325 and a LIN communication stop DTC are output simultaneously, first perform troubleshooting for DTC B2325. Then perform troubleshooting for the LIN communication stop DTC.
