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 and sliding roof drive gear sub-assembly. DTC B2325 is stored when a malfunction in the LIN communication bus between the components related to the doors and sliding roof drive gear sub-assembly 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.

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 seconds intervals until communication between the GTS and vehicle begins.

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