| DTC Code | DTC Name |
|---|---|
| B2325 | LIN Communication Bus Malfunction |
DESCRIPTION
If the main body ECU (multiplex network body ECU) detects a communication error with an ECU connected to the door bus lines for 7 seconds or more, DTC B2325 will be stored.
| DTC No. | Detection Item | DTC Detection Condition | Trouble Area |
|---|---|---|---|
| B2325 | LIN Communication Bus Malfunction | The main body ECU (multiplex network body ECU) detects a communication error with an ECU connected to the door bus lines for 7 seconds or more. |

*1: w/ Sliding Roof System
*2: w/ Double Locking System
WIRING DIAGRAM
CAUTION / NOTICE / HINT
Note
Inspect the fuses for circuits related to this system before performing the following procedure.
When a power window regulator motor assembly is replaced or removed and reinstalled, it is necessary to perform initialization.
When the sliding roof ECU (sliding roof drive gear sub-assembly) is replaced or removed and reinstalled, it is necessary to perform initialization. (w/ Sliding Roof System)
Before performing the inspection, check that DTC B1206, B1249, B1273, B2321, B2322, B2323 or B2324 is not output.
If the main body ECU (multiplex network body ECU) is replaced, refer to Service Bulletin.
