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.
- *: w/ Sliding Roof System

 CAUTION / NOTICE / HINT
NOTICE:
- When using the Techstream with the engine switch off to troubleshoot:
Connect the Techstream to the vehicle and turn a
courtesy light switch on and off at 1.5 second intervals until
communication between the Techstream 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.

- w/ Sliding Roof System:
When the sliding roof drive gear sub-assembly is
removed and reinstalled or replaced, the sliding roof drive gear
sub-assembly must be initialized.

HINT: 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. PROCEDURE
