WINDOW / GLASS POWER WINDOW CONTROL SYSTEM B2312 Power Window Switch Malfunction
DESCRIPTION
The power window regulator motor assemblies are operated by the multiplex network master switch assembly, power window regulator switch assembly or rear power window regulator switch assemblies. The power window regulator motor assemblies have motor, regulator and ECU functions.
This DTC is stored when the ECU built into a power window regulator motor assembly and multiplex network master switch assembly determine that the multiplex network master switch assembly, power window regulator switch assembly or rear power window regulator switch assembly is stuck.

WIRING DIAGRAM
CAUTION / NOTICE / HINT
- NOTICE:
- ·
DTC B2312 is stored in the multiplex network master switch assembly and in each power window regulator motor assembly.
·If a power window regulator motor assembly has been replaced with a new one, initialize the power window control system.
·Inspect the fuses for circuits related to this system before performing the following procedure.
·The power window control system uses the LIN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the power window control system after confirming that the communication system is functioning properly.
- HINT:
-
If DTC B2312 is not output again after the DTC has been cleared, the DTC was stored due to the switch being held in the same position continuously.
