WINDOW / GLASS  POWER WINDOW CONTROL SYSTEM(for NR Series Engine)  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. Each 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.

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.
