POWER WINDOW CONTROL SYSTEM, Diagnostic DTC:B2313

DTC Code	DTC Name
B2313	Glass Position Initialization Incomplete

DESCRIPTION

The power window regulator motor assemblies are operated by the power window regulator master switch assembly, power window regulator switch assembly or rear power window regulator switch assemblies. The power window regulator motor assembly has motor, regulator and ECU functions.

When the ECU determines that the power window regulator motor assembly has not been initialized, DTC B2313 is stored.
