POWER WINDOW CONTROL SYSTEM, Diagnostic DTC:B2311

DTC Code DTC Name
B2311 Power Window Motor 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 output when a power window regulator motor assembly is malfunctioning, or the ECU built into the power window regulator motor assembly determines that the fully closed window position has deviated approximately 20 mm (0.787 in.) or more from the normal position.
