DESCRIPTION
The power window regulator motor assemblies are operated by the power window regulator master switch assembly, front power window regulator switch assembly RH. The power window regulator motor assemblies have motor, regulator and ECU functions.
This DTC is output when the power window regulator motor assembly has a malfunction, or the ECU built into the regulator motor assembly determines that the fully closed window position has deviated approximately 20 mm (0.787 in.) or more from the normal position.
HINT:
DTC B2311 can be stored in each power window regulator motor assembly (power window ECU).
