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 a power window regulator motor assembly is
malfunctioning, or the ECU built into the power window regulator motor
assembly determines that the fully closed power window position has
deviated approximately 20 mm (0.787 in.) or more from the normal
position. D-Door Motor |

 CAUTION / NOTICE / HINT
NOTICE:
- DTC B2311 is stored 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.
Click here 
- If a power window regulator motor assembly and door window regulator
sub-assembly have been removed and installed, or if a power window
regulator motor assembly was reused when a door glass or door glass run
was replaced, initialize the power window control system.
