DTC |
B2311 |
Power Window Motor Malfunction |
DESCRIPTION
The power window regulator motor assemblies are operated by the multiplex network master switch assembly, front power window regulator switch assembly RH or rear power window regulator switch assemblies. 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).

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 (See page
![2016 - 2020 MY Sienna [12/2015 - ]; WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: INITIALIZATION](/t3Portal/stylegraphics/info.gif)
).
-
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 (See page
).
-
The power window control system uses the LIN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Troubleshoot the power window control system after confirming that the communication system is functioning properly (See page
).
