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.

CAUTION / NOTICE / HINT

Note

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.

Click here
Inspect the fuses for circuits related to this system before performing the following procedure.
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.
