DTC Code DTC Name
B2311 Power Window Motor Malfunction

DESCRIPTION

The power window regulator motor assemblies are operated by the power window regulator master switch assembly or power window regulator switch assembly. 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.

INSPECTION PROCEDURE

Note


  • DTC B2311 is stored in each power window regulator motor assembly.

  • If the power window regulator motor assembly (for driver door) or power window regulator motor assembly (for front passenger door) has been replaced with a new one, initialize the power window control system Click here.

  • If the power window regulator motor assembly (for driver door) or power window regulator motor assembly (for front passenger door) and door window regulator sub-assembly have been removed and installed, or if the power window regulator motor assembly (for driver door) or power window regulator motor assembly (for front passenger door) 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 inspection 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 Click here.
