POWER WINDOW CONTROL SYSTEM, Diagnostic DTC:B2313

DTC Code DTC Name
B2313 Glass Position Initialization Incomplete

DESCRIPTION

The portion of the power window control system that is located in the driver door consists of a power window master switch, regulator, and a motor with an integrated ECU. The driver door power window regulator motor is controlled by the ECU when the power window master switch is operated (models with jam protection).

When the ECU determines that the driver's door power window regulator motor assembly has not been initialized, DTC B2313 is set.

Note

The power window control system uses a serial communication protocol (LIN) to communicate with the main body ECU. 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.

Tech Tips


  • Replacing the door glass or door glass run may cause a difference to exist between the current door glass position and the position memorized in the ECU. In this case, the jam protection function may work improperly. Return the system to the pre-initialized condition and reinitialize the system.
