WINDSHIELD / WINDOWGLASS: POWER WINDOW CONTROL SYSTEM: B2313: Glass Position Initialization Incomplete
B2313 - Glass Position Initialization Incomplete

DESCRIPTION

The driver door power window regulator motor is driven by operating the power window regulator master switch. The driver door power window regulator motor has motor, regulator, and ECU functions.

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

NOTICE:
* The power window control system uses a multiplex communication system (LIN). 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.
* When the power window regulator motor assembly (on the driver side) is reinstalled or replaced, the power window control system must be initialized.
* After a door glass or a door glass run has been replaced, the jam protection function may operate unexpectedly when the AUTO UP function is used. In such cases, the AUTO UP function can be resumed by repeating the following operation at least 5 times:
(1) Close the power window by fully pulling up the power window switch and holding it in the AUTO UP position.
(2) Open the power window by fully pushing down the switch.
