Rear Power Window LH Does Not Operate With Rear Power Window Switch LH

WINDOW / GLASS: POWER WINDOW CONTROL SYSTEM: Rear Power Window LH does not Operate with Rear Power Window Switch LH
- Rear Power Window LH does not Operate with Rear Power Window Switch LH

DESCRIPTION

When the engine is running or the ignition switch is ON, the power window regulator motor assembly (for rear LH side) is operated by the power window regulator switch assembly (for rear LH side). The power window regulator motor has motor, regulator, and ECU functions.

HINT
If the pulse sensor built into the power window regulator motor assembly (for rear LH side) malfunctions, the power window control system enters fail-safe mode. The remote up/down and auto up/down functions cannot be operated during fail-safe mode. However, the power window can be closed by holding the power window regulator switch assembly (for rear LH side) at the auto up position, and opened manually by pushing down the power window regulator switch assembly (for rear LH side).

INSPECTION PROCEDURE

NOTICE:
* The power window control system uses a multiplex communication system (LIN communication system). Inspect the communication function by following How to Proceed with Troubleshooting 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 (for rear LH 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 reinitialized by repeating the following operations at least 5 times:
(1) Close the power window by fully pulling up the power window regulator switch assembly (for rear LH side) and holding it at the auto up position.
(2) Open the power window by fully pushing down the power window regulator switch assembly (for rear LH side).
* When the ECU determines that the power window regulator motor assembly (for rear LH side) has a malfunction, DTC B2311 is set.
