POWER WINDOW CONTROL SYSTEM (for Models with Jam Protection Function on 4 Windows) > Rear Power Window RH does not Operate with Rear Power Window Switch RH

​

DESCRIPTION

HINT:

If the pulse sensor built into the power window regulator motor (for rear RH 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 RH side) at the auto up position, and opened manually by pushing down the power window regulator switch assembly (for rear RH side).

INSPECTION PROCEDURE

NOTICE:

1. The power window control system uses a multiplex communication system (LIN communication system). Inspect the communication function by following How to Proceed with Troubleshooting (Click here). Troubleshoot the power window control system after confirming that the communication system is functioning properly.
   
2. When the power window regulator motor assembly (for rear RH side) is reinstalled or replaced, the power window control system must be initialized.
   
3. 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:
   
4. 1. Close the power window by fully pulling up the power window regulator switch assembly (for rear RH 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 RH side).
      
5. When the ECU determines that the power window regulator motor assembly (for rear RH side) has a malfunction, DTC B2311 is set.
   

1. Connect the intelligent tester to the DLC3.

2. Turn the ignition switch to ON.

3. Turn the intelligent tester on.
