  2. POWER WINDOW CONTROL SYSTEM PRECAUTIONS

    Note


    • The power window control system uses a 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.

    • The power window control system prohibits the AUTO UP/DOWN function when the jam protection function malfunctions. Therefore, troubleshoot the power window control system after confirming that no diagnostic codes are displayed.

    • When the front door window regulator assembly (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 operations at least 5 times:


      1. Close the power window by fully pulling up the power window regulator master switch assembly and holding it in the auto up position.

      2. Open the power window by fully pushing down the power window regulator master switch assembly.

    • The jam protection function may operate unexpectedly even when the power window control system is normal, due to detection of a different operation learned value when the door glass moving speed changes sharply under any of the following conditions:


      1. A power window is opened or closed while the vehicle is being driven on a rough road.

      2. A power window is opened or closed while the door is being opened or closed.

      3. A sharp voltage change.

    • Do not disconnect the auxiliary battery while the ignition switch is ON (IG). Otherwise DTC B2313 will be output.
