      Refer to HOW TO PROCEED WITH TROUBLESHOOTING [08/2013 - 08/2016]

    • The power window control system prohibits the auto up and down function when the jam protection function malfunctions.
    • If the power window regulator motor assembly (for driver door) has been replaced with a new one, initialize the power window control system.
    • If the power window regulator motor assembly (for driver door) and door window regulator sub-assembly have been removed and installed, or if the power window regulator motor assembly (for driver door) was reused when the door glass or door glass run was replaced, initialize the power window control system.
    • The jam protection function may operate unexpectedly, even when the power window control system is normal, due to detection of a value different than the operation learned value when the door glass moving speed changes sharply under any of the following conditions:
      1. A power window is being opened or closed while the vehicle is driven on a rough road.
      2. A power window is being opened or closed while the door is being opened or closed.
      3. The voltage changes abruptly.
    • Do not disconnect the battery while the ignition switch is ON. Otherwise, DTC B2313 will be stored.
