2. POWER WINDOW CONTROL SYSTEM PRECAUTIONS NOTE: The power window control system uses the LIN communication system. 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. Refer to «HOW TO PROCEED WITH TROUBLESHOOTING [04/2013 - ]»(ref-665547-S10690388912014102400000) 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 has been replaced with a new one, initialize the power window control system. Refer to «INITIALIZATION [04/2013 - ]»(ref-665547-S39448188862014102400000) If the power window regulator motor assembly and door window regulator sub-assembly have been removed and installed, or if the power window regulator motor assembly was reused when a door glass or door glass run was replaced, initialize the power window control system. Refer to «INITIALIZATION [04/2013 - ]»(ref-665547-S39448188862014102400000) 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: A power window is being opened or closed while the vehicle is driven on a rough road. A power window is being opened or closed while the door is being opened or closed. The voltage changes abruptly. Do not disconnect the battery while the engine switch is on (IG). Otherwise, DTC B2313 will be stored. Refer to «DTC B2313: Glass Position Initialization Incomplete [04/2013 - ]»(ref-665860-S04377960542014102400000)

INITIALIZATION [04/2013 - ]

1. INITIALIZE POWER WINDOW CONTROL SYSTEM (ALL DOORS) NOTE: When a door window regulator assembly, power window regulator motor assembly, door glass or door glass run is reinstalled or replaced, the power window control system must be initialized. Functions such as the auto up and down function, jam protection function, remote control function, key-linked function, wireless transmitter-linked function, key-off operation function and window open warning function will not operate if initialization is not performed. When a power window regulator motor assembly is replaced, DTC B2313 is stored. Clear the DTC after initialization. Refer to «DTC CHECK / CLEAR [04/2013 - ]»(ref-665547-S06891713832014102400000) When performing initialization, do not perform any other procedures. When performing initialization, use the power window switch of each door to initialize each door window. If initialization does not complete properly, the LIN communication system may be malfunctioning. Refer to «HOW TO PROCEED WITH TROUBLESHOOTING [04/2013 - ]»(ref-665832-S17970494342014102400000) Make sure to park the vehicle and turn off all electrical systems before performing initialization. Initialization will be canceled if the vehicle is driven during initialization. Make sure not to hit, strike or vibrate the door window glass during initialization because the vehicle is learning the sliding resistance of the door window glass. Make sure not to turn the engine switch on (IG) or off during initialization. HINT: If the battery has been replaced, it is not necessary to initialize the power window regulator motor assembly. Perform initialization according to the table below. Condition of Power Window Proceed to Initialization method when a power window regulator motor assembly has been replaced with a new one. Procedure A Initialization method when a power window regulator motor assembly has been removed/installed or a door glass and/or door glass run etc. have been removed/installed or replaced with new ones. HINT: Use this procedure if a power window regulator motor assembly is being reused. Procedure B Initialization method when a reverse rotation malfunction occurs due to a sliding resistance change resulting from adjustment etc. Procedure C Procedure A Connect the battery and turn the engine switch on (IG). Fully open the power window by fully pushing down the multiplex network master switch assembly, power window regulator switch assembly or rear power window regulator switch assembly, and hold the switch for 1 second or more after the window is fully opened. Fully close the power window by fully pulling up the multiplex network master switch assembly, power window regulator switch assembly or rear power window regulator switch assembly, and hold the switch for 1 second or more after the power window is fully closed to reset the glass position and complete initialization. Procedure B Connect the battery and turn the engine switch on (IG). Fully close the power window by fully pulling up the multiplex network master switch assembly, power window regulator switch assembly or rear power window regulator switch assembly, and hold the switch for 6 seconds or more after the window is fully closed (if the power window does not move or stops halfway, even when the switch is fully pulled up, release the switch and fully pull it up again). Fully open the power window by fully pushing down the multiplex network master switch assembly, power window regulator switch assembly or rear power window regulator switch assembly, and hold the switch for 1 second or more after the power window is fully opened. Release the multiplex network master switch assembly, power window regulator switch assembly or rear power window regulator switch assembly. Then fully push down and hold the switch for 4 seconds or more. Fully close the power window by fully pulling up the multiplex network master switch assembly, power window regulator switch assembly or rear power window regulator switch assembly, and hold the switch for 1 second or more after the power window is fully closed to reset the glass position and complete initialization. Procedure C Connect the battery and turn the engine switch on (IG). Fully open the power window by fully pushing down the multiplex network master switch assembly, power window regulator switch assembly or rear power window regulator switch assembly, and hold the switch for 1 second or more after the power window is fully opened. Fully close the power window by fully pulling up the multiplex network master switch assembly, power window regulator switch assembly or rear power window regulator switch assembly, and hold the switch for 1 second or more after the power window is fully closed to reset the glass position and complete initialization.
