PRECAUTION [05/2013 - ]

1. IGNITION SWITCH EXPRESSION HINT: The type of ignition switch used on this model differs according to the specifications of the vehicle. The expressions listed in the table below are used in this Service Information. Expression Ignition Switch (Position) Engine Switch (Condition) Ignition Switch off LOCK Off (Lock) Ignition Switch ON ON On (IG) Ignition Switch ACC ACC On (ACC) Engine Start START On (Start)
2. POWER WINDOW CONTROL SYSTEM PRECAUTIONS (FOR DRIVER SIDE) WARNING: 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 trouble codes are output. If any of the following parts is removed or replaced, initialization must be performed. Door belt moulding Door lower frame Door trim board Window regulator Door panel Door glass run Door glass After any 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 operation at least 5 times: Close the power window by fully pulling up the power window switch and holding it at the auto up position. Open the power window by fully pushing down the power window switch. The jam protection function may operate unexpectedly even when the power window control system is normal, due to detection of a value different from 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 driving on a rough road. A power window is being opened or closed while the door is being opened or closed. A sharp voltage change. NOTE: Do not disconnect the cable from the negative (-) battery terminal while the ignition switch is ON. Otherwise, DTC B2313 will be stored.

INITIALIZATION [05/2013 - 01/2014]

1. INITIALIZE POWER WINDOW CONTROL SYSTEM (POWER WINDOW REGULATOR MOTOR ASSEMBLY [FOR DRIVER SIDE]) WARNING: If any of the following parts is removed or replaced, initialization must be performed. Door belt moulding Door lower frame Door trim board Window regulator Door panel Door glass run Door glass Functions such as auto up/down, jam protection remote control do not operate if the initialization is not performed. 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, jam protection and key-off operation will not operate if initialization is not performed. When a power window regulator motor assembly LH is replaced, DTC B2313 is stored. When performing initialization, do not perform any other procedures. If initialization is not completed properly, the LIN communication system may be malfunctioning. Refer to «HOW TO PROCEED WITH TROUBLESHOOTING [05/2013 - 01/2014]»(ref-615309-S21837371712014050900000) . Make sure to park the vehicle and turn off all the 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 ignition switch to ON or off during initialization. HINT: When the battery is 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 the power window regulator motor assembly has been 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 ignition switch to ON (at this time, the LED on the power window regulator master switch assembly blinks to indicate that it is ready for initialization). Fully open the window by fully pushing down the power window regulator master 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 power window regulator master switch assembly, and hold the switch for 1 second or more after the window is fully closed to reset the glass position. The LED on the power window regulator master switch assembly stops blinking and illuminates to indicate that initialization is complete. Procedure B Connect the battery and turn the ignition switch to ON. Fully close the power window by fully pulling up the power window regulator master 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 again). Fully open the window by pushing down the power window regulator master switch assembly, and hold the switch for 1 second or more after the window is fully opened. Release the power window regulator master 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 power window regulator master switch assembly, and hold the switch for 1 second or more after the window is fully closed to reset the glass position and complete initialization. Procedure C Connect the battery and turn the ignition switch to ON. Fully open the window by fully pushing down the power window regulator master 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 power window regulator master switch assembly, and hold the switch for 1 second or more after the window is fully closed to reset the glass position and complete initialization.
