SYSTEM NAME REFERENCE CHART System Name See procedure Navigation System (for DVD) «INITIALIZATION»(ref-349706-S07943075812009120800000) Advanced Parking Guidance System Power Trunk Lid System Rear Door Sunshade System
2. PRECAUTIONS WHEN USING TECHSTREAM When using the Techstream with the engine switch off to troubleshoot: Connect the Techstream to the vehicle, and turn a courtesy light switch on and off at 1.5 second intervals until communication between the Techstream and vehicle begins. After all DTCs are cleared, check if the trouble occurs again 6 seconds after the engine switch on (IG).
3. POWER WINDOW CONTROL SYSTEM PRECAUTIONS CAUTION: 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 power window regulator or the power window regulator motor assembly is 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 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 different operation learned value when the door glass moving speed changes sharply under any of the following conditions: A power window being opened or closed while the vehicle is driving on a rough road. A power window being opened or closed while the door is being opened or closed. A sharp voltage change. NOTE: Do not disconnect the battery while the engine switch is on (IG). Otherwise, DTC B2311 will be output.

INITIALIZATION

1. INITIALIZE POWER WINDOW CONTROL SYSTEM (POWER WINDOW REGULATOR MOTOR ASSEMBLY (ALL DOORS)) CAUTION: When the power window regulator motor assembly is reinstalled or replaced, the power window control system must be initialized. Functions such as the AUTO UP/DOWN, jam protection and key-off do not operate if the initialization is not performed. HINT: When the battery is replaced, it is not necessary to initialize the power window regulator motor. NOTE: When the power window regulator motor assembly is replaced, DTC B2313 is output. Clear the DTC after the initialization. When performing initialization, do not perform any other procedures. 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, due to detection of the different operation learned value of the door glass movement speed. In such cases, the AUTO UP function can be resumed by repeating the following operation at least 5 times: Open the power window by fully pushing down the switch. Close the power window by fully pulling up the power window switch and holding it at the AUTO UP position. If the initialization is not completed properly, the LIN communication system may have a malfunction (see «HOW TO PROCEED WITH TROUBLESHOOTING»(ref-349747-S33852239962009120800000) ).
