Flow INFOID:0000000001702334 DETAILED FLOW 1. OBTAIN INFORMATION ABOUT SYMPTOM Interview the customer to obtain the malfunction information (conditions and environment when the malfunc- tion occurred) as much as possible when the customer brings the vehicle in. >> GO TO 2 2. REPRODUCE THE MALFUNCTION INFORMATION Check the malfunction on the vehicle that the customer describes. Inspect the relation of the symptoms and the condition when the symptoms occur. >> GO TO 3 3. IDENTIFY THE MALFUNCTIONING SYSTEM WITH “SYMPTOM DIAGNOSIS” Use “Symptom diagnosis” from the symptom inspection result in step 2 and then identify where to start per- forming the diagnosis based on possible causes and symptoms. >> GO TO 4 4. IDENTIFY THE MALFUNCTIONING PARTS WITH “COMPONENT DIAGNOSIS” Perform the diagnosis with “Component diagnosis” of the applicable system. >> GO TO 5 5. REPAIR OR REPLACE THE MALFUNCTIONING PARTS Repair or replace the specified malfunctioning parts. >> GO TO 6 6. FINAL CHECK Check that malfunctions are not reproduced when obtaining the malfunction information from the customer, referring to the symptom inspection result in step 2. Are the malfunctions corrected? YES >> INSPECTION END NO >> GO TO 3POWER WINDOW SYSTEM PWC-5C D E F G H I J L M A B PWC N O P FUNCTION DIAGNOSIS POWER WINDOW SYSTEM System Diagram INFOID:0000000001702335 FRONT WINDOW ANTI-PINCH SYSTEM System Description INFOID:0000000001702336 POWER WINDOW MAIN SWITCH INPUT/OUTPUT SIGNAL CHART POWER WINDOW AND DOOR LOCK/UNLOCK SWITCH INPUT/OUTPUT SIGNAL CHART ALCIA0038GB Item Input signal to main power window and door lock/unlock switch Main power window and door lock/unlock switch function Actuator Key cylinder switch LOCK/UNLOCK signal (more than 1.5 seconds over) Power window control Front power window motor Encoder Encoder pulse signal Main power window and door lock/unlock switch Front power window motor LH UP/ DOWN signal Power window and door lock/unlock switch RH Front power window motor RH UP/ DOWN signal BCM RAP signal Rear power window switch Rear power window motor UP/DOWN signal Rear power window motorPWC-6POWER WINDOW SYSTEM POWER WINDOW OPERATION  Power window system is operable during the retained power operation timer after turning ignition switch ON and OFF.  Main power window and door lock/unlock switch can open/close all windows.  Power window and door lock unlock switch RH & rear power window switches LH and RH can open/close the corresponding windows. POWER WINDOW AUTO-OPERATION (FRONT LH & RH)  AUTO UP/DOWN operation can be performed when main power window and door lock/unlock switch & power window and door lock/unlock switch RH turns to AUTO.  Encoder continues detecting the movement of power window motor and transmits to power window switch as the encoder pulse signal while power window motor is operating.  Power window switch reads the changes of encoder signal and stops AUTO operation when door glass is at fully opened/closed position.  Power window motor is operable in case encoder is malfunctioning. RETAINED POWER OPERATION  Retained power operation is an additional power supply function that enables power window system to oper- ate during the 45 seconds even when ignition switch is turned OFF Retained power function cancel conditions  Front door CLOSE (door switch OFF)→OPEN (door switch ON).  When ignition switch is ON.  When timer time passes. (45 seconds) POWER WINDOW LOCK Ground circuit inside main power window and door lock/unlock switch shuts off when power window lock switch is ON. This inhibits power window switch operation except with the main power window and door lock/ unlock switch. ANTI-PINCH OPERATION (FRONT LH & RH)  Pinch foreign material in the door glass during AUTO-UP operation, and it is the anti-pinch function that low- ers the door glass 150 mm (5.91 in) or 2 seconds when detected.  Encoder continues detecting the movement of power window motor and transmits to power window switch as the encoder pulse signal while power window motor is operating.  Resistance is applied to the power window motor rotation that changes the frequency of encoder pulse sig- nal if foreign material is trapped in the door glass.  Power window switch controls to lower the window glass for 150 mm (5.91 in) or 2 seconds after it detects encoder pulse signal frequency change. OPERATION CONDITION  When all door glass AUTO-UP operation is performed (anti-pinch function does not operate just before the door glass closes and is fully closed) NOTE: Depending on environment and driving conditions, if a similar impact or load is applied to the door glass, it may lower. KEY CYLINDER SWITCH OPERATION Hold the door key cylinder to the LOCK or UNLOCK direction for more than 1 second to OPEN or CLOSE front power windows when ignition switch is OFF. In addition, it stops when key position is moved to NEUTRAL when operating. OPERATION CONDITION  Ignition switch OFF Item Input signal to front power window switch Front power window switch function Actuator Power window and door lock/unlock switch RH Front power window motor RH UP/ DOWN signal Power window
