CUSTOMIZE PARAMETERS

1. CUSTOMIZING FUNCTION WITH TECHSTREAM (REFERENCE) HINT: The following items can be customized. NOTE: When the customer requests a change in a function, first make sure that the function can be customized. Be sure to make a note of the current settings before customizing. When troubleshooting a function, first make sure that the function is set to the default setting. Connect Techstream to the DLC3. Turn the engine switch on (IG). Turn the tester on. Enter the following menus: Customize Setting / Power Window Select the setting by referring to the table below. Power Window (Main Body ECU): CUSTOMIZE PARAMETERS TABLE Tester Display Default Contents Setting Door Key PAW Up ON Function that raises all power windows when, with engine switch off, key is used to hold driver door key cylinder to lock position for more than 2.3 seconds ON/OFF Door Key PA/V Down ON Function that lowers all power windows when, with engine switch off, key is used to hold driver door key cylinder to unlock position for more than 2.3 seconds ON/OFF P/W Down W/ Transmit ON Function that lowers all power windows when, with engine switch off, unlock switch on transmitter is pressed and held for more than 3.0 seconds ON/OFF

1. INITIALIZE POWER WINDOW CONTROL SYSTEM (POWER WINDOW REGULATOR MOTOR ASSEMBLY (ON DRIVER SIDE)) NOTE: DTC B2313 will be set if the driver side power window regulator motor assembly is replaced with a new assembly. Clear the DTC after initializing the power window motor. Initialization should be made when the vehicle is stationary. Be sure to initialize the door glass position memory (pulse sensor) after replacing the driver side power window regulator motor assembly. Without the initialization, the driver door auto up-and-down function, jam protection function and key-off operation will not work. Be sure not to tap or give any shock or force to the door glasses during the initialization procedure as the vehicle is learning the door glasses' sliding resistance during initialization. After replacing the driver side power window regulator, door glass, or glass adhesive dams, be sure to initialize the door glass position memory (pulse sensor). Otherwise, the jam protection function may work when unnecessary. If the initialization procedure cannot be completed normally, there may be a malfunction in the Local Interconnect Network (LIN) communication. Check the body multiplex (LIN, Local Interconnect Network) communication system. Inspection procedure HINT: *1: Even if the door glass has been fully opened before procedure No. 3, it is necessary to press the power window switch down for at least 1 second. *2: As soon as the switch is pulled completely up (Automatic Closing), the master switch indicator starts to blink. *3: If the master switch indicator does not come on after procedure No. 4, restart from procedure No. 3. *4: Allow the automatic operation to continue without stopping until the door glass is fully closed. Check the body multiplex (LIN, Local Interconnect Network) system (See «SYSTEM DESCRIPTION»(ref-290710-S21375411672008071700000) ).
2. TO RETURN THE SYSTEM TO THE PRE-INITIALIZED CONDITION NOTE: After replacing or reinstalling the driver side power window regulator, door glass, or door glass adhesive dams, be sure to initialize the door glass position memory (pulse sensor). Otherwise, the jam protection function may work when unnecessary. Procedure HINT: *1: Even if the door glass has been fully closed before procedure No. 3, it is necessary to pull the power window switch up for at least 6 seconds while the door glass is fully closed. *2: After completing procedure No. 4, return the door glass switch to its neutral position, then perform automatic opening operation. *3: After completing the whole initialization process, make sure that the door glass fully closes with the automatic closing operation. If the initialization procedure cannot be completed normally, there may be a malfunction in the Local Interconnect Network (LIN) communication. Check the body multiplex (LIN, Local Interconnect Network) communication system (See «SYSTEM DESCRIPTION»(ref-290710-S21375411672008071700000) ).

1. DESCRIPTION The power window control system data can be read from the Data Link Connector 3 (DLC3) of the vehicle. When the system seems to be malfunctioning, use Techstream to check for malfunctions and perform repairs.
2. CHECK DLC3 Check the DLC3 (See «HOW TO TROUBLESHOOT ECU CONTROLLED SYSTEMS»(ref-290683-S36107070032008071700000) ).
3. INSPECT BATTERY VOLTAGE Measure the battery voltage. Standard voltage: 11 to 14 V If the voltage is below 11 V, recharge or replace the battery before proceeding to the next step.
4. CHECK DIAGNOSIS HINT: If there is a malfunction in the pulse sensor, manually operating the power window switch will cause the power window switch light to blink. Turn the ignition switch on (IG). Manually operate the power window master switch or power window switch on each door. Check the blinking pattern of the AUTO light as shown below. If pattern (A) is displayed, check the wire harness or power window ECU. If pattern (B) is displayed, check the power window regulator motor or power window ECU. If the normal pattern is displayed, replace the power window regulator master switch.
