Power Window Control System (Diagnostics - Introduction): Other Toyota Prius C I facelift

PRECAUTION [12/2013 - ]

1. PRECAUTION FOR DISCONNECTING CABLE FROM NEGATIVE AUXILIARY BATTERY TERMINAL NOTE: When disconnecting the cable from the negative (-) auxiliary battery terminal, initialize the following system after the cable is reconnected. System Name See Procedure Power Door Lock Control System Refer to «INITIALIZATION [12/2013 - ]»(ref-651169-S40634195862014081900000)
2. IGNITION SWITCH EXPRESSIONS The type of ignition switch used on this model differs depending on the specifications of the vehicle. The expressions listed in the table below are used in this article. Expression Ignition Switch (Position) Power Switch (Condition) Ignition Switch off LOCK Off (Lock) Ignition Switch ACC ACC On (ACC) Ignition Switch ON (IG) ON (IG) On (IG) Ignition switch ON (READY) ON (READY) On (Ready)
3. POWER WINDOW CONTROL SYSTEM PRECAUTIONS WARNING: The power window control system uses the LIN communication system. Inspect the communication function by following How to Proceed with Troubleshooting. Refer to «HOW TO PROCEED WITH TROUBLESHOOTING [12/2013 - ]»(ref-651382-S36827887332014081900000) . Troubleshoot the power window control system after confirming that the communication system is functioning properly. 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. 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. 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 operations at least 5 times: Close the power window by fully pulling up the power window regulator master switch assembly and holding it in the auto up position. Open the power window by fully pushing down the power window regulator master switch assembly. 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 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. NOTE: Do not disconnect the auxiliary battery while the ignition switch is ON (IG). Otherwise, DTC B2313 will be stored.

INITIALIZATION [12/2013 - ]

1. INITIALIZE POWER WINDOW CONTROL SYSTEM (FOR DRIVER DOOR) 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 (for driver door) is replaced, DTC B2313 is stored. Clear the DTC after initialization. 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 [12/2013 - ]»(ref-651382-S36827887332014081900000) . 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 (IG) or off during initialization. HINT: When the auxiliary 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 auxiliary battery and turn the ignition switch to ON (IG) (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 auxiliary battery and turn the ignition switch to ON (IG). 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 auxiliary battery and turn the ignition switch to ON (IG). 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.
