POWER WINDOW SYSTEM
PRECAUTIONS
1. Precautions for Power window system
CAUTION:
·Power window system uses large-scale multiplex communication for vehicle body [LIN]. At first, follow the “How to proceed the troubleshooting” and perform the “Communication function checking” to check that malfunction does not occur in the communication system, and then proceed to the troubleshooting.
·When malfunction occurs in the auto-reverse function of the power window system, disable the AUTO operation. Otherwise, accidental pinching may arise. Check that the diagnostic code is not output, then proceed to the troubleshooting.
·When replacing the power window regulator motor ASSY with a new one or reusing its motor, perform the initialization of the power window system. (Refer to )
·After replacing door glass and/or weather strip, AUTO UP operation sometimes activates auto-reverse function. In this case, the door glass is fully closed by performing the procedure in the following order (*3). AUTO U0 HOLD → (the auto-reverse function (glass reverse operation)) → (*1) → AUTO U0 HOLD → (the auto-reverse function (glass reverse operation)) → AUTO UP HOLD (*2).
·*1: If DOWN operation, IG OFF & timer operation OFF, and/or index operation is executed between auto-reverse function and AUTO UP HOLD, return to the beginning of the procedure.
·*2: The upper end position of the glass is relearned by this operation (AUTO UP HOLD). (Refer to )
·*3: The failure of the door glass or regulator may prevent full closing of the door glass.
·Even if the power window system is normal, unexpected operation of the auto-reverse function may occur resulting from the abrupt change of the opening/closing speed of the window. This symptom occurs when the system detects any value out of the learned operation.
·Window opening/closing operation while driving the vehicle on rough roads.
·Window opened/closed operation when door is opened/closed.
·Sudden voltage variation occurs.
·Never disconnect the battery with IG ON. If the battery is disconnected while IG ON, DTC may not be output properly.

REGISTRATION SETTINGS
1. Initialization of power window regulator motor
CAUTION:
·When replacing the power window regulator motor ASSY with a new one or reusing its motor, the power window regulator motor must be initialized. If the initialization is not performed, AUTO operation, auto-reverse function, and after-key-OFF operation function does not work properly.
·If the power window regulator motor ASSY is replaced with a new one, DTC B2313 and B2316 are output. After initializing power window (initialization of pulse sensor), erase the diagnostic codes.
·After replacing the glass and/or weather strip, an AUTO UP operation on the worked glass (door glass) sometimes causes detection of value out of learned operation, then activates auto-reverse function. In this case, the door glass is fully closed by performing the procedure in the following order (*3). AUTO U0 HOLD → (the auto-reverse function (glass reverse operation)) → (*1) → AUTO U0 HOLD → (the auto-reverse function (glass reverse operation)) → AUTO UP HOLD (*2).
·*1: If DOWN operation, IG OFF & timer operation OFF, and/or index operation is executed between auto-reverse function and AUTO UP HOLD, return to the beginning of the procedure.
·*2: The upper end position of the glass is relearned by this operation (AUTO UP HOLD). (Refer to )
·*3: The failure of the door glass or regulator may prevent full closing of the door glass.
·If the initialization cannot be completed normally, check the large-scale multiplex communication system for vehicle body [LIN]. (Refer to )
NOTE:
After battery replacement, no initialization for power window regulator motor is needed because the nonvolatile memory stores the necessary information.
(1) Initial setting method
(a) Close the door and turn the ignition switch to ON.
(b) As shown in the figure, move the door glass to middle position.
(c) Operate power window regulator switch (AUTO UP HOLD) and close the door glass completely, and continue the switch operation for 1 second or more. This will reset the position of the door glass, and the initialization is completed.
NOTE:
·The initialization of the passenger's seat is performed with the passenger's side switch.
·Before completion of the initialization, the window of the passenger's seat is not operable through the power window regulator master switch ASSY.
·Until the initialization is complete, AUTO UP, DOWN or reverse operation is disabled.
