Driver's Door Glass AUTO UP/DOWN Function Does Not Work (Manual Operation Works)

Circuit description

If AUTO does not function, the fail safe may be working. Or, not performing the initialization of the power window regulator master switch ASSY RH (driver's seat) after repair also disables AUTO.

CAUTION:
- When replacing the power window regulator motor ASSY with new one or reusing its motor, perform the initialization of the power window system.
- 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).
- *3: The failure of the door glass or regulator may prevent full closing of the door glass.

NOTE: If any malfunction occurs on the pulse sensor in the power window regulator motor ASSY RH (driver's seat), the fail safe function is triggered. When fail safe is active, remote operation from the passenger's seat and AUTO operation are disabled. (During AUTO UP HOLD operation, only manual UP and manual DOWN operations are possible).
