Circuit description
Operating the power window regulator master switch ASSY and the power window regulator switch ASSY drives the power window regulator motor ASSY LH (driver's seat) and power window regulator motor ASSY RH (passenger's seat). The power window regulator motor ASSY LH (driver's seat) and power window regulator motor ASSY RH (passenger's seat) have motor function and regulator function.
B2312 and B2315 is generated when ECM determines that the power window regulator master switch ASSY or power window regulator switch ASSY is stuck continuously.
- 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 REGISTRATION SETTINGS )
- 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 UP HOLD →(the auto-reverse function (glass reverse operation)) →(*1)→AUTO UP 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 REGISTRATION SETTINGS )
*3: The failure of the door glass or regulator may prevent full closing of the door glass.
