Acura Electrical System Service Requirements Part Il Honda Motor Co., Ltd. Power Windows Description The power windows can still be operated for about 10 minutes after the ignition switch is turned from the “II” to the “I” or “O” position as long as neither of the doors has been opened. This provides a convenience to parked occupants while offering a degree of security against unwanted or accidental window operation. Circuit Diagram (See page 16) Several different wires have the same color. They have been given a number suffix to distinguish them (for example YEL 1| and YEL 2 are not the same). “DN” in the switch circuit denotes DOWN. Control Unit Input Test The control unit only controls the driver’s door window. Remove the driver’s door trim panel and disconnect the 4-P and 6-P connec- tors from the control unit. Make the fol- lowing input tests at the harness pins. To test the unit, keep the driver’s switch connector connected with the door wire harness. Recheck the con- nections between the 4-P and 6-P con- Component Location Index R, REAR MOTOR POWER WINDOW RELAY UNDER-HOOD RELAY BOX RELAY BRACKET (Located under dash, left side) POWER WINDOW CONTROL UNIT KEY-OFF TIMER CIRCUIT (in the integrated control unit) R.
