Passenger Window-Up Input Signal
The body control module (BCM) monitors the state of the Passenger Window UP and Passenger Window DOWN switches at X4-14 and X4-12 respectively. When the Automatic Window DOWN feature is in progress, if the Driver Window UP switch is operated for any length of time, the window stops immediately as the motor is immediately presented with battery voltage across both terminals. The BCM senses this switch voltage on X4-14, and de-energizes the relay to permit the polarity across the motor to change, and for the window to commence winding upwards. NOTE: If the Passenger Window DOWN switch is pressed while Auto Window DOWN feature is in progress, the BCM senses this request at X4-12, but the BCM will not de-energize the relay until the Driver Window DOWN switch is released.
