Principles of Operation

LH Window Operation

The LH window control switch may be used to raise or lower all windows, or each individual side window may be controlled by the control switch located on each door panel.

The one-touch down feature will completely lower the LH window when the LH window control switch is pressed to the second detent and released. The one-touch down feature electronics are integral to the LH window control switch.

Delayed Accessory Power

The Smart Junction Box (SJB) controls power to the power windows with the accessory delay relay. Refer to the Wiring Diagrams for additional vehicle features powered by the accessory delay relay. The SJB activates the accessory delay relay whenever the ignition switch is in the RUN or the ACCESSORY position, or when the ignition switch is changed from RUN or ACCESSORY to the OFF/LOCK position and the LH and RH front doors are closed. Diagrams By Number

The SJB will deactivate the accessory delay relay when:

- the LF door is ajar and the ignition switch is in the OFF/LOCK or KEY-OUT position.
- the RF door is ajar and the ignition switch is in the OFF/LOCK or KEY-OUT position.
- ten minutes have elapsed since the ignition switch was changed from ACC or RUN to the OFF/LOCK position.

Feature inputs:
- LF door ajar switch (open circuit with door closed, grounded with door ajar)
- RF door ajar switch (open circuit with door closed, grounded with door ajar)
- Ignition switch RUN position (battery potential on both the RUN and RUN/ACC inputs)
- Ignition switch ACC position (battery potential on the RUN/ACC input)
- Ignition switch OFF/LOCK position (absence of battery potential on the RUN, RUN/ACC and START inputs)

Feature outputs:
- Accessory delay relay (control circuit grounded when activated, open circuit when deactivated)
