WARNING: This page is about a different car, the 2006 Mercury Milan, 2006 Lincoln Zephyr, and 2006 Ford Fusion. However, it is still accessible from the selected car via links, so may be relevant.
Battery junction box (BJB) fuse 44 (15A) supplies fused battery voltage to the brake on/off (BOO) switch, along circuit CBP44 (VT), with the ignition switch in the RUN/START position. With the brake pedal released, the BOO switch is closed and voltage is supplied to the ABS module from the switch along circuit CES09 (VT/OG). When the brake pedal is applied, the BOO switch opens and the voltage supply is interrupted.
