When the brake pedal is pressed, fused battery voltage is sent to the brake on/off (BOO) switch from central junction box (CJB) fuse 5 (10A) along circuit 22 (LB/BK). The voltage is then supplied to the anti-lock brake system (ABS) module along circuit 1651 (WH/RD). The ABS module is provided a ground along circuit 57 (BK).
