From what I can tell the service brake system message should be displayed only in conjunction with the red brake waring light or the ABS light. You can try confirming the brake fluid level is full and the parking brake switch is working properly. If those check don't lead anywhere check for fault codes in the ABS module using a scan tool would be the next step.
it seems like the sensor is causing the problem check the brake fluid level is it filled to spec check the sensor.
