I have a 2002 Pontiac Montana with the same exact issue. My mileage is also around 87k.
I have brake lights, but I pulled and reseated the bulbs and connectors. I also cleaned the battery/ground and reseated the ABS sensor connectors near the hubs. All connectors looked good.
I borrowed a friend's ABS reader and it shows the wheel speed sensor was out on the right front so I replaced it now it all works! Just thought others should know.
