Future GC problems?

Have a 98 3.3L Grand Caravan apex 230,000 Km's Runs well with no codes or lights, usually. Get in the thing this morning , start it up, runs great and pull away, look down and there is a antilock light on and nothing else. By that I mean nothing, not even the odometer, Speedo, tach, or other gauges, which are all analog. Drove approx 20 minutes and stopped that van. Before starting it again I checked all the fuses under the hood and pushed them all in, some moved a bit but not enough to think that they were not contacting. Figured that I would take a look at the fuses under that dash if that did not work, got in and started it up and everything works again and has not been a problem since. ??? Pending problems or just a fluke? Did not think that the relays/fuses under the hood had anything to do with the dash, but... Any ideas? Thanks in advance for your help..
