This is common on all bikes of this era. A new battery will resolve this problem for a while until it starts to drain down after 6 months to a year or so. The problem is the ABS system needs a good solid 12.5V or better to work at start up. This is the same time the starter also needs good power which puts a heavy load on the battery. They both end up competing with one another and the ABS computer creates a fault but the bike still starts. By starting it again and again helps because the battery is quickly charging each time you start. So, a new battery can help or put your bike on a trickle charge from time to time. The problem will never be fully resolved. You need to eliminate the fault before riding or your ABS system is non functional.
