ABS Relay Cycling (operational check) Noise

Every time I start my car, within 10 seconds of driving forward, I hear an audible sound of the ABS system relays clicking. It does it very quickly, then is fine till I turn the car off. When I start again, within 10 seconds, it will cycle again. Has anyone ever experience this? It's done it since I bought the car used. No other ill affects have occured. No ABS light, no problems with braking. Just the annoying clicking sound. I jacked the front end of the car up in the garage, and confirmed it was the ABS relays by holding my hand on the relay case, while the wife put the car in drive, and sure enough, a series of quick, loud, clicking noises.

Never noticed any clicking sound but have noticed what appears to be some action of the ABS apparently performing a test when I back out my driveway. I've noticed this on occasion when pulling forward from a curb parking spot too. No ill affects but I am very attuned to any sounds that the vehicle makes. Guess this comes from driving the various 'bombs' in my mis-spent youth. Going over a bump, if something fell off, I could tell exactly what it was by the sound of it hitting the pavement :-) Oppie (2001 lw300)
