S70: ABS Brake Light on after bleeding brakes

I have a 1998 S70. I bled the brakes according to the best info I had, ABS
procedure from shop manual for 1993 240.
Now the ABS warning light on the S70 dashboard comes on occaisionally. Does
anyone have information on the proper
brake bleeding procedure for this S70?

I just replaced all rotors, pads, two remanufactured front calipers and hoses on the front. I bled the system and the brakes feel great.However,the ABS light come on after I start driving for a few minutes and the anti-slippage light does as well.

Just yesterday, the ABS kicked in for no reason as I was applying the brakes on dry asphalt.

I am bit concerned if anything is going on.

I used the simple 2-men bleed job, once wheel at a time.
