I have a 1996 Dodge Caravan.  The ABS light is lit on the display.  The
mechanic told me this did not mean anything.   Any comments?  Is he
right?

No. It means there is a fault in the ABS system. I have a '96 Caravan
as well. The ABS light is also on. If I have to make a panic stop. the
wheels can lock up. This means the ABS is not functioning.

This being my first ABS vehicle, I'm not in a panic to repair it. My
driving habits are established for non-ABS. When I have time, I will
try to look into it.

But if your driving habits reflect the use of ABS, you need to get
that looked into right away. And I would suggest another mechanic. I
suspect that your mechanic ether has no knowledge of ABS, or finds it
difficult to work on. Find someone that is familiar with ABS.

Time to find a new mechanic.

That means the ABS system is not functioning which makes a very
'radical' difference in your stopping.

Your front wheels now can lock up if you hit the pedal hard.  You can't
steer with the front wheels locked.  They couldn't lock with the ABS
working.  

If you know how to drive a skid or use threshold braking, say in a panic
stop or on snow, then no problem.  If you don't know how to use
threshold braking, you should get the trouble looked at.

Especially before driving in snow.

Even worse, your rear brakes could lock and make you spin out.

I believe that the systems still require the combination or
proportioning valve so they can still work like 'normal' brakes.  This
was introduced back in the 70's I think to prevent rear wheel brake
lock.  Jeep started using it in the 70's anyway.

As far as i know all vehicles use proportioning valves whether or not they have ABS. Unfortunately many of them are not effective. On some cars I have had they worked quite well. On many vehicles I have driven, especially pickup trucks, the rear brakes lock up very easily on wet roads.

Jeep was smart and had a variable combo valve according to bed load in
their pickups.  This was to avoid the empty bed and too much brake
issue.

You are right though, when the rear brakes lock, bad things happen
faster than you can blink.
