Its usually one of the x4 wheel sensors
- but could be dirty phonic / tone rings on drive shafts
- or the magnetic pickup shown above, usually you will not see damage to the black plastic coated sensor shown below
The thing is your description of braking hard being the cause does not fit unless the securing bolt in the wheel sensor itself was loose causing the damage. You really need to find and test the particular sensor to see if it works. Do you know anyone with a diagnostic scanner capable of reading ABS on your year Chrysler ?

Like QinteQ says if ABS light comes up its the sensors, but after ABS doing its job on a hard stop it holds the ABS light on. So whats the answer here, does system need a hard reset, be interesting to see what happens. Or has ABS system woke up after working, saying to itself, I've not been working properly, tests itself and concludes, one sensor slightly out on return voltage, so lets apply the light...

Driving on wet roads can cause the ABS and Traction Control indications. They can go off again all by themselves when the weather dries out.
This isn't a technical diagnosis, just a coincidental fact.

The light[s] as both Goggy & AlC say can / may continue for sometime afterwards until the 'x' many known to be good diagnostic start-ups are re-registered. A re-boot of the puter in my view never does harm - only ever good. [radio code dependant]

If you cant get the fault codes read then the first stage would be to use a multimeter to read the resistance of all four sensors. Follow the wires up from the sensor and find it's plug, disconnect it and read the resistance across the pins to the the sensor. All readings should be the same, if one is different then replace that sensor.
If all the readings are within a a few ohms of each other then take a small wire brush to the toothed rings that the abs sensors use to detect the wheel speed.
Beyond that there is not much that you can do without having the codes read.
