RrABS light on with dim parking Brake light
 

Iv been driving my 96 trooper s 4x4 for about 500miles now all of the sudden, when i started the engine, my RrABS light came on along with a dim parking Brake light. I checked for codes but nothing came on in my OBD2 reader. I looked at the fuse box, and on the ABS 4(wheel only) it doesnt have a fuse, should it have one?! Iv been driving all along & these lights never lit up on my dash. Then, after 20 mins the Rr,ABS & parking brake disappeared for 1 min, came on, then when off again while i was driving. Im so confused, please help.
