What does it mean when your four wheel drive light keeps flashing along with the anti lock light flashing on a 2001 Mitsubishi Montero sport?

I don't have a 2001 Montero Sport, but I just recently bought a 1998 Montero Sport and it had this problem while I test drove it over night. I told them to fix it before I would buy it and they did. It was some problem with the actuator or whatever engages the transfer case, they had to replace that part, and fix something in the brake system in the engine compartment. It took about 1-2 weeks to fix and a $1000 or so (out of their pocket of course). The basic problem was that the transfer case had trouble staying enagaged and when it did, it knocked out the ABS system. If you do have it fixed though, be sure to check your brake connections in the engine compartment, as they hadn't tightened down a connection enough and I had been losing brake fluid. Sorry, to answer your question, it most likely means a repair to your transfer case components and your brake distributor block in the engine compartment Sorry, if I got any terms wrong!
