Brake Abs Warning Light problems of the 2002 Nissan Maxima

Abs light came on when I was driving to town. Brakes seemed to work ok, so I continued. Got to town (40 miles), did my business, got in the car to go home. Started car, abs light still on, drove 1 1/2 blocks, applied brakes as I approached intersection, and the pedal locked. Tapped the pedal, still locked. Car felt like it was still getting throttle. Put it in neutral, pulled the emergency brake, and luckily stopped before the intersection. Pulled into a parking lot, pushed the brake, and the same thing happened. Parked the car, and turned it off. Then, I decided to move it to another location in the parking lot and leave it for a tow truck. When moving it, I pushed the brake again, heard a noise, abs light went off, and brakes worked again. Drove home. I am going to take it to the shop soon. Could have been a serious accident.

When I first bought the vehicle, the abs light was on, I was assured by they sales person that it was a "minor sensor problem" in that regards I took the vehicle. When I came back to have the light checked I learned that it was something more serious since there was no "computer code" and according to the computer the car had nothing wrong with it. Manufacturer replaced abs control unit and say car was ok. After a few days the car's front wheels starting to lock at low speeds, about 25 to 30 mph. When approaching a stop sign and applying the brakes a screech will come from the wheels, some times it will be coming from the left some times from the right side of the car. Locking of wheels was only once to three times a day. Contacted Nissan consumer affairs and they said to bring the car back. After a cople of days of contacting Nissan the abs light came on again. Once at the dealer, Nissan determined that there was no output ground to light and that no code was coming on. This happened and 1588 miles. At 2054 miles car was taken again for abs light on, once again there was no code coming from computer, in other words computer was saying nothing was wrong with car. Nissan replaced engine harness on vehicle. About 2 weeks later, after that repair, front wheels started to lock just as last time. . It will only lock for one time or two a day,, but same problem, this time abs light is not on, Nissan was contacted and say nohting is wrong with car since the light is not on. On 08-14-2002 when driving vehicle out of a parking lot, speeds of about 15mph, pressed gas pedal, car is not responding ( there seems to be no traction on wheels for about 10 senconds) then "slip" light starts flashing for about 3 seconds, after this vehicle starts getting traction again and light stops flashing. Will meet with Nissan representative on 8-15-2002.
