Welcome to Forever Pontiac
We are a community of Pontiac enthusiasts. The purpose of our community is to keep alive the Pontiac spirit by sharing (or showing off) our cars, discussing Pontiac, helping each other work on our cars and find information, plus attend various meets/shows/etc... To aid discussion, sharing, event planning and selling of parts/cars/anything, we have various parts of the website to aid this from Forums to an online Garage to Classifieds to even a Document Download Repository. You can find links to these in our navigation above based on what each section helps with (discussion, local events, learning, etc...).
We invite you to contribute, find help or just view some of our member's amazing cars! Don't forget, we also have great contests from time to time (like our Pontiac of the Month and yearly calendar contest) and our Pontiac This OR That, a fun game where you choose the best of two randomly selected Pontiacs from our online garage.
We look forward to seeing you around!

I just acquired a 1994 Grand Prix 3.1L with 61K miles on it from a friend.
It has been off the road for 5-6 years but was being driven on site every month or so until a year ago when the right rear brake line broke, it's been sitting since. When I got it the master cylinder was empty/dry and of course the brake and ABS lights were on. I was told the ABS light was not on until the line broke and the fluid leaked out.
I have replaced both rear lines and bled the hydraulic unit and all 4 wheels. I have a decent brake pedal, the brakes work and the car stops fine - quick and straight. The problem is the ABS light is on solid. I've done some research and this means the system has disabled the ABS. I think it has latched the error from the low fluid condition and won't re-enable the system until the error code has been cleared. I've tried to clear it by disconnecting the battery and discharging the system without any luck. The ABS light never goes off, it is on solid from the time you turn the key on, it does not blink.
This is a 1994, it has the 12 pin ALDL connector and the under hood label says "OBD1 Certified". The 12 pin connector only has 3 wires in it, it DOES NOT have the diagnostic pin to display codes on the dash.
Is there an inexpensive way to read and clear the ABS code or do I need a scan tool? Is there anyone in the Research Triangle area of NC (Raleigh/Durham) that has a scanner with the correct cartridges for a 1994 gm obd1 ABS system that would be willing to do it?
