  1. It's new and cool right now so I don't mind helping out... On the truck thing, yeah been doing that for 40+ years...
  2. I got a used Solus Pro for just a little more than the mt2500s were selling for. It came with the battery and charger, the obd2 adapter with a good selection of keys and a few obd1 adapter including the GM-1 I needed. It's nice and easy to use but it does a lot so I will be reading the manual when I get a chance. Software is stored in internal memory so no cartridges to mess with. Mine is updated to 2011. Snap-On sells upgrades to current models (2016 is latest so far) but the upgrade is very expensive.
  3. Making some progress... Got a scanner today and pulled ABS codes - shorted/open left front wheel speed sensor (25). I pulled the sensor and it tests as an open circuit. I'll replace it and hopefully I'll be on to the next problem. Cars don't like to sit... Thanks for the help!
  4. I don't have the service manuals as I just got this car. I'm looking for a scanner, either the mt2500 or an OTC 4000E. I've seen some for sale but hard to find ones under $100, any of those seem to be just the scanner without any cables or cartridges or they are being sold "as is" untested, no return. I can't spend $100 for a paperweight. It's also hard to spend much more on a scanner that will get very limited use. Can someone give me some info on the scanners? I have seen some references that imply that you need a specific ABS cartridge in addition to the engine cartridge? Anybody know if that is right? Will any GM cartridge 1994 or newer handle my obd1 GP, all systems including ABS? What are the keys for and would I need the correct key also?
  5. 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? Thanks.
  6. Hi, John here. Just acquired a 1994 Grand Prix 3.1L with 61K original miles. I need some help with it so will be asking some questions in the discussion forum.
