There’s a procedure in the factory manual for doing this without the TECH tool (or Gary's software). That procedure can only be used if there are no ABS codes.

Hey Gary, just wanted to say thanks again. Your tool is invaluable and I'm impressed at how much can be done with it. First time working with a scanner so I had a lot of to learn but now that I know, I can really appreciate it more.

If you follow my thread, your program was very crucial in helping me understand my car in order to deal with the emissions issue.

This software works great! thanks
I had a really old laptop with RS232 and Freescan. that died a few years back but the car has been sitting the better part of 5 years too, so I didn't need anything. I'm reviving the ol' girl and so I followed through with updating.

I used Scan9495 and made my own cable.
-I used a FTDI USB cable, 1 Diode, 1 1K Ohm resistor, and a 2-pin weatherpack type connector.. just like this write up: Impala SS Forum Post
It worked great. cable was $7 or so on ebay. diode and resistor are cheap. also, I cut off my OBD II type port years ago which is why I used the 2-pin. I had been using alligator clips to the tan wire & ground with my old AKM serial port cable.... This is a race car and I only need the tan wire and ground anyway. I soldered the components together, lots of heat shrink for reinforcement, added a 2-pin connector for car/cable and tested it all out. Works great. I also tried EEHack but I like the Scan9495, especially the ability to easily toggle fans and other components on/off for testing.

I think I have windows 10 (sorry, I don't pay attention to such things), the cable driver auto-updated from windows, and everything fired right up without a hitch.

A number of these forum posts just wire the RX and TX wires together for the USB and connect to the ALDL. I added the diode and resistor as I came across that recommendation a few times.

Thanks for the feedback. Seems like a good way to save $$$$ compared to a ready-made cable.

With Gary's approval I will add a link to this post to post #1 so the newbies can find it easi.
