Thread: GM '89 ALDL Celebrity HELP!!!! (Scanning)

okay, my car is gettin old and i need more info to be able to diagnosis problems.

I tried testing with the MAX232 chip and the RESISITOR coupled with the diode – all to no avail. Basically, I ended up bunging up my 12277330 ECM (may be recoverable since the power outtage).

The thing that I find amazing is that 89-ish GM celebritys are EVERYWHERE!!! How is it that I can find a *.DEF file for the for ANY program. I tried using ECM852 (probably a wrong thing to do) seeing as how it meesed up my ECM (it may have fix from a power cycle, but I didn’t chceck – simple the codes caused it to bung).

Here is what I have: 1989 Cheverlot Celebrity with an 1227730 ECM>

I need software that will work with it … I don’t care If I have to pay (although nice would be nice).

C’mon … people must have experience with Celebrity … there are millions of them out there.


Plesae send me any and all info that you can.

Thanks,
