I have an 87 LeSabre. Can you pull error codes? I remember
I had a Chev Celebrity and you could jump a couple of terminals to get
the code. Is that true with Buick? Thanks

yup its the same procedure. im cant remember for sure what 2 pins u jump but i believe ist the a&L.

u prob could call ur local auto parts store and ask them to look in a code book for the correct pins to jump

Go to a local Buick auto parts dealer, they should be able to help you look for the needed codes.

When looking at the DLC plug , it's the two top holes on the right side (passenger side).
You can jump them with a paper clip.

See earlier post #6. If you need help ,just ask.
