Help: 94 Olds OBD-I question

No. YOur car has OBD-1 1/2. You will need to hook a OBD-1 serial reader to pin 12 (M).

I have an Auto Xray unit - the blue plug works on the "OBD1.5" There is no way, short of a code reader, to get the codes out of that computer. My '94 Trans Sport has a 12 pin connector, and you can't read it with a shorting pin either.

Screwed by GM again. I wanted to stay away from buying a car made before 1996 for this very reason. My OBD-II scanner (actually a Palm) works great on 1996 and newer cars. But the 94 Olds was in near perfect condition (except for this missing problem) so I bought it.

Thanks for the resp>>

You need a computer that will read GM OBD-1 like the Actron CP-9110 with a CP-9111 cartridge. The trick is to get the 16-pin cable to use with the cartridge. (CP-9115), otherwise you are stuck with a 12-pin cable (ALDL).

Check

Any OBD-1 serial reader will work. Check ebay, etc. Some obdii readers also have obdi capability. You may have to make your own connector though.

Paul, are you sure that pin 12 is serial data and not pin 9. My reference guide shows the following diagram.

You are correct. I was wrong. I was for some odd reason thinking obdi.5 whilst visualizing obdi. Here is another link (jpg) which shows a similar aldl hookup:
