I know someone will probably shout "Search Button" at me for this, but I couldn't find an answer.

Would this tool work to read my OBD I system codes? After my most recent CEL light in my 91 XJ, i did the key trick and thought codes 12, 21, and 41 were actually just a code 37. Here it is:

It says it had a Chrysler interface. And 91 was when chrysler did the ECU stuff for the XJ wasn't it?

Thanks for the help guys.

 

Wow i have not seen one of those in a long time... i keep telling myslelf i sm going to buy myself one... and for that price you really cant go wrong...

 

1991 is OBDI.

The ad for the item says OBDI and OBDII, so if the ad is accurate, then yes, that will work on a 91.
