Recently I posted regarding the numerous issues with my 89 xj. It was suggested to me that I take it to my friendly local auto parts store and have them run a code scan on it. Well unfortunately I have been to several different stores, autozone, napa, shucks and they all have said there is no such thing for my vehicle so there is nothing they can do to help me:brickwall:

Ugh!!! At least I know that once again I was right lol. Anyone have any suggestions on how to manually pull codes? I hope it's not going to cost a lot of money. I feel as if I've already put way too much in to it.

Nope.. no code scanner for a Renix Cherokee...

And nope no way to manually pull a code either... (that would be OBD-1)

Renix Cherokees(87-90) have no ability to store a code. Heck.. they don't even have a real check engine light. The service emissions light(or whatever it says.) is run by a timer that is set to go off at 80,000 mile intervals.

You need a ohm meter and a little bit of knowledge to diagnose most anything wrong with the Renix system. There are several good sites out there with the info needed to take care of your Renix system. Google Go-Jeep.. its one of them.

Wrong boys. There's a code reader for the renix. But that doesn't mean you'll ever find one.

However, as whowey said, they can't store codes. So information can only be interpretted by the reader in real time. The reader you can't buy or find, that is.

So, really, you're much better off troubleshooting it the real way. The way before you could just plug something in and have it tell you to change random parts. A multimeter goes a long ways, and a FSM (factory service manual) is a great help. But, a lot of problems require neither to solve.

I wasn't going to mention the old Snap On one that is out there. None of the usual sources are going to have it and barely anyone that had one still does.

Bendix made one too.


But yeah, good luck finding one.
To be absolutely serious. Technically neither was a 'code scanner'. Both were diagnostic scanners. The Renix system didn't use the 'code' system.

The scanner you mentioned is a real thing that existed but hasn't been manufactured for many years and was way overpriced when it was available.
The whole Renix system can be diagnosed wth a $4 multimeter and hand tools.
Jeeps were meant to be fixed on the side of a trail and not in some big fancy garage. The Renix era Jeeps help the owners to follow that long standing tradition. No readers are needed and any fool can do it (I'm a prime example). Just get a few readings from various sensors and senders and know what that means and you can fix your Cherokee if it is a Renix era Cherokee.
