JDS codes for 1994 XJS

, ,

I have a “check engine” light and found code of PP69 on my trip computer. I have found several sources and all seen to describe different problems and “fixes”. If anyone has a copy of the codes or where I can get a list of codes from PP11 thru PP99 please send them to me are answer this post. Thanks, billwhis1

It’s FF69 probably. If you’re in New England, I have a 90’s Jaguar PDU dealership computer at my shop.



You are right it should be FF69 not PP69. I would like to correct my post but I do not know how to go about it. Sorry, however my understanding of code still exists and I am confused and don’t know how to correct the problem because I don’t know how. Thanks for your help.

Basically the code means your battery is getting old,

Hi William, there should be a small pencil icon on the bottom right of your original post, this is the edit function.

I’ve moved the post to #xj-s for you.

Jaguar issued a TSB when I worked at the dealer years ago.
