2009 XK Check engine Diagnostic - Is there a record?
Hi,
I am curious if the computer saves the dates / times of when the check engine light comes on and off? Is there a record that can be run/printed out? Or does it only know the most recent?
Thanks

I suspect not, but try asking on the XK150 forum which is for your year.

It's "freeze frame" data and to some extent yes. It saves whatever it thinks may assist diagnosis.
(It may also save things you'd need the jag tool to get.)
By way of example, if a lean code flagged it can be helpful to look at the data to see if the other bank was close to throwing a code or not i.e. is the issue one side or both.
