2002 XK8 ECM and VCATS info
 

Have you looked at your vcats label?

A dealer can't 'look it up'. The JEPC will state that the last 3 digits (suffix) will need WDS to interrogate the module or the VCATS label.
The part number will show up in the JEPC but the suffix will not.
What happened to the label in the boot?

I have looked everywhere in the boot for the label (under carpet, under spare, etc). Cannot find it anywhere. This Jag was my father's for the past 20 years. He passed away, and I am trying to get it running. ECM not working properly, so won't crank. But car is in immaculate condition.

Thanks for any advice.

How old is the battery? Does it have 12.5V or more with ignition off?

I installed a brand new battery last month.

The VCATS label is in the spare wheel well on all XKs.
The 4.2 liter cars do not have a VCATS because the VID block has all the info.

thanks for this info bob. I have looked for vcats in spare well many times out of curiousity. Now i know why i never found it
