I have a 2002 XJ8 that failed its smog test because I replaced the battery recently. I was not aware that disconnecting the battery would erase the ECM memory. This causes the sensors to report "Not Ready", and fail the smog test.

I also have an Autoenginuity diagnostic tool that I have used successfully to diagnose the ABS system and misfire issues. I want to read the Inspection / Maintenance codes to see which tests are "Not Ready". But when I select the "Onboard Test Results" tab, every parameter shows "Not Supported". Anyone have any idea what could cause this? The manual clearly shows that the reader has this capability. I have not been able to get help from Autoenginuity.

 

You may be in the wrong menu.

You want the status of each OBD monitor, which is standard OBD.

 

Thanks. Attached is a copy of the report it generates for IM / Mode 6 results.

 

You're looking in the wrong place (again)

OBD monitors are "mode" (not the correct name but it's used a lot!) 1

Thanks for the link! I will have to study this, as I've never done this before.

The smog test flagged “comprehensive component”, “catalyst”, and “oxygen sensor” monitors as “not ready”. My problem is that I need to drive the car a few hundred miles to get the sensors ready so I can register it, but I can’t drive it because it’s not registered! Here in California, driving with expired registration will get your car impounded!I’m also my wife’s primary caregiver, and can’t spend a lot of time driving around the landscape. Plus, Jaguar shops seem unwilling to fix it. Anybody know of a Quick Fix?

California would appear to issue temporary permits for non-registered cars as well as temporary permits for cars that fail their smog tests that give you time to repair and retest them.

Good luck!

 

Thanks for the tip Ken. That's exactly what I need!
