You could try disconnecting the battery for awhile and see if it resets everything when you reconnect it.

I guess the ECU had gotten itself into some spurious state that got cleared by disconnecting the battery.

You might try emailing Duram and asking him about it (he was pretty helpful when I was having problems resetting the service reminder) - he may want you to create and send him a work log from your connection.

These are separate views of the same evidence. Frequency alone does not establish a fix, and these counts must not be added together.

Coverage and how to read this overview

Counts describe captured discussions, not unique people or a diagnosis. Author identities are not reliably stored. Exact duplicate evidence is counted once across matching discussions; one discussion counts at most once per action/state. Multiple repairs reported together remain a combination. Suggestions and failed attempts do not establish a fix. Matches cover whole discussions and can include related faults, model variants and incomplete threads.

8 eligible posts · 0 unverified posts · 1 discussions match the subject in their title or opening post.

0 evidence records excluded for query context · 0 excluded by outcome qualification · 0 adjusted by outcome qualification.

2 acknowledgements have no verified action link; they do not establish a repair result.

Surprisingly there are no fault codes showing in any of the diagnostic categories, yet the CEL persists.

POST 1Original post

The dreaded check engine light came on today, so I hooked up the Durametrics software diagnostic tool to see what was up. Surprisingly there are no fault codes showing in any of the diagnostic categories, yet the CEL persists. This leads me to wonder how comprehensive the Durametrics software really is. It must be missing something. I have the latest software version (5.1.3) that's available from the Durametrics Web site. Anybody have any clue why there would be a CEL without fault codes?

POST 2Original post

You might try emailing Duram and asking him about it (he was pretty helpful when I was having problems resetting the service reminder) - he may want you to create and send him a work log from your connection. FWIW, I have had CELs that weren't even recorded as fault codes for the dealer's PIWIS to read. If the CEL stays on, then I would take it to your dealer, if I were you.

POST 4Original post

Good thought but unfortunately that's not it. CEL remains on this morning.

POST 5Original post

Try using the Durametric function which resets the service reminder. If that doesn't work I would go through and recheck all of the diagnostic parameters again for a code one more time.

POST 6Original post

I hooked up the Durametrics diagnostic again today but I still don't see any fault codes in any category and the CEL remains on. I also went through each category and did a fault code clear even though there were no codes showing, just to see if that would make a difference (it didn't). I did clear a service reminder a little over a week ago before I had the CEL problem, so I'm wondering if that could have something to do with this...?

POST 7Original post

You could try disconnecting the battery for awhile and see if it resets everything when you reconnect it. You will have to drive around a bit for everything to return to normal if you do.

POST 8Original post

BINGO!!! That did the trick. I guess the ECU had gotten itself into some spurious state that got cleared by disconnecting the battery. Santa Fe, you are a GENIUS!!! :cheers:
