Third time to emissions still no pass, no fail
can see which ones with a scan tool and then you
have to dope out what's keeping them from completing.
The Helm manuals have good info on these details. It
is possible that your "code killing" has been done in a
way that doesn't set a light, but also makes it
impossible to complete one of the readiness tests
(Enabled, No Error means the particular test "passes"
and feeds the Readiness rollup with "all is well";
Disabled gives you no light, but the Readiness test
that looks to that test gets nothing so cannot get
to its happy place).
So, find the failing Readiness, get the list of code
dependencies, check the each of the relevant code
modes for unhelpful "kill" mode instead of happy
"enabled, no error", and then drive the hell out of it
(might read up on the Drive Cycle to get more for
less).
I had a 2000 Ws6 do this same exact thing. It ran and drove, but every now and then the computer would reset. I went to get a sticker, and it said the same thing. It turns out the ground cable had a break in it, and was only grounding itself partially. I replaced it, and everything went back to normal.
