2 More Monitors Not Set After Repairs, 1998 v70

[tryingbe]

Ask, you'll never know.

My friend just passed emission here without obdii readiness here in AZ because the emission people looked at their book and see this is normal for a Volvo.

[MrAl]

Don't ever get a BMW , Al. Those things store more latent codes than (bad joke deleted ) Volvo . I think it generates its own so that when the mark takes it to the BMW dealer, you get an 8 page printout and a $2000 work order

Hi,

Wow, that's nuts too. I'll stay away from them

Hi,

Ask who, and ask what?

They tell me 2 monitors incomplete is allowed with this car, and that's what i read too, but what i read was a year ago so that may have changed. But i just dont know how to find out for sure.

You have to check with your state DMV. The EPA makes guidelines for emissions testing but the States are not obligated to follow them.

Hi again,

Oh that's very interesting. I think Cristy made some new rules for the inspections this year too, which may go against some of what Washington had to say about that, such as no inspection for cars 1995 and under within a certain weight class.

I guess i'll have to re check that information.

Thanks again.

I found I had to arm myself with the NY state regs, then educate my garage on this too. I've been sent on the drive cycle for one monitor not ready before until I learned this stuff

There, I did the leg work for you.

Exclusions from Readiness and/or OBD
The OBD system monitors the status of up to eleven emission control related
subsystems by performing either continuous or periodic functional tests of specific
components and vehicle conditions. The periodic, or non-continuous, monitors only run
after a certain set of conditions has been met. The algorithms for running these noncontinuous
monitors are unique to each motor vehicle manufacturer and readiness
monitor and involve such conditions as ambient temperature, engine coolant
temperature, and vehicle speed. When a motor vehicle is OBD-tested, these monitors
can appear as either “ready” (the monitor has been evaluated), “not ready” (the monitor
has not been evaluated), or “not supported” (the motor vehicle is not equipped with the
monitor in question).
New Jersey follows the USEPA’s document “Performing Onboard Diagnostic System
Checks as Part of a Vehicle Inspection and Maintenance Program”, June 2001, (see
Appendix IV). This guidance allows two monitors to be “not ready” for model year 1996
through 2000 motor vehicles and one monitor to be “not ready” for model year 2001 and
newer motor vehicles. For gasoline vehicles, New Jersey requires that all three
continuous monitors must be supported and ready. Motor vehicles deemed not ready
fail the OBD test.
The process of determining the applicability of various readiness and exclusion criteria
is explained in more detail below.
During an OBD inspection, if the OBD analyzer successfully communicates with the
motor vehicle’s OBD system, a check is made of the engine’s RPM to ensure the
vehicle is being tested in the KOER position. The RPM check minimizes the chance of
a vehicle falsely failing the OBD test because it was tested in the KOEO state.
Exclusions for RPM are also included in case requesting RPM from certain vehicles
causes a problem, or simply the vehicle does not support the request. Currently, the
only vehicles excluded from the RPM requirement of the OBD test are gasoline/electric
hybrids.
Next, the analyzer will retrieve information to determine the readiness status of the
vehicle. If the analyzer indicates that the motor vehicle does not meet the USEPA’s
criteria for “readiness”, that is, if the vehicle’s OBD system does not indicate that the
critical number of supported non-continuous readiness monitors have been set, the
motor vehicle is deemed “not ready” for an OBD test which is a failure. If multiple
modules respond to the request for readiness data the results from each module are
combined using ‘inclusive or’ to provide one result. There are certain year/make/model
combinations of vehicles that have known readiness problems. These vehicles are
exempt from the readiness component of the OBD test, but still subject to all of the
other components of the OBD test.
New Jersey’s current system also states that the three continuous monitors, which are
Fuel System, Misfire, and Comprehensive Components, must all be supported and
ready for OBD tested gasoline vehicles. The intent of this criterion is twofold. First, it
identifies potential tampering of the OBD system. Most Powertrain Control Module
(PCM) performance upgrades disable one or all of these monitors to avoid MIL
illumination when other engine parameters are changed that would normally trigger the
MIL to be commanded on. Second, this criterion also ensures that communication with
the vehicle’s PCM has been established since Fuel System and Misfire monitors are
only supported by that module type.
For those OBD motor vehicles with known readiness problems, New Jersey maintains a
lookup table on the inspection analyzers that will ignore readiness status on those
vehicles. Vehicles with known problems with continuous monitors can be excluded from
this requirement using the same lookup table. The current exclusion table for OBD is
found below, and can also be found on our website at
http://www.state.nj.us/dep/bmvim//bmvim_gas.htm, under the link “OBD testing
exceptions”.
Currently, 84 of approximately 20,000+ OBD eligible individual year/make/model
combinations are completely excluded from readiness testing results (OBD Scan still
attempted). There are an additional 82 individual year/make/model combinations that
have been excluded from the continuous monitor readiness portion of the OBD test.
There are a total of 166 entries on the table.
This lookup table is also used to exclude motor vehicles with known communications
problems from the OBD test. For those vehicles unable to communicate, the MIL itself,
rather than the MIL command status, is used to determine pass/fail status. The visual
MIL checks still apply even on these excluded vehicles, therefore if the MIL illuminates
continuously or flashes in the KOER position the vehicle will fail the OBD test. The
vehicle will also get a TSI tailpipe exhaust emissions test, and the final emissions result
will be an aggregate of the visual MIL checks and the TSI test results. In the current
system no vehicles have been excluded from OBD communications.

NJDEP’s OBDII Exclusion List

Hello again,

Thank you very much for linking to that document. I think i tried to find that once a while back and all i found was a short version that just said "two monitors not ready is allowed" but that's it. This new doc seems to have a lot more comprehensive information. Thanks so much for that.

There are a couple things i still dont understand here.
First, they are stating that the two monitors that are allowed to be not ready are two of the "continuous" monitors, but all of the "non continuous" monitors must be all ready.
So, how do i know exactly what monitors are considered "continuous" and which are considered "non continuous"?

I do know that the non continuous ones do not run as often as the continuous ones, but that's all i know at this point.

For example, is an "oxygen sensor" a continuous or non continuous, and how about the "cat converter" monitor?

They do say the continuous are "Fuel system, Misfire, and Comprehensive Components" but i dont really know what that really means, except for the misfire which i guess is if the engine misfires?
That is, how do these relate to the readings i get on the little OBD2 tester?
I dont remember seeing "Fuel System" on the tester for example.

As you probably guessed, this is my first car ever with these friggin' "monitors".

Thanks much again.

[abscate]

The misfire, fuel , and component monitors are continuous - all the others are non-continuous type.

Hi again,

Oh ok, but they why do some of them come back to 'ready' so soon after a total monitor reset?
I have to look at my pics again. Some of them i noticed come right back to ready after i reset, and i have to reset all of them at the same time because my little tester only does that, i cant reset just one or two.
Yeah the misfire is one that comes back to 'ready' right after the reset, on the first scan after the reset.
