Default Smog Checks, New Batteries, and Completing OBD-II Self Tests Quickly

I needed a smog check on my 2001 4Runner which had recently had a new
battery put in. I don't use this vehicle much. The technician couldn't
do the smog check because two of the OBD-II self-diagnosis had not
completed after the battery change (which erased the existing data in
the "Readiness Monitors"). He said to drive it around for a few weeks
and take some long trips.

It took over a month to clear the codes. When I went back for the "free
retest" he told me that they only allowed 30 days.

You can find the precise instructions for getting the self-test to
complete in various places on-line and it involves specific drive
patterns, see
<http://www.obdclearinghouse.com/documents/newdocuments/toyota/TSB_EG003-02_%28revised%29.pdf>.
I didn't realize this until I declined to pay the same smog check place
a 2nd time and went to my relative's shop (which is about 45 miles away
so I didn't want to go that far the first time).

Also, I did not realize that one fault code is allowable on 2001+
vehicles in California, and one code cleared rather quickly.

While I'm all in favor of reducing smog, I have to say that the
regulations of the California Air Resources Board can be maddeningly
complicated. The problem is that the law that created it, signed by
Governor Ronald Reagan, did not limit their power.

You ought to be able to smog with two monitors still running. There are 10
or 12 monitors, and you can smog without all of them being completed.
Certainly you can smog with one still running, but I'm pretty sure you can
smog with two of them going.

The monitors take a certain number of drive cycles, where the drive cycle is
specifically defined as lasting for time, distance, and speeds. You do not
do a drive cycle just by starting the car and taking a trip down to the
corner store for another 6-pack, you have to get on the highway and attain
speed for time, then the car has to be stopped (parked) for time and then
started again. The point is, if your trips are short and slow then you might
not complete a specified drive cycle that completes the monitors.

The point of the monitors is that you cannot reset the Check Engine light in
the parking lot of the smog station, then go inside and arrange for a smog
check -- you must drive the car long enough for the monitors to go away.
Again, you can have two of them running because if they still had trouble
after the other 8 or 10 are resetting, they would have reported it by now.

I think somebody is yanking your leg. In Calif., we have the Bureau of
Automotive Repairs. You can call them and they will tell you if you are
allowed monitors to still be running, and how many. I think the smog shop is
in error and they should be testing yoru car for the fees you have already
paid. I once removed a carburator and replaced it with a fuel injection
system that is CARB approved, and the smog shop screwed up the test and I
failed. Basically, he told the machine that the car was modified and this
set off the red light with FAILURE blaring from the megaphone. What he
should have done is looked that the required parts were removed and
different required parts were installed -- the visual portion of the test --
and then tested as a '94 engine instead of an '81 engine. I called the BAR
and he helped me get this straightened out. I also have a '94 (different car
than above) that failed, and the guy from the BAR said that the car was not
tested properly. The shop agreed that the BAR was telling me the right
stuff, and that they did the test differently, so they tested again and the
car passed. Barely, but it passed.

It depends on the state and the year of the vehicle. For California,
it's only one if the vehicle is 2001 or newer. Older vehicles are
allowed two.

I smogged a 2000 323i with two monitors running. Apparently this is before
the cut-off date.

What monitors do you have running?

And, do not do another reset before the monitors are complete because any
reset makes the monitors begin again.
