Drive Clean now moves to OBDII testing: Watchout..

[ckc123]

FYI: In Jan 2013 the Drive clean testing will now move to the OBD II monitoring instead of the tail pipe..

There is a very good report from Environment Canada on it..

one of the concerns is the section on "Tampering"

if you reset the MIL/SES light without doing the "required" work, then it's considered tampering of the test.. Be careful....

I can't seem to find any specifics on which PIDS are used and what the pass / fail criteria is for each.. I have the Torque Scan program, and I pass across the board on the tests, but I'm not sure what values are used for the ontario tests.. does anyone have them? I wonder if you can get them with a freedom of info request...

My OBDII tool has Emissions Pass Fail on it. I doubt matches up with the Ontario regs but I'll look into what it is looking at and how each of our vehicles reads when connected.

I've got one as well, but like you , it uses pass fail criteria which I doubt matches the Ontario criteria.

I am not sure if a "reset" is considered to be tampering. If you reset you could be pooched anyhow. ODB II has to log a certain amount of test points (warm-ups?) before it says the pass/fail for that reading is valid. So if you reset just before testing then the readings won't be (or should not be) valid and you won't be given a pass.

That's my understanding of it.

If push comes to shove I think i will change my mailing address...to Sudbury!

you are correct.. they use the term "monitors" in the document, and if you do a resent any time close to the DriveClean test you would have to drive the vehicle enough to get all the monitors as "ready".. according the document you can have up to 2 monitors "not ready" and still be able to do the tests, any more and you automatically fail it..

So if my vehicle...the V70...is running perfectly no codes except a faulty ambient temperature sensor that throws a code for the first 2 minutes and I reset it I should pass? This is assuming this will cause 1 "monitor" to be "not ready" with the remaining "monitors" functioning normally.

[Snafu]

Can you only reset one code or will it reset everything?

[Miner]

Good question. I'd have to pull a couple of sensor connections, to cause multiple codes, to find out.

[ckc123]

weird.. it lost my original reply.. it's my understanding that when you do the reset, it resets all the counters.. regardless of the original DTC code.. so you would have to drive it again, and hope that the specific monitor you want to "hide" is one that takes the longest.. I'm not 100% sure of this though..

This has been my experience as well. It behaved this way when I was diagnosing and replacing my 02 sensor last year. Even though I only had one code when I erased it with my scanner it completed reset the computer and all of the "monitors" were reset as well. My cheap little scanner can tell you what monitors have gone through their required cycles and are "ready" and which aren't.
