I replaced my battery recently and then took my coupe to get a Smog test done for the California DMV. It didnt pass. Everything was good except for the Secondary Air Sestem. They said that since I replaced the battery that it needs to be driven for a while to allow the car to achieve its drive cycle. I drove it for 175 miles. Freeway, city, traffic.... does anyone know what I need to do or how long does it take to achieve a drive cycle?

Thanks for helping

Dan

Assuming you did some normal driving including getting a highway, perhaps you actually have a problem with your air injection system. Do you have a CEL? If so, did you clear it? Can you hear it running when you do a cold start?

Get a code reader and check it yourself before you go. There should be no codes and all monitors should be ready, and 0 incomplete. It can take some time to get 8 complete monitors. If you clear the system you may have to start over.

FWIW on my GranTurismo I followed the instruction from Maserati service (and other wise web tips) to clear the Secondary Air System status after my (used) car was delivered: drive about 500 miles. It did the trick. I checked the status using an OBD reader and my iPhone every day for about 2 weeks, and it eventually turned to Ready :)
So I was able to pass smog check (in Northern California) yesterday.

The system has to go through a few warm up cycles from completed cold start(1-4?).

Will net set with just one long drive with a couple start stops.

Smog Test

This may well very by jurisdiction but my experience in Atlanta is that the tester can make a difference.

I had bad luck with both my Maserati and my Toyota Sienna with the testing shop that relied only on the OBDII computer test. It was frustrating with repeated attempts, a trip to the Toyota dealer, drive cycles and more. This included my own pre-testing of the cars with my code reader showing all sensors ready and no faults. The OBDII only testing shop actually was unable to report the details of the fault. They would only report that the car did not pass.

Eventually the OBDII only shop referred me up the street to a testing shop that actually tested the emissions with a probe inserted in the tail pipe. This shop has been able to pass my vehicles without problem so far.

I do not know the situation in California, but here in Atlanta not all shops are the same.

Yes, it must be driven, the amount of miles varies depending on your distance from leaving that God forsaken state.

dc8333 - Try a can of BG 44K - drive 10 miles then test. My wife's BMW went from 3 fails to pass after adding a can of this injector fuel cleaner. My longtime BMW mechanic recommended it...said all the good mechanics use it. Good luck.

BG is decent stuff, but I don't see how that helps a car run the monitors so it can pass an OBD2 test.? Injector cleaner would only help in that case if the car was a 95 or older as the emissions are done on a dyno most of the time with a sniffer in the tailpipe...Jason

Monitors don't all run independently. If there's actually a problem and one won't set to ready, it can prevent other tests from initiating.

I have the same problem with my 2006 Gransport LE. I replaced the battery. Went to the California emissions test and the OBD2 data was not ready. The test station printed out a seven page set of driving instructions that would be impossible to follow with any traffic / lights, stop signs. Went to Maserati dealer. They said to ready system for emissions test:

Maserati Dealer
Drive total 60 miles
Keep at 2000 - 3000 rpm
Do in 2 x 30 mile trips with an overnight drive cycle.
Fuel tank must be 1/4 - 3/4.

When I returned to the dealer all systems were ready except for the Secondary Air Injection which was still incomplete. Dealer said drive more. I’ve now driven 180 miles over a couple months and can’t get the secondary air to be complete. Registration is now expired. Anyone have a suggestion?

Driving it anymore isn't gonna do anything really...The SAI monitor runs on a cold start only.. Such as first thing in the morning engine cold...Start it cold and let it idle for a bit for a few days and see if it will run...Seems like it should have run already for sure...Let us know...Jason

Thanks Jason, I didn't realize the cold start aspect. I am going to cold start the heck out of this thing! Hopefully after a few days of cold starts it will ready the Secondary Air. Its a relatively low mileage example I have been using for shows primarily so driving around aimlessly for hundreds of miles wasn't making me any happier than being in the rule laden no emission state of CA! Cheers.

Cool, it just needs to be dead cold for it to run that test..No need to let it warm all the way up either...It just needs to run like 3 minutes or so...I would buy a cheap OBD2 reader from a local parts place..Then you can tell if it has run it or not and not screw around with emissions station...Jason

I went through some of the same crap last time I smogged my Coupe. I ended up driving about 100 miles before it was ready for the test.

Way to go CA. You are trying to reduce smog, and you make me drive 100 extra miles that I wouldn't have otherwise. The state of CA forced me to add extra pollution to the air, so that they will give me the honor of paying them hundreds of dollars EVERY year, so I can drive MY car once in a while.
