I now believe that to not be true, because each step the ECU step is testing for specific parameters. My previous understanding was that each step of the driving procedure must be a seamless transition from one to the next. I followed the FNA 20 driving reset procedure, paying particular attention to the step that outlines driving at 2500 RPM in fourth gear for 3.5 miles then gradually accelerating to 4500 RPM then slowing (without clutching or braking) to 2000 RPM. #Secondary air system monitor codeHappy to help if you have to go through this process.Īlthough this thread originated with a concern for a 612, perhaps it may be helpful that I was able to clear the secondary air readiness code on my 360. Then you end up where I am at, trying to solve the problem for "next time". Be aware, this process takes about 3 months and so you have to take your car to the Smog Referee on expired tags just to add to the fun. If you pass the test then you will get a one time exemption. The Smog Referee will send you to one of their in house testing stations and subject your car to a tailpipe test (at Golden West College for us in Orange County). The information regarding the program and contact points for the Smog Referee are: If this happens to you then you can get a failure report from a smog station, take your car to a Ferrari dealer, if they can't fix it then you can get them to give you a letter and then you go to the DMV "Smog Referee". Most other states allow one monitor not to reset (as did California up to that time).Īpparently it is a common problem that a monitor does not reset (not isolated to 612s or even Ferraris). Jes, my layman's understanding of the situation is that last year California started the requirement that all of the car's monitors must reset to ready status. I know thats a lot of technical talk but hopefully it helps and gives you some options. Changes in the smog laws a little over a year ago has caused a flood of cars not to pass and need extra work. They needed all that and more and still took about two weeks and 200 miles of specific driving to set the monitors. I have had cars that had no faults in either Ecu. Your Dealer is obviously going to charge for that work but there is no way around it. Then after all that is verified and in good order the Ecu's need to be reset and a very specific test drive needs to be performed. Make sure there is no leaks from the pump to the mechanical valves, you need that air pressure to be as high as possible. There may be excessive carbon built up in the passage from the valve into the exhaust, blow compressed air through to check and clear out while replacing mechanical valves. The mechanical valves for the secondary air get carbon clogged and do not always open all the way, they may need to be replaced. The oxygen sensors themselves have to be in good condition and not slow or lazy. lots of cars have a slight leak at the exhaust manifolds that keeps the monitor from setting (too much oxygen read by the O2 sensors). The parameters are so tight! Your exhaust needs to be leak free, especially on cold start. It is one of those issues where it sometimes requires multiple very minor repairs and finally it will set. Ron, That era V12 engine is notoriously difficult to set secondary air monitors on. #Secondary air system monitor driverThis is my semi daily driver and I have driven it several thousand miles since and the Ferrari dealer has checked it monthly and it will not reset.ĭoes anybody have any ideas what I can do? It appears to be a computer/software issue. However, they said they will not do so again and the secondary air must reset. With this in hand the DMV's Smog Referee performed its own physical test and confirmed that the car did not in fact smog and gave me a one time exemption. Performed electronic engine control test. Finally they issued the following report: "Verified secondary air monitor will not set. I worked with the local Ferrari dealer and they tried on multiple occasions over a two month period to get the secondary air to reset. Essentially the vehicle wont pass smog inspection because the computer's secondary air monitor will not reset to ready status even though the vehicle mechanically is fine and does not smog. I went through the smog check process to get it registered and have a huge problem with the secondary air resetting. It was a Florida car and I had it shipped out to California. Unfortunately I have not found any that address my specific problem and I was hoping you have some suggestions.Ībout 8 months ago I bought a 2007 612. I have read a lot of the threads with great interest, especially the ones about secondary air resets for smog checks.
