Curing some codes on 07 599 GTB - step by step

So far I am enjoying my Ferrari experience with my 599. I am working to make the car perfect for me. Many of you have been helpful and I wanted to share my work for those that may need it. My X431 has been a great tool for this car (and for a couple of my Porsches as well!).
Two main things I am working on:

1. Siren not chirping when locking. B1026 error code (Siren). Error only comes up if I lock and unlock the car. Took the front bumper off and removed the siren. Battery had sulfated and possibly affected the electronics. Ordered Ferrari part number 295120 From Scuderia (had the best delivered price) which is the entire horn and electronics. Will report back on it once I replace it.

2. This one I am still considering proper course of action. Series of codes: P1439 (LH-B secondary Air Injection System (incorrect Flow), P1444 (Secondary Air Injection System - Cyl 7-8-9 Incorrect Flow), P0492 (LH-B Secondary Air Injection System), P0491 (Secondary Air Injection System - RH Bank). I don't think its either of the two secondary valves because I am getting failures on both banks. Data pointing to one of these possible issues:
- If I am lucky, it is the solenoid valve (PN 315769). Is there a simple way to test this with the X431 (open it /shut it). If not I may just take it off and test it on the bench. I presume its just a 12V actuation. Any experience testing this is appreciated. That would be a $60 part.
- If I am a little less lucky, there is a leak in the system of hoses. I will do smoke test with my smoke machine as my second step. Any number of hoses or connectors could be the culprit but likly to be before any Y junction splitting the air injection to the respective banks.
- Worse case its a faulty secondary air injection pump. It is either PN 181197 or 247795. Apparently both pass the VIN check but it will be over $600 in parts. Same question: is there a way to isolate and test this pump on the X431 or do I need to take it out and test on the bench?

Thanks in advance for any expert advice.

My exhaust has the stock components at the headers, collector, cats (incl first and second O2 sensors). The secondary cats have been removed and replaced by straight pipes (again, secondary cats only). The remaining exhaust system is a factory HGTE system.

 

Further info: the vacuum system is working, because the exhaust solenoid valve (2) opens up properly. So back to either the solenoid valve (1) or the actual secondary pump as the likely issue. I will research ways of testing these components in situ.

Thank you Sammy. One other thing to check is the air pump relay (I think, I dont have the wiring diagrams). Will do the cold start tomorrow.

 

They are set up normally so they are closed in the low rpm/low load condition.

Mine is a 2007. I am using an X431. There are software versions for each of the modules, the engine management module has a SW version 0010261, on a Bosch ME 7.1.1 as shown in the pic below. No idea if this is recent or what it means. I could not find a way to actuate the SAI for the Ferrari (there is a way to do it on the Porsches), so I will resort to a cold start with the SAI pipe disconnected to see if the pump is blowing air. If it is not, that is my culprit.But now I have gone from a $600 part to a $200 part thanks to George. Headed in the right direction.

UPDATE: 60F / 16C - The secondary pump turns on on cold startup and remains on for 10-15 seconds; apparently everything works but shuts off rather quickly. Will monitor to see if the light comes back on. In the past it has come on after driving it a couple of miles and a few minutes.

 

I have seen the yellow ones here called secondary cats, those are the ones I meant. The cats that are part of the exhaust manifold (red ones) are primarily responsible for emissions control as they have O2 sensors before and after. The yellow ones have no effect on the computer calculations for emissions, hence they are commonly referred to as secondary. Potato / Tomato

Sammy, It is difficult for me to come to terms with this but it seems like the problem has resolved itself. I am driving the car multiple times a week and the issue is not reappearing. In fact a prior traction control failure has not appeared in over 400 miles of driving. I do have to say that the only time the check engine light came on with this specific code was 5+ minutes into a drive where I would assume the cats were already hot and there was no need for extra air injection.

I don't think this is related but when I received the car it was overfilled with oil (about 1300ml too much, they probably measured it incorrectly). This seems to have had a couple of effects: 1. oil in the intake is now gone (this one makes sense). 2. The seeping of the valve covers seems to have diminished or disappeared (this one is a little bit harder to correlate) and 3. The air injection related code no longer appears (this one I have a hard time linking).
