Supercharger not coming on
I have P0410 Code Secondary Air Injection Malfunction.
When driving the car or reving the engine while in P or N gear the supercharger doesn't kick in and the magnet isn't activated on the SC clutch. I was told that when reving the engine the magnet should click and get the SC on. I think this should happen around 2000rpm. Checked the SC clutch itself and it is working. Checked the wiring and seems all ok. Also checked the Secondary air pump and it is running as well (maybe unrelated to this issue).
But for some reason the computer will not activate the SC clutch and the supercharger. Something is not working somewhere...
Can anyone provide any info/diagrams on what actives the Supercharger or what does the computer check in order to activate the SC. Is there any other things that can be checked to trace the problem?
Any info is greatly appreciated.

Well that's exactly wat mine does but the way I checked was by using the small battery thats on the pass side and jumping the wires directly to the SC clutch and guess what the magnet works... But here's the problem as mentioned above the belt spins and when applying higher rpms the SC should engage but it's not doing so.
Any of you have any diagrams or other suggestions so I can get to the bottom of this? What else would prevent the SC from coming on???

Also all of u are saying that the SC will never engage while in Parking no matter what the rpms are??? I can't feel it when I'm driving either and that's why I'm looking 4 a way to solve this. Also the check engine light is on...

Check you IATS and boost via OBDii scanner and see what they are at?

I checked the 40 amp fuse and the relay and all is in working condition, then supplied power to the secondary air injection pump and got a running sound under the passenger side. So it is working. (Or am I not checking the right thing? Is the SAIP same as IC??) Someone mentioned to me that if the supercharger is working the temps should be in 200's from 210 to 240 or so. Any ways how can I check the boost from the OBII??

Listen maybe i'm missing something but I just don't feel the power that was there before. Maybe the supercharger is ok but why does the P0410 come up? After all this is what after and I was told that I need to start with the SC because thats what this is about. Like I said maybe I'm wrong and thats why im looking for your suggestions. Thnks
