Not true. The AGS motor has no way of knowing if any one individual shutter has been removed. It has one tab on the motor that connects to a plastic bracket that controls the movement of the entire assembly. As long as the motor doesn't overextend when opening or closing, there will be no code thrown. The range of how far the motor arm can move is controlled by the shutters themselves as they have a tab on the end of them that contacts with the AGS frame and keeps them from opening or closing any further. As long as you have at least one shutter installed, controlling that movement, no code will be thrown. I've never been able to make the system function properly with just one shutter though, there needs to be at least one shutter on each side of the assembly so that the bracket system stays in place.As it's been covered in this thread, definitely don't remove the shutters from the unit. The unit will sense no movement on whatever shutter you remove and throw a CEL which will cause your radiator fan to run constantly
You're just off base in every thread this morning, pal. You were getting an AGS code most likely because the broken shutter was causing the assembly to bind up, if the AGS motor has an obstruction in the way of it's preprogrammed movement, it will set a code and make the car run the fans to protect itself from overheating from a lack of air flow to the radiator. If you've ever had the bumper off and studied the AGS assembly (and you haven't, otherwise you wouldn't be trying to argue this with me) you'd understand how it works and that there's no possible way for the AGS assembly to know that a shutter is missing, unless said shutter is causing the assembly to bind up, like what happened in your case.I just went thru this with my dealer. I had one out of the eight grill shutters broken and the car threw a CEL for AGS. They replaced the whole unit
Don't see how what you're saying debunks the notion that the computer will know if one or more shutters isn't working
I guess you can enjoy your 50+ degree over ambient IATs then while the rest of enjoy much cooler temps with zero issuesSo I guess here's the moral of this story:
If you mess with your AGS, whether it's removing a shutter or all of them, there's a very very good chance you will throw a CEL. If you're a super technical person like mr starscream here and think you can carefully remove certain shutters without messing up the whole system, have fun. From my experience, having had the front bumper off the car and messed with the AGS, I wouldn't mess with it again. Why risk overworking your radiator fan, which in turn will overwork your alternator to power it, which in turn will make your engine work harder and throw a code in the process for something that's going to have literally 0 performance impact?
LOL. Actually I'll enjoy my car not having a CEL light on and running the radiator all day. You do realize the car is able to control the AGS when it needs to cool the engine, right?I guess you can enjoy your 50+ degree over ambient IATs then while the rest of enjoy much cooler temps with zero issues
Has anyone determined whether the grill shutters open under WOT conditions yet?
