I think I need a little help/advice with my AIC/APCM.
I'm not having the typical error messages. As a matter of fact, the unit powers on fine, and I can go through the motions to idle my truck up. I chose my RPM, hit the ford button, then it displays that RPM, as if the truck is idling up. Problem is, it doesn't start idling up. It displays a higher RPM as if it's idling higher and I think the AIC actually thinks the truck is idling up - except it's not.
So, I don't know where to start looking to find the problem. Any ideas? It's on a 96 Superduty so it was factory installed.
Manual trans, clutch isn't depressed, and parking brake is set.
Oh yeah forgot to say I don't have a "brake" light come on when I set my parking brake. So maybe the truck doesn't know the brake is on therefore not idling it up? I guess that's a possiblity, but it seems to me that if it didn't detect the brake, it wouldn't display the truck to be idling higher as it should be.
Any ideas? Sorry for the long post.
