To reset the security system on a 2003 Cadillac DeVille, begin by turning on the car without starting the engine. Pop the hood and locate the "ecm" labeled fuse in the engine bay fuse panel. Remove the fuse for 10 minutes before reinserting it.

I can't find the ECM Fuse in the fuse box or under the hood. What else can I do about the security light on my car? The ignition keeps going, it doesn't turn all the way off. I think it's related to the security system. It's showing a security alert. I need some assistance with this issue.
