To reset the 2003 cadillac devilla security system you will start by turning the car on without starting the ignition. Open the hood and remove the fuse in the engine bay fuse panel that is labeled "ecm". Take it out for 10 minutes and plug it back in.
I do not see the ECM Fuse in the fuse box or on the whose box tap. Whatever what else can I do my security light on my car? Ignition gotta keep go at it. It's not turning all the way off. I'm assuming is the security. Well, it said it's a security thing it's on. Need help
