This is tough to know for sure until we scan for codes so that we can find out what the issue is. This could be a number of things so until we know what codes are there, we would just be guessing.

The only thing we can try is putting the key in the ignition in the on position for up to 30 minutes. If there are no issues with the system then this will deactivate it.

Here is a guide that will help with this:
