Hi and thanks for using 2CarPros.
If the light is flashing and chiming at the same time, check the IOD fuse. It is in the power distribution box under the hood. in a special retainer. This fuse controls the flow of power for the "Ignition Off Drain" by components such as a clock, PCM. If bad, it can cause this code.

Check that first and let me know what you find.
