Hi there, thanks for your question.
This code is an IMMU-ECU code for the NATS system. I would start by clearing it and just hope it doesn't come back. If the car has a remote start it can also trigger this code.
If the code eventually comes back and the car won't start. The security light will stay on solid. This is telling us the immobilizer cannot verify the key id with the ECU. Which means there is a malfunction in he immobilizer.
