I no longer have the old ECM. How do I determine if it isn't a diode or other problem of this type ?

Sorry, I am sure there could be a multitude of potential issues. However if the lock symbol is showing I would look at areas related to the vehicle security first, as in the key programming. If you know someone with a higher capability scan tool or Tech II you may be able to get a more detailed diagnosis or re-learn. Sorry to say I do not have more ideas on this.

Curious?
Why did we replace the ECM?
Just wondering if related.
