Welcome to the Forum from NH.

Lots of knowledgeable folks here who freely share their knowledge, experiences, and perspectives. Knowledge is power.

I hope that you will become a participating member in the Forum's discussions.

You are already receiving sage advice from the knowledgeable folks on this Forum.

As mentioned above, you should purchase a Tech 2 (~$350), and it will pay for itself many times over. The Tech 2 will tell you what the cause of the issue is with your 'Service Suspension Soon' warning.
