Hi there. If your Check Engine Light was triggered on your DTS, then you should have a professional reset the Check Engine Light before starting the vehicle. However, if there was no error light, you should be OK to start your Cadillac.

If you want to play it safe and ensure the repair was completed correctly, contact a professional mechanic and have them complete a Check Engine Light inspection. This will allow them to download all stored error codes and clear them upon inspection.
