If you have a scanner only capable of reading OBD II codes you don't get a full diagnostic picture. You need to be able to read the ABS, Air Bag and Chassis/Body codes to get a full picture. ABS and Air Bag codes will cause a warning message/light but the other ones don't give any indication other than something not working correctly. To fix those items you need to know the code.
What is interesting about modern cars including the Corvette is that powertrains are so reliable nowadays that most failures occur outside of the OBD II realm.

The OBD standard just states that a sub-set of diagnostic codes are assigned to specific things. It also mandates that you can read emissions related faults.
