If You have A7EB code on the dash of Your GMC vehicle that means that there is a problem that was detected with the diagnostic control module on the vehicle. This is not the same as a standard check engine light that will let You know there is a problem with the engine. Typically this code will happen when there is a fault at some point in the startup procedure of the vehicle. Usually restarting the car is enough to get rid of the code. It can also be turned on just because a sensor sent one signal that was out of range, but not enough to trip an actual check engine light.

7EB is not a problem code. Many OBD scanners show this code when more detail is required, such as which part category to search. Your engine light could have come on because of a brief misreading of the engine sensor. Remove the brightness of the Test Engine and keep an eye on it.
