Is the a code reader integrated into the DIC on a C7 as I see in other threads that non-C5 owners are using OBDII readers.

On the C5, when a "Check Engine" light appears, it is possible to find out what is causing the light to appear by going to the DIC and finding what code has appeared. Going online provides the information to determine what the code means.

The code can be cleared through the DIC and the "Check Engine" light disappears.

This is convenient as there is no need for a trip to the repair shop/dealer or to buy and use a plug-in OBD.

Does the C7 DIC have the same capability as the C5 with respect to dealing with the "Check Engine" light?

C5 is the only car model of any ever on the market that had the ability to read all of the codes on a car (not just engine). C6 and C7 you need to use an independent scanner. An OBD II scanner can read engine codes but you need enhanced readers to read ABS and SRS codes. If you want to be able to diagnose the complete car you will need more sophisticated tools. Top scanners will support Body Systems, Chassis Systems and Engine Systems. Reading all of those types of codes involves purchasing a high priced scanner that has special software to interpret GM specific codes and to transmit commands to the car's diagnostic system.

So what is the least expensive scanner that can read all the GM codes?

I am more of a Mopar guy ( tech for 15+ years) and a scan tool to be able to read all of the codes is in the thousands..... Can buy ones to read SRS ( seat belt/airbag ) PCM, and ABS ( anti-lock brakes ) would run you a couple of hundred.

Easy and inexpensive.

I would highly recommend using a BT/WiFi OBDII dongle with a phone app. I can read and clear the codes on all of my cars using Torque app. IT also supports plugins for those codes / PIDs that are not preloaded to the app.

Well, I'm using a $12 unit, and it works great : )

Just make sure the bungle you choose has an auto-off feature.
