You read codes from the engine computer in the odometer display. "Done" means it is done displaying those codes. You need a scanner that can access the air bag computer to read the codes in it.

Thank you for taking the time to answer the question. Your answer was very helpful. Can an OBD 2 INNOVA tool with SRS feature be used to access the air bag computer? Thanks

Chances are it will not. OBD2, (on-board diagnostics, version 2) emission system started on all 1996 models and standardized a lot of stuff, but by the mid 2000's, the industry had switched to the "CAN BUSS" system which turns every switch and load into a computer module. Every 1995 and older brand spoke their own language, and scanners of that time needed to be able to understand all those different languages. The clue is every car brand used a different scanner connector, and there was no standardized place you would find them. It was up to each manufacturer where to hide them.
All OBD2 vehicles use the same scanner plug, and it's always under or near the steering column. CAN BUSS vehicles use the same plug in the same location, but the computer language is entirely new. That means every repair shop had to run out and buy new equipment. Some of the newer scanners can be used on OBD2 and CAN BUSS systems, but they are very expensive.
I have a Chrysler DRB3 because it works on all of my vehicles except a newer truck, and it will do emissions-related stuff on any brand of vehicle 1996 and newer. For my 2014 Dodge truck, I use a friend's Snapon Solus Edge. Innova makes a number of different model scanners and code readers, but if yours only does OBD2, I suspect it will not work on a 2007 model. We started changing to CAN BUSS around 2003 to 2006. I do know my DRB3 will work on some 2007 vehicles, but I do not think there is any 2008 model it will work on.
If your unit can access an "air bag computer", it is more than a simple code reader. It will not hurt to try it. At worst it will just say it cannot communicate, or you will get a message, "No data buss".
