I took the plunge and spent the money on AutoEnginuity, with the Enhanced Chrysler Diagnostics package, nearly $500.
1st thing I put it on was my 2002 Mini-Van that has had that airbag light on for several years now. Within seconds it pulled up the codes for the airbags, it was a code for an open circuit to the passenger side airbag. I had cleaned that connector at least 3 times over the years, and the light goes out when temps are below freezing. I decided the connector must NOT be making solid enough contact to pass the self test (just resistance too high will fail the test). Took the connector apart with a small screwdriver, and then bent the tabs to put more pressure on the connections. Put it back together (using cell phone pics as reference so the wires didn't get mixed up) and sure enough, the next start the cell bag light went out. And it has stayed out. Probably a half hour from beginning to end once I had a good scantool (Keep in mind, the scan tool hasn't paid for itself yet, I will use it a lot in the future, but if this was all I needed it for, it would have been a lot cheaper visiting the dealer).
My mini-van has a dozen connectors and they are a bright yellow color to differentiate them from other electrical connectors. I'd assume the Commander is the same way.
Cleaning all the connectors, can't hurt, but in the case of my mini-van it took a lot of time and it didn't work, which is frustrating. Soon as the scan tool narrowed it down to one connector for me, I was able to figure it out and fix it.
