Check Engine, VSC, TC Lights All On

Cranked up the 07 Limited and the lights were all on. Drove her anyway, no change even after a re-start. Checked the #19 fuse, still good.

Got her home, disconnected the battery and re-set the ECM. Also checked and found the gas-cap was not "snapped" or clicked. Took it off, then re-installed with a good turn.

Re-connected the battery and now the lights are off. Am I on the right track here?

Thanks ahead

UPDATE TUESDAY

Well I took her out for a long drive today, still no more lights or codes. I am assuming that it was the gas-cap all along and that by tightening it and resetting the ECM that I am okay. Probably logged 75 miles today and all is good.
 
How, simply all down then all up? And the moonroof up or all the way back? I'm curious, why do they need to be reset?

When you're opening and closing the windows and moonroof (if you have it), hold the button down in the open position for a second or two, and do the same for closing, as well for tilt and slide on the moonroof. The windows and moonroof need to be "normalized" for the auto open/close function to work. You'll need to normalize the windows any time power is lost.
 
These lights (check engine, VSC Trac, VSC Off) all lit up on my dash earlier this week and have stayed on. Tried tightening the gas cap with no help.

Today I had an auto shop run a diagnostic check and they told me that I have 2 problems. The main problem is that the right rear oxygen sensor is bad and the diff. lock switch is defective.

Has anyone else had this diagnosis when the lights came on? Is there any type of TSB out on the O2 sensors?
