AlfaOBD help clearing body codes

[paramax55]

I need to clear a headlight BMC code and one for the AC compressor as well. I have AlfaOBD and OBDLink MX. I can read the codes and I click the "clear codes" button, Alfa says to make sure the key is on without the engine running, I ckicl "OK," and they don't clear. I've had BCM issues before that the shop has cleared for me, but it costs $60.00 each time they do that. Do I need the bypass cable to clear codes?

2006 Ram 3500 5.9. No left headlight and no AC compressor.

It will not clear if it's an active code.

Is an "active code" one where there is still a problem? With the headlight code, there is no problem with the wiring, the light itself works fine in the other side, and I did not have the lights on when I was trying to clear the code. So what's the difference between an active and inactive code?
