Mocoondo,
I agree that it is a very good business decision to disable the cigarette lighter socket. I'm just glad that I found out about it before I go on a long trip and have a breakdown and the tech/mechanic is befuddled as to why they can't get a port scan to work.
I would submit for consideration that when a CA unit is retired from the rental fleet and put up for sale that a 1-page insert be included in the P&S that informs the buyer that OBD port and cigarette lighter socket share the same fuse and that in the event that the cigarette lighter socket has no power then it's fuse may be missing or may need to be replaced for the OBD port to function.
If it's too much for CA techs to re-enable the cigarette lighter on the motorhomes being sold then CA could tape a new fuse to that insert and let the buyer choose to inspect/replace the fuse at their pleasure.
I think that giving the buyer a heads-up about the OBD port at the time of purchase would be a good thing.
