UC121 power train trouble code

[dport]

Does anyone have information on the trouble code UC121? Scanner says "UC121 manufacturer specific power train trouble code". No reference found so far.

Perhaps the code was incorrect and/or the reader/scanner isn't capable of communicating properly with your '07 Vue. I would presume this code wasn't retrieved from Saturn's diagnostics tool and either the connections weren't properly made or a visit to Saturn is due. Is there any reason for your concern, the Vue exhibiting engine/transmission/body electrical problems? It may help to post any problems that caused you to retrieve this code.

This code was read by an Autoxray 4000 reader with the GM enhanced OBDII package installed. No noticeable symptoms, just trying to find out if this indicates a problem or is designed just to bring you to the dealer. Apparently not a standard trouble code . No information seems to be available anywhere that I can access. It did indicate it was a manufacturer specific code.
