Service Vehicle Soon Light on an 06 Montana SV6

Hello,

While searching this forum for my answer I came across a similiar topic at (http://www.automotiveforums.com/vbulletin/showthread.php?t=348059&highlight=Service+Vehicle )

The question asked was if an update to the code would resolve the issue. The code that the dealer found from my van was B1390. I found some causes online but the dealer says that just a software update was required. Should this be enough of a solution or should I be expecting this error code to return considering none of the causes of this code that I found online were addressed?

Thanks in advance

B1390 is for a reference voltage error. I would let the dealer do the re-flash and consider it fixed.
