#13 of 13 RFA 1 Low Battery by threadguy

Dec 04, 2011 (7:52 am)

I've been driving an '03 GMC Sierra 1500HD, 6.0L since 2006, bought it used w/ 45K mi. and have had NO problems w/ it other than normal maintenance. The speedometer is gone but the odometer's still rolling, just turned 129K. The message center is indicating "RFA 1 low battery". I've searched only on-line and can't find what this means. The battery was replaced a month ago. Everything is running fine...for now. I had an issue w/ the oil pressure gauge this weekend. The needle was all the way to the right. It's working fine now, all fluids are fine too. Just curious if I'm headed for any surprises. Just want peace of mind, this is my one and only vehicle other than my wife's street legal golf cart! Is there anyone that can coach me on whether or not I have any potential issues?
