I have a 2012 Ram 1500 and the cruise control stopped working. I get two codes PO591 and PO585. What will repair this?

Are you thinking you'd like to get this inspected by the dealer? Send us a direct message with your VIN if you need any assistance with that process.

Could be a bad multifunction switch. Do a google search of P0585 and another of P0591 and you will get a lot of information. The P0585 shows the cruise control module noted a discrepancy with some voltages. A search will get you a lot of info.
