2000 dodge ram 3500 dually w/ 5.9 cummins. I changed the batterys, and when I started and it ran fine with no check engine lights. When I stopped the truck , I heard a humming noise under the hood. It is the abs pump. I unplugged it to stop it. I now have the abs and a check engine light on Can I drive it like this? What do I check for? Thanks much
