I have a 2015 570 touring ESP and the ESP light came on last weekend. It’s giving a error of 524086 4 which says voltage below normal, Or shorted to low source. I’ve checked the battery it at 12vdc with the key off and at 14.5 with the machine running. I’ve checked the fuse and the relay both are ok. I’ve done what I know to do any help would be greatly appreciated. The machine is not even a year old and only has 215 miles on it.
