I went for a long ride I came back washed it and went to start it few days later and had a code 0 520207 with a 4 under it I read that a short too ground? I have 12.5 volts power going to the connector and switch but 2.5 volts when i check ground so I’m assuming I have a bad ground. Fuses are good I swapped relays also. Anyone have ground wire issues I believe it’s the gray wire to awd control circuit and gray to the switch too. Thanks
