So my check engine light, VSC light and 4x4 light all came on at the same time. I changed the gas cap and the lights went on, a week later all the lights are now back on. I'm trying to figure out what is wrong and causing this.
Do you

Hello,

It sounds like you have a main relay that is going out IGN2, IGN1 or power relay that is out, Here is a power distribution wiring diagram so you can see what I am talking about. It must be one of these becasue some many system are affected.

Here is a guide to help confirm the failure.
