My traction control is turning off and ecu light is on , it only does this now and then , it still works when on. I have seen the solinoid post but just checking if it could be something else thanks .

I would disconnect battery, remove two plugs on solenoid cleaned them use some wd40 and blow off with compresed air, reconnect plugs and battery start car and have look if it comes on...I had similar problem here when i steamed cleaned engine..have go and hope it works...
