Many controllers that are fitted under the hood are pretty durable and can withstand moisture, but controllers fitted inside the cabin arent built to withstand moisture since they arent expected to get wet. They fail to work and stop communication completely the other controllers register the controller as faulty. Use the min-max voltmeter function to capture the max voltages and min voltages. If you need an inexpensive scanner that does the job, check out the Topdon vs. Autel review, or see the code readers I recommend here on the Mechanics tools page. Or check out the Code reader Amazon link below. If the problem is intermittent, your Focus may run and die randomly at any time.
