U1000 code So the other day my car kinda sputtered and cut out on the highway. So I went home and check for any codes even though no lights lit up on the dash. I got a U1000, a U1016, U1040 and a C0550 that were stored in the system. I'm thinking 1 led to the others. Anyone know what's going on? I checked connections and didn't see any corrosion on anything. Now today it must died in my garage after I was turning the parking lights off. And now it has a P0118 code for the coolant sensor. And I already replaced that sensor. But the U1016 code is gone. Any one have any direction I should be going? I'm thinking electrical?

Communication codes All the U codes are communication codes. If you lose communication on a module then it’s gonna pop a code. These codes could have been in the car before you had this problem. This problem can occur and most likely occurs when the battery gets low. God forbid a wire is pulling it down.
maybe I’m not understanding correctly but the car runs right and the car don’t die? If so clear codes and see if u-codes comes back. With a good battery. It’s gonna be difficult to have communication codes for brake module and abs codes at same time. I honestly feel like the battery has been weak or dead in past.
