Module or relay that controls FCW, LDW, TCS and more?

I took my wife's 2016 Odyssey, which gets about 15 miles of daily driving on her commute, on a roughly four hour round trip this weekend. Performed fine right up til the very second I pulled into the driveway. Then I got a solid engine light, followed seconds later by a FCW Failed warning and lights for LDW and TCS. It also began to idle rough. It throws codes P3400 and P0302, checked on two different OBD readers. After browsing the forums, I checked the oil. Level is normal on the dipstick and mileage has it at 30% oil life remaining. I also checked the battery. Battery manufacture date is 6/22 and it reads 12.5 cold and doesn't drop below 10.5 on startup. It goes up to 13.85 after startup. So, alternator seems fine. I can't imagine those sensors all go at the same moment independently and that I also lose a cylinder at that exact moment for separate reasons. So my question is whether there is a module or relay upstream of all those systems. If the answer's already on a thread, please give me the link. Thanks for your help.
