Is this the only item acting strange in your car? Was any work done on the car before this problem occurred?

2015 is newer than my newest shop manual. The problem could be anywhere in the circuit.

Do you have a scanner that can read codes other than the check engine light codes?

You may want to stop at a parts store to see if their scanner can read vehicle-specific codes. You may want them to test your battery and alternator while you are there, because low voltage from the battery can cause strange issues.

Was anything done to the car prior. Does your high beams work. If not check fuse 12 under the hood should be a 30. You need to have your alternator checked and power/ground cables. You have a voltage issue somewhere

I misread your first post about the fuses. The next step is to figure out what supplies power to the fuses that are missing power.

SeanJordan - is the 30 amp fuse 12 the 12V source for the non-powered fuses?

Seanjordan20 Jan 18, 2020 11:40 PM

It's hazy. I looked and it had 7 things on that fuse one of them being a fuse box. It wasn't clear so thats why I suggested it. It has to either be a fuse in the engine compartment or an electrical issue effecting the hole system (a power harness) but the harnesses rarely have issues unless there is something leaking or previous work done. I don't know what region the car sits so can't say rust

This is what in seeing on 12

Seanjordan20 Jan 18, 2020 11:57 PM

This was a good read. Being that certain things aren't working it seems like the MICU is in a fail safe mode meaning it detected getting less than 10v at some point. The read is from a Honda Fit should be the same across the board

MICU

I live Florida. Nice car has Zero corrosion. I did plug in 2006 trunk latch to trouble shoot. a trunk light Light . it lite up then unplugged and these issues started. i have a spare fuss box with a micu i will install and see if the issue clears.do not look like fun job. Then deal with the immobilizer.
