Jeep Compass 2019 (check engine light)

Check engine light is on dashboard. I coded it and it came back as a P103B (generic). Any help on what it could be? Alternator is new, battery is new, wires to starter are new and fuses are fine too.

3 year old Jeep… Maybe still under warranty?

That is what the code means.

It is a “Fiat Thing”… NO one understands!
