Cornering lights circuit/fuse
Had check engine light codes related to O2 sensors that turned out to be a short in wiring harness rubbing on frame or something causing fuse 76 in E450 to blow. Service guy working on that now. He also says cornering lights are not working.

Anyone know what circuit/fuse this might be on?

I am hoping that wire might be in same harness with short.

Update: cornering light just loose bulb.

Note: wiring harness had to have a couple wires soldered and wrapped.
check engine codes were P0103, P0135, P0141, P0155

FIXED: Check Engine light codes P0103, P0135, P0141, P0155
P0103-Mass Air; P0135/P0141/P0155/P0443 O2 Sensors;

This is just a FYI if anyone else has same issue.

2015 Forest River Forester 3171ds -- E450 Ford.

Turned out there were 3 wires in wiring harness that were rubbed through at frame at EVAP Canister. This caused a short which burned out 20 amp mini-fuse 76.

RV technician soldered wires and and re-insulated to fix issue.
