Front FDU replacement (resolved)

[Baja_bronco]

After replacing my front FDU dash looks like a Christmas tree and locker won’t engage. When swapping out to a new one does it need to married to the vehicle?

Did you recheck all of your connections?

No. There's no actual electronic connection to the FDU (other than the locker or FAD, and W/T's don't have a FAD). It's a happily dumb piece of hardware.

Odds are you jacked up a wheel speed sensor - I'd go check those out.

Also - check DTC codes - it will probably point you in exactly the right direction.

Did you also change the ratios?

P160A fault will do all that! Let us know the codes.

Thank you for the help.

Did you recheck all of your connections?

yes thoroughly. Gonna start with the wheel sensor like Brian suggested.

It’s just a stock replacement from Ford. I ordered both front wheel speed sensors. We’ll see if that helps.

Keep us posted if this is the fix.

Update!!! Driver side speed sensor was bad. Changed both just because and everything cleared.
