P1670 Error Help Request

Just got the truck (2001 F350) back from the transmission shop (transmission rebuild) and I’ve had hard-ish starts and now a P1670 error code.

As background, I replaced my battery wires last year with welding wire and new lugs. I also installed a toggle switch in the cab to kill the IDM (see Springer Pop’s website).

Any thoughts on what might be throwing this code?

I have yet to verify the connections to the starter but I may start there.

Thanks!!

Nope. I’m wondering if my solder job to add the IDM toggle switch is failing.
