CEL code 629 FMI 12

Got a code today 629 fm1 12-bad intel device controller 1 (lamps mil)

Looks like a communication issue, but I can not clear the code so it's legit.

Anyone experience this?

TIA

Update
Took it to a Spartan shop. The ECM needed a refresh/update. The problem was attributed to:

Cycling the battery switch when the ignition is in the accessory position; sort of makes sense.

Anyway all fixed and ready for our trip

I just got the same code 629-12 on our 05 Alfa
Just before leaving for our trip. My stop engine light started cycling on and off about every 30 seconds.
I'm thinking that I'm going to go the same route as well. I tried to start the engine with very low batteries and pretty cold temperature.
