Read flash 29F400 for immo off.

U1600 is week signal from the key very common on fiats and alfas. Can be caused by anything from a bad earth to another key on the keyring causing interference.
Personaly i would check 1)the battery is healthy 2)check and clean the relay contacts under the bonnet 3)check and tighten the contacts in the plug to the code box 4)check all earths.
9 times out of ten it will be caused by one of the above

I read ECU with Galletto, three time to be sure. Please do immo off.
