Fiat Grande Punto 1.3 75hp error U1706

[Rebound]

hi all!
Are two days that I fight against this problem...
describe briefly the problem:
the car comes with the ecu tampered with, I can start the bike by fixing the ecu and doing the partial...
can I encode the injectors and forth without problems, except for the battery completely to the ground.
Change the battery in and out the problems...I have no idea what they have done.
diagnosis errors are the following

Ecu engine:
U1706 Can Network (NCM-NFR)

Body Computer:
U1701 Ncm
B1053 NCM inertial Switch
U1715 Node Yaw
U1706 Brake System
U1702 electric Steering (NGE)
U0019 Line B-Can

Framework tools:
U1019 Can Cable
U1700 Central Computer
U1701Ncm
U1706 Node Brake

In the framework remain flicked the lights on: ABS,ESP, Brake and anti-skid
Power steering does not work
I tried to rialineare all the ecu but nothing to do
Checked all fuses all ok...
to someone ? gi? experienced something similar?

thank you for your attention!

I fully agree, these tests you could do on the 127, but not even enough to have a tester....!! however, check the power supply and the masses on the ABS, and check the CAN Line from the ODB.

Sorry, OBD.
