Technical Proxi dashboard fail

[RBibegon]

I have a Fiat Bravo 1.4Tjet Dualogic 2009. All the menus have disappeared, I can't even set the time, the dashboard has stopped displaying which gear I am in. I'm trying to do a PROXI alignment, but it doesn't pass through the DASHBOARD. I check for errors, and the following codes come up: U1601 NCR Node Error, P2906, P0710. However, everything else works fine; it starts and switches gears.

Finally, after many years of dealing with this problem, I’ve solved it. Of course, I had already done everything mentioned above, but I knew the issue had to be something else. The wiring was perfect, the connectors were all excellent, all the grounds were cleaned, and I even added extra grounds from the battery to the engine and separately to the chassis.

In the end, I started clearing all the errors through OBD, and as always, one error remained — U1601. But it still allowed me to do the proxy alignment, and it completed successfully. However, the odometer kept flashing, and the gear indicator wasn’t showing on the dashboard.

Then I decided to clear the ABS errors, and for that Multiecuscan asked for the green adapter. I connected it, started deleting all the errors, and everything got cleared. Suddenly the gear display appeared, and everything started working exactly as it should.

Who knows how and why… but whatever, the important thing is that it’s all behind me now.
