Technical All warning lights display and no instruments working

[paulxedos]

Hi,
My Fiat Bravo 1.9 JTD ( 57 plate) recently lost its instrumentation readings

By that I mean warning lights display on the dashboard (similar to pre-ignition to show that the warning lights are working) but when the engine starts all lights stay on and all clocks ( mileometer, petrol gauge, rev counter) display zero readings. In other words they do not move to show their true readings.

Externally everything works and drives as normal ( lights, indicators, brake lights, wipers) but nothing internally seems to work other than windows and heater. Radio, instrument readings, indicator sounds all currently fail

I've taken the car to a garage and they said they couldn't do anything due to fault code

VI7W NBC Node Absent

The garage said I would need to go to the main dealer to find out what it meant and what could be the problem

If anyone has any ideas that would be much appreciated

Cheers
Paul

Disconnect your battery for a few minutes, then reconnect. Hopefully then the computer will have untwisted its knickers.

I had the same issue when I had my grande punto . All warning lights on and the speedo and rev counted not moving. I took it to my local fiat dealer, he plugged his little computer into the car under the steering wheel and he said it had an error. He just deleted the error through the computer and was all fine after that. Didn't even charge me.

I have seen very similar symptoms on 2 grande puntos and it turned out it was a battery they were both 1.9 JTD

Dashboard not working... that would be a fuse on older vehicles, but not so shore on the Bravo with it's CAN network.
Still worth checking all the fuses.

Superb,thanks for all your answers. I've ended up cycling in to work today not trusting whether the car will make it but I'll have a go at untwisting its knickers with the battery disconnection when I get home.

Do note when you reconnect the battery and turn on the ignition it will complain about hillhold, esp etc etc not working. After a quick 2 min drive these will clear down. That is assuming the battery isn't faulty.

Those messages will disappear after you do the "Steering angle position learning" procedure ( turn steering all the way in both direction and then return to center)
turn off motor and then you should no longer have the hill older /asr/esp error

Ahhh, never knew that. I always just drove it 200 yards and they cleared.
