hi, guys, I had a power steering failure the battery is new and very good condition I replaced the whole steering column now its working fine but the warning light is still on dashboard screen says power steering failure and airbag failure please help
the car didn't pass the inspection and I can't use it

The other power steering thread suggests that there is an ECU on the steering motor, so if your steering ECU is now no longer the original one, then a proxy alignment will be required (so steering ECU can communicate with the main ECU).

The airbag has an ECU too, and I suppose that also doesn't recognise the steering ECU now, so the same thing applies.

For a proxy alignment you need to have the software and leads to connect to the car's diagnostics port. A fiat dealer will have one for sure but some other specialists might have a similar system that can do a proxy alignment on a Stilo. You might need to ask.

If you have a laptop and like poking around with electronics then you can buy the software and the correct lead so that you have it for any other time you need to check the ECU codes or align something.

When i had an electrical fault (check vehicle protection)on my Stilo 1.4,i bought an entire set....ECU,body computer,lock set and clocks.
When i eventually fixed it (was a broken Canbus wire) i put all the replacement stuff on the car to make sure it all worked ok.
It did,the steering(and airbag and ABS) was the original and worked fine on the replacement ECU and body computer,without needing any further allignment.

It might still be worth having a look on the proxy alignment doodah. That might at least explain why it thinks there's an issue.
