Reset ECU?

[Luka]

Hi,
I have one question for Brava 1,6 16V '99.
Does anyone know, if i remove battery, for i don't know 24, 48 or more hours, and leave car without electricity, is it possible to reset ECU and delete all written errors codes?
I know the ECU have it's own, small battery, that he use when car stays without main power, but it also should be completely empty after some times also. Same thing is like in BIOS on computer and he reset himself after some times.

Is anyone try this?

Thank you

Yeah, 24hrs should do it. I think I've heard someone say that you will have to take it easy whilst driving for a few weeks as it gets used to your driving... uses up more petrol or something if you're driving hard all the time.

I might be talking complete bull mind you lol

Thanks but as it says " THIS WILL NOT RESET THE AIR BAG WARNING LIGHT", and that is problem with me.
I fixed some cables that make this problem with airbag, so i don't know how to reset warning light, i don't have diagnostic tool near me. So i thought if i disconnect the battery for a long period it will discharge battery for ECU and it will reset it!!

Nope, that won't do it. Needs to be resset by FIAT. Doesn't cost alot tho.

If you do a search on this forum, there's loads of stuff here about it.
