FIAT 500 cambelt change - phonic reset

Hello everyone!

I'm scheduled to change the cambelt (and everything else) on my mums cambelt in a couple of weeks. I've got all parts to change it - including the locking tools - but I've got a question about the phonic wheel resetting.

According to the guides I've seen you need to reset it when the cambelt is swapped so the ECU can then relearn the settings (minute differences in belt tension). Now, lots of places say you need the FIAT Multiscan software and other are saying all you need to do it start it up and leave it running on idle then rev to 5k for 10 seconds then idle and repeating it should reset things.

So, a couple of questions really.
- All the guides are shown from puntos. Engine is the same but I haven't had it confirmed that the 500 is exactly the same.
- Does the rev method work?
- If not then is multiscan easy to use? I have a few diagnostic tools already: will any of them work? Full blown VCDS Hex/Can/USB (VAGCom), Gendan ODB GCR25 and a cheapo ebay special KKL 409.1 usb line (that can be used for free versions of VCDS).

Thanks for the help
Chris

Engine is a 1.2 8v by the way

Never had any issues with this personally when doing belts .

Thats good to know JBT, thanks.

Dead easy job.

Very prone to water pump leaks so might be worth getting one prior to stripping it.
Give me a buzz if you struggle when doing it.

Cheers. Got all the kit already, belts, tensioners, aux stuff, waterpump and thermostat too (might aswell whilst the coolant is out)
