so my cable has arrived today,but not my solder iron so cant cancel the air bag today

anyway just wanted to know what software to use ?

do i need to have the car running to check diagnostics ? or can it be off ?

I haven't tried with my Punto, but with my VW Jetta 7 VAG, some settings / errors worked even with just the ignition turned on. With others you needed to have the engine on.
I would guess that the Punto is similar. Errors stored in the ECU should be available even with the engine off.

Key on but engine off

seem to be having a bit of trouble with this.cable came with no driver but on ebay page it says to install one of these heres the ebay page http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=120715195715&ssPageName=STRK:MEWNX:IT

also tryed to plug it in and where im sure it goes,theres a red wire on the end so it doesnt look like it will go in,im going to get a picture now so will be back in two sec's

EDIT:sorry for all the hassle but im a complete newbie to all this

so heres the picture,guessing it plugs into the black thing at the bottom left but theres a red wire coming out of there ??

give us a minute and ill run out and look at mine

edit: okay so im pretty sure its the socket just top the right of of the red lead and if yours is like mine on the other side of it is a blue one

so you mean that black thing with the purple lever thing on it ?

in your picture the cable with the red lever thing to the right of that below the fuse that has 7.5 on it its set back quite a bit

i think thats the one your after

thank you,found it,no wonder i could find it how far back it is

do you think need to install the driver for the cable ?

You need some sort of drivers which enables the usb cable to become a comm port.

Then when its given a comm port ie Comm12

You select comm12 on the program and it will connect to car

I use fiatecuscan and scanxl

Scanxl requires a diff cable tho.

Witch cabel did you get? as im after one for my punto mk1

Mk 1 is different cable to Mk 2

With Pins 1 3 and 7 i think it is
I was able to reset my airbags after they went out of voltage range (due to car battery been dead as a dodo)

The port is in the middle, on the very bottom of the fuse box

Good wiggle to get it in - otherwise i dont have a problem
*except Fiatecu dont know my ECU type*

On ebay there are cables with DIP switches built in for use on MK1 systems.

For Mk2 systems the simple cable with the three coloured adapters is the better bet. Yes, you pay £20 for the adapters but they are coded to match the functions.

Have you got a link for them? What protocol do they use OBDII or ELM327?

I really am no expert. This info was given to me by forrest159.

For most Fiats.

These allow access to abs and air bag.

ah i see now, it just saves you from having to modify your cable.

that elm 1 is pretty well priced. I have the obdII cable, but that just connects to engine and airbag ecu, so if you needed to do proxi alignment or connect to the power steering these would be ideal.

Yes and you wont get confused clicking the wrong switch. I don't know if that would be harmful but the adaptors avoid that risk.

The ones with the switch are KKL I believe used for the older ECUs.
