Hi
I have a 2006 Fiat Panda 1.2 8v. Euro 4 model.
The ECU reference is Marelli IAW 4AF.S2/HW407/2088.
I would be grateful for any information regarding the pin layout & wire details.
 
Sorry for not making it clear.
I do mean the Engine Control Unit
 
This might help... It's for the 5AF, but I'd be amazed if the harness connections and pin-outs were different from the 4AF. Full Pin-Out descriptions towards the end of the document.

Thanks very much for your reply.
Unfortunately the pin layout is totally different for the 4AF.
The two connector blocks are not equal in size as per the 5AF.
 
The two connector blocks have 53 & 28 pins respectively.
 
I have now resolved the Engine ECM pin-out & cable colour identification outside of the forum.
There are in fact 6 no. different modules used for the 1.2 8v Panda 2003-2012
I now have the complete information for the following modules:
Magnetti-Mareli IAW 4AF
Magnetti-Mareli IAW 5AF - thank-you to the only member who replied
Magnetti-Mareli IAW 5NF
Magnetti-Mareli IAW 5SF8
 
hello,
i have a Panda 1.2. ECU is IAW.4AF.S2. Car is stuck, lock yellow icon is on.
One pin is broken, i suspect is related to CODE system. Does anybody have a pinout? male and female connector maybe? i'd like to wire the missing pin and trying to fix.
please help me

thank you

bother

I stumbled on this information accidentally last week but did make I note of where it was.

All ECU pinouts were included with some ECU reprogram software not sure if it was free or not.

I was looking for Suzuki diagnostic software at the time

and was looking at what the passthrough function was used for


its probably on this website somewhere but I am not a member https://www.autorepairmanuals.ws/arm/threads/database-pin-out-ecu-2015.35595/

Thanks for this I have problems undiagnosed as yet ( lambda I suspect -because it may have sooted up just starting it up- in and out of my garage during pandemic ) as waiting for reader to arrive but it has the IAW 4AF .SF/HW407/20BB-WRO MARELLI ECU which I am hoping is the same pin out. 59 1.1panda eco

its very rare for the ECU to fail


Its very common for the O2 sensors and wiring to fail along with evap and speed sensor on the same power wires.

I know where I would start. Error codes. ECU would be the last place I would check. With all the dangers associated with that.
 
Sorry for old thread...

I am also looking for the schematic for the :

IAW 4AF S2/HW407/20BB - WHM ECU. Anyone have it in their archives?

Thanking you!
