Hi. And welcome to FF
What age is the car..?

Depending where you are based. It MAY be better for a repair.

What issue highlighted its failure..?
Charlie

Thanks
Fiat Doblo 1.6 16V - made in Vietnam - year 2006,
Fault : check engine light on, key code light on, not ignition spark.
(sorry because my English not good)
Look forward to further guidance

Hi,
the KEY CODE = is the engine immobiliser

it will stop the engine spark - may also stop the fuel pump in fuel tank - rear of doblo..

the engine light may be different.

I would try this;

the connection from battery Negative (-) terminal,
to the Doblo BODY structure
to the ENGINE / GEARBOX

it is possible to temporarily fit an EXTRA / additional
earth / ground cable in a similar position.

I checked all wire in ECU. V+, mass ( V-)... connection with ECU. It 's good.
I tried replacing the other ECU ( from another Doblo) on the car , the car works well.
So perhaps ECU has damaged an I think the need to replace it with a new ECU
What else can I do ?

So..you used a subsutute ECU..and it was good.
Then refitted the original.and it was DEAD again..

Google the ECU code number..find what other vehicles use that series

I see many ECU on Google, but it not same code number. Ex : IAW 5NF.T1 , IAW 5NF.T2 , IAW 5NF.T9... but not IAW 5NF.T4
Does this kind of substitute for T4 ? and it must decode immobilizer (key code).
