Before purchasing, compare all numbers shown on the label of the original control unit. The vehicle model, engine capacity or appearance of the housing alone does not confirm full compatibility. The 51788361 part number, IAW 5NF.S5 designation and HW104/3004-A4W hardware version should match the control unit originally fitted to the vehicle.
VIRGIN – Plug & Play without cloning
The control unit has been cleared of data from the previous vehicle and prepared in VIRGIN condition. After installation in a compatible Fiat Panda, the module automatically synchronises with the Fiat CODE system and stores the new vehicle’s data. There is no need to send the original ECU for cloning or copy the immobiliser data.
Correct installation requires matching part numbers and a fully functional immobiliser, Body Computer, key and vehicle electrical system. After the first pairing procedure, the control unit becomes assigned to the vehicle.
Possible symptoms of a faulty IAW 5NF.S5 ECU
- the engine does not start even though the starter motor operates correctly,
- the vehicle stalls or intermittently loses communication with the control unit,
- no control of the ignition coils or fuel injectors,

Frequently asked questions – FAQ
Does the 51788361 control unit fit a Fiat Panda II 1.2 8V 60 HP?
The 51788361 control unit is used in selected Fiat Panda II 169 versions with the 1.2 8V 60 HP engine, code 188A4.000. Before purchasing, also compare the IAW 5NF.S5, 61600.579.04 and HW104/3004-A4W references.
Does the 61600.579.04 ECU for Fiat Panda require programming?
No. The offered 61600.579.04 control unit has been prepared as VIRGIN and automatically synchronises with the vehicle’s immobiliser after installation. It does not require cloning of the original ECU or additional programming beyond the standard first-start procedure.
Does the IAW 5NF.S5 HW104 fit a Fiat Panda 1.2 Dualogic?
Yes. The IAW 5NF.S5 HW104 control unit was used, among others, in the Fiat Panda 1.2 with the Dualogic or AMT automated manual transmission. However, compatibility of the Fiat 51788361 part number and the 3004-A4W software version must be confirmed.
