ECU 55193433 for Fiat Panda 169 1.2 8V – Virgin plug & play

We offer an original, used and thoroughly tested Magneti Marelli 55193433 engine control unit for selected versions of the Fiat Panda II 169 1.2 8V. The module carries the references IAW 5NF.S5, 61600.579.02, HW104/3003-A4T, C146 and 4CCNH8K1E.

The offered engine control unit has been tested, prepared for installation and is covered by a warranty. It is supplied in Virgin plug & play condition. Data from the previous vehicle has been removed, and after correct installation the ECU automatically pairs with the vehicle immobiliser system.

Applications of the 55193433 61600.579.02 ECU

The 55193433 IAW 5NF.S5 engine control unit is mainly found in the second-generation Fiat Panda, type 169, fitted with the 1.2 8V FIRE petrol engine. This module is most commonly used in vehicles from the early production years, including selected versions with four-wheel drive or an automated transmission.

  • Fiat Panda II 169
  • 1.2 8V FIRE petrol engine
  • engine capacity: 1242 cm³
  • power output: usually 44 kW / 60 hp
  • engine code: 188A4.000
  • most common model years: 2003–2005

Several different Magneti Marelli engine control unit versions were used in the Fiat Panda 1.2. The vehicle model, engine capacity or year of manufacture alone are not sufficient to identify the correct ECU. Before purchasing, compare all references shown on the label of the original module.

Control unit numbers shown on the label

  • 55193433 – Fiat part number
  • 61600.579.02 – Magneti Marelli number
  • 6160057902 – number written without dots
  • IAW 5NF.S5 – engine control unit type
  • IAW5NF.S5 and IAW5NFS5 – alternative forms of the reference
  • HW104 – hardware version
  • 3003-A4T – software version
  • C146 – ECU variant designation
  • 4CCNH8K1E – additional identification number

The safest way to select the correct part is to match both the 55193433 and 61600.579.02 numbers. IAW 5NF.S5 control units with a different Fiat part number or software version should not be considered direct replacements without prior verification.

Virgin plug & play – how does the ECU work?

The Fiat Panda 55193433 Virgin ECU does not contain the immobiliser code from the previous vehicle. After installation and the first ignition cycle, the ECU retrieves the security data from the Fiat CODE system and stores it in its memory.

Common symptoms of a faulty IAW 5NF.S5 engine control unit

  • the engine does not start even though the starter motor operates correctly,
  • the vehicle stalls after the engine or control unit has warmed up,
  • there is no diagnostic communication with the ECU,
  • the ignition coils or fuel injectors are not being controlled,
  • the engine runs unevenly and recurring misfires occur,
  • there are problems with throttle body or accelerator pedal control,
  • the engine warning light or immobiliser warning light comes on,
  • internal EEPROM memory or processor faults are stored.

Similar symptoms may also be caused by damaged wiring, poor ground connections, incorrect power supply, ignition coils, fuel injectors, the throttle body or sensors. A complete vehicle diagnosis should be carried out before replacing the ECU.

FAQ about the Fiat Panda 55193433 IAW 5NF.S5 ECU

Is the 55193433 ECU suitable for a Fiat Panda 1.2 8V?

Yes. Part number 55193433 is used in selected versions of the Fiat Panda II 169 with the 1.2 8V petrol engine. Before purchasing, also compare the 61600.579.02, IAW 5NF.S5, HW104 and 3003-A4T references.


Does the 61600.579.02 ECU program itself in a Fiat Panda?

Yes. The offered 61600.579.02 engine control unit has been prepared in Virgin plug & play condition. After installation, it automatically pairs with the vehicle immobiliser and does not require cloning of the original module.


Is the IAW 5NF.S5 HW104 ECU compatible with the 188A4.000 engine?

The IAW 5NF.S5 HW104 engine control unit is used in selected Fiat Panda 169 vehicles with the 1.2 8V FIRE engine code 188A4.000. Final compatibility must be confirmed using the complete numbers shown on the original ECU.


Does the Fiat Panda 55193433 ECU require coding?

The 55193433 Virgin version does not normally require manual immobiliser programming. After installation, the module retrieves the security code from the vehicle. It may only be necessary to clear stored fault codes or perform a phonic wheel adaptation.


Are the 55193433 and other IAW5NFS5 control units interchangeable?

Not always. The IAW5NFS5 designation alone does not guarantee compatibility. The Fiat part number, Magneti Marelli number, hardware version, software and vehicle configuration must be checked. The safest solution is to use a control unit with identical references.
