Choosing the Right ECU for Fiat Type 199
This engine control unit carries part number 51781569, ECU type MJD 6F3.P7 and reference 71600.019.04. The hardware version HW03P/2944-P748 shown on the label is also essential when selecting a compatible replacement.
Vehicle Compatibility
- Fiat Type 199 – selected versions identified on the ECU label as FIAT 199 1.3 SDE 75 HP.
Before ordering, compare part number 51781569, the complete ECU type MJD 6F3.P7 and hardware version HW03P/2944-P748 with your original engine control unit. Also check reference 71600.019.04. Engine displacement and power output alone are not sufficient to confirm compatibility.
Possible Symptoms of a Faulty ECU
- No communication with the ECU during diagnostic testing.
- Difficulty starting the engine or a complete no-start condition.
- No injector control signals.
These symptoms may also have other causes and do not, on their own, confirm an ECU failure.
ECU Preparation and Installation
This refurbished engine control unit is supplied in Virgin condition. Once a compatible unit is installed in a vehicle with a fully functioning immobiliser system, it automatically adapts to the vehicle and immobiliser. Under these conditions, manual immobiliser coding is not required.
