Choosing the Right ECU for Your Lancia Ypsilon
This unit is identified by part number 51806503, ECU type MJD 6F3.Y2 and reference 71600.073.01. The complete identification details on the label distinguish it from other engine control units in the MJD 6F3 family.
Vehicle Compatibility
- Lancia Ypsilon – selected versions identified on the ECU label as YPSILON 75HP SDE EU4 UEGO.
Before ordering, compare part number 51806503, ECU type MJD 6F3.Y2 and hardware reference HW03T/3454-Y266 with your original unit. Also check references 71600.073.01 and 6LE-BAV5J. The vehicle model and 75 HP engine rating alone are not sufficient to confirm compatibility.
Possible Symptoms of a Faulty ECU
- No injector control, even after other components of the injection system have been checked.
- No communication with the engine control unit during diagnostic testing.
- Signs of water ingress on the ECU housing, connectors or inside the original unit.
None of these symptoms alone confirms an ECU failure. If the original unit has suffered water damage, identify and eliminate the source of water ingress and inspect the electrical connectors before installing a replacement.
ECU Preparation and Installation
This refurbished engine control unit is supplied in Virgin condition. Once installed in a compatible vehicle with a fully functioning immobiliser system, it adapts automatically to the vehicle. This listing is for the Virgin version only; ECU cloning and IMMO OFF services are not included.
