Ford number and Delphi number
Both numbers on the label matter when you order:
- Ford number: AV41-12A650-CG / AV4112A650CG
- Delphi number: 28291697
- ECU type: Delphi DCM3.5
Typical symptoms of a faulty DCM3.5 ECU
A damaged ECU can stop the engine from starting because the injectors receive no signal. The tester then cannot connect to the unit, and a measurement may show no power at the ECU despite good fuses. The failure can follow water ingress or a short circuit in the wiring.
The same symptoms can, however, come from a fault in the harness, power supply or sensors, so run a diagnosis before you buy an ECU.
Does this ECU fit your car?
Model and year are not enough, because the same number AV41-12A650-CG may have been fitted to several Ford models. Look at the label of your ECU and check that it shows AV41-12A650-CG and 28291697. Not sure? Send us a photo of the sticker and we will check it before you buy.
