Delphi DCM3.5 engine ECU, part numbers 28278423 and AG91-12A650-ZG, for selected Ford S-Max 2.0 TDCi models. Supplied ready for programming and mandatory PATS adaptation, with a 6-month warranty.
Original Delphi DCM3.5 engine control unit designed for selected Ford vehicles equipped with the 2.0 TDCi engine. The module carries Delphi part number 28278423 and Ford reference AG91-12A650-ZG, also written without hyphens as AG9112A650ZG.
The same ECU type may be used with different software and equipment configurations. Before purchasing, compare the full reference AG91-12A650-ZG and Delphi number 28278423 with the label on the original module. We also recommend providing the vehicle VIN.
Similar symptoms can also be caused by wiring faults, power supply or ground problems, sensors or the fuel system. A complete vehicle diagnosis should therefore be carried out before replacing the engine ECU.
The ECU is supplied as a module ready for programming. It will not start the vehicle automatically after installation – it requires programming with suitable software and adaptation of the PATS immobiliser system.
The adaptation can be performed using suitable diagnostic equipment that supports the specific vehicle, for example Ford IDS or FORScan, provided the required service functions are available for that particular version.
If the original ECU still communicates and a complete data read is possible, we can also perform a 1:1 clone. The original module is required for this service. Cloning availability depends on the condition of the memory and processor in the damaged ECU.
Is ECU 28278423 compatible with every Ford S-Max 2.0 TDCi?No. This module is used only in selected engine and software versions. Part numbers 28278423 and AG91-12A650-ZG must be compared with the original ECU. |
Is ECU AG91-12A650-ZG Plug & Play?No. The ECU is ready for programming, but after installation it requires vehicle-specific configuration and mandatory PATS immobiliser adaptation. |
How do you program a Delphi DCM3.5 ECU in a Ford S-Max?The correct software and configuration must be programmed first, followed by PATS initialisation or synchronisation. Ford IDS or FORScan can be used if the required functions are supported for the vehicle. |
Can ECU AG9112A650ZG be cloned from the original module?Yes, provided the complete and undamaged data can still be read from the original ECU. The original module must be sent to us for a 1:1 cloning service. |
Do the keys need to be coded after replacing the ECU in a Ford S-Max 2.0 TDCi?The ECU always requires synchronisation with the PATS system. Reprogramming the keys may be necessary depending on the procedure used, the vehicle configuration and the immobiliser data already stored. |
