KEY FEATURES
IMPORTANT NOTES
Applications and functionality
The JDCM2250 is a connection cable: It connects the Cummins ECM CM2250 directly to your diagnostic interface, independently of the vehicle wiring. The functions you then perform are part of Jaltest Central Services and run through the ATS team.
What the cable assembly is for
- Connection to the control unit: The 60-pin connector attaches to the Cummins ECM CM2250.
- Connection to the interface: The 16-pin OBD2-side connects to the Jaltest Link.
- Support tool for Central Services: The ATS department may require you to have such a cable.
- One cable per assembly: This configuration is specific to the CM2250; a different ECM type requires a different isolation cable assembly.
What Jaltest Central Services offers for Cummins
- Remote diagnostics: Jaltest technicians perform functions that are not possible with a standard diagnostic tool, such as reprogramming certain control units.
- Cummins calibration update (70810000): The service Jaltest provides for Cummins; this requires a minimum software version 24.1 required.
- Payment per use: You purchase a service on a case-by-case basis and settle using credits; for Cummins, that is reference 71101082.
- Jaltest Link V7 or later: With an older interface version, you cannot access Central Services.
- Via the ATS team: They will advise during your request whether a service is available for your control unit.

|---|---|---|
| JDCM850 | Cummins ECM CM850 | 4+50-pin |
| JDCM2150 | Cummins ECM CM2150 | 4+60-pin, two loose connectors |
| JDCM2250 | Cummins ECM CM2250 | 60-pin, one connector |
| JDCM2350/2450 | Cummins ECM CM2350 and CM2450 | 96-pin, one connector with red lever lock |

Compatibility
The ECM type is what matters, not the engine series or vehicle manufacturer.This cable harness is designed for the Cummins ECM CM2250 with the 60-pins connector. With these isolation cable harnesses, no engine or vehicle coverage is specified: there is no list of engine series or vehicle makes to check whether the cable harness will work in your situation. What counts is the control unit nameplate and the number of pins on the connector.
- What does matter: The ECM type (Cummins ECM CM2250) and the number of pins on the ECM connector (60-pins).
- What does not matter: The engine series, vehicle manufacturer and year of manufacture; these are not specified for this cable harness.
- Check yourself: Read the control unit type from the nameplate and count the pins on the connector.
- Recognisable by the connector: If there is a separate 4-pins connector alongside the 60-pins main block, you need the JDCM2150.
