The Jaltest JDCM2150 is the isolation cable harness for the Cummins ECM CM2150. On the engine side, the cable ends in two separate connectors: a black 60-pin Deutsch connector with two blocks of thirty contacts and a central fixing bolt, and alongside it a small grey 4-pin Deutsch connector with an orange lock. Together these form the 4+60-pin from the title. On the other end is a black plastic housing with the 16-pin OBD2 connector and the marking JDCM 2150.
The cable harness is a physical component that we send to you and belongs to Jaltest Central Services: a pay-per-use service in which Jaltest technicians carry out functions remotely that are not possible with a universal diagnostic device, such as reprogramming certain control units. For Cummins this is the Cummins calibration update (70810000), which requires a minimum of software version 24.1. The ATS department may require you to have such a cable harness. Your Jaltest Link must be V7 or newer; you pay for the services with credits (71101082).
ADVANTAGES
POINTS TO NOTE
Applications and features
The JDCM2150 is a connecting piece: it connects the Cummins ECM CM2150 directly to your diagnostic interface, separately from the vehicle wiring. What you then have carried out belongs to Jaltest Central Services and is handled via the ATS team.
Control units you can access
- ECM CM2150: Engine control, 4+60-pin.
What you can do
- Calibration update: Cummins (70810000).

- Request a service: Via the Jaltest ATS team.
- Connecting: 60-pin and 4-pin connector to the ECM.
- Connecting the Link: OBD2 side to the Jaltest Link V7 or newer.

Compatible control units and applications
The ECM type is decisive, not the engine series and not the vehicle make. This cable harness is made for the Cummins ECM CM2150 with the 4+60-pin connection. For these isolation cable harnesses no engine or vehicle coverage has been specified; the nameplate of the control unit and the number of pins on the connector are what counts.
Cummins:
- ECM CM2150: 4+60-pin connection.
How to establish this:
- Decisive: The ECM type (Cummins ECM CM2150) and the number of pins on the ECM connector (4+60-pin).
- Not decisive: The engine series, the vehicle make and the year of manufacture; nothing has been specified for these cable harnesses on this point.
- Recognisable by the connector: If there is a separate 4-pin connection alongside the 60-pin main block, this is the correct version; if it is missing, you need the JDCM2250.
The Cummins range at a glance
The range comprises five isolation cable harnesses. They differ in the number of pins, the number of separate connectors on the engine side and the length of the cable. The version on this page is shown in bold.
