Jaltest Cummins Revision + JDCM2150 — CM2150 ECM Insulation Harness

This is the Cummins CM2150 ECM insulation harness required to perform the Jaltest Cummins Revision Update (Central Services action) on engines running the CM2150 control module. The CM2150 is the Cummins ECM used on ISX15, ISX12, and ISB engines in the 2010–2013 EPA tier (EPA10 / GHG11 through early GHG14 transitions). Many heavy-duty shops have a significant number of these units in regular service — the CM2150 covers a large portion of the 2010–2013 model year Class 8 fleet that is now deep in independent shop territory.

Jaltest Central Services: Cummins Revision Update

The Jaltest Cummins Revision Update is a Central Services action — a remote, assisted ECM recalibration carried out by Cojali USA's ASE-certified diesel technicians with you connected and the vehicle in the bay. The technician uses Jaltest Diagnostics software to write an updated calibration file directly to the Cummins ECM, addressing factory-released software revisions that can resolve fault codes, improve fuel economy, correct driveability concerns, and restore proper aftertreatment function.

To perform this action, you need two things: an active Jaltest license and the correct insulation harness cable for your specific Cummins ECM family. The cables below are the required harnesses — they provide the proper electrical isolation between the Jaltest interface and the ECM during the programming event, protecting both the ECM and the diagnostic tool.

Central Services Process

• Verify initial conditions in Jaltest Diagnostics software
• Request the Cummins Revision Update through your distributor or Cojali USA directly
• Payment processed (Central Service action: 50)
• Schedule a time — Cojali USA technician connects remotely and carries out the revision
• Your ECM receives the latest factory calibration; faults are cleared

Important: Each cable below includes one FREE Cummins Central Services action as part of the Jaltest Central Services Cables Promotion. The 85 cable price effectively bundles the cable and your first revision action together, making the cable itself nearly cost-neutral for a shop that intends to perform even one Cummins revision.
