Bench Calibration Harness Archivos

What is a Cummins Celect Plus bench harness used for?

A Cummins Celect Plus bench harness (also known as a Cummins ECM Jumper Harness or bypass breakout cable) lets you connect an N14 Plus or M11 Plus Celect Plus ECM directly on the bench. It connects to your bench calibration base on one end and to the ECM on the other, so you can verify communication, read fault codes, and bench test the module off the truck — without going through the vehicle dash connector.

When do I need a bench harness for my Celect Plus ECM?

A bench harness is useful when a Celect Plus engine shows signs of an ECM issue: a crank-but-no-start condition, no communication with your scan tool, intermittent or random shutdowns, hard starting when hot, or erratic idle. Connecting the ECM on the bench lets you power it up, verify communication, and test the module off the truck to confirm whether the ECM itself is the problem before reinstalling it.

Does this bench harness work for Celect and Celect Plus?

This harness is made for the Cummins Celect Plus ECM (N14 Plus and M11 Plus). The original Celect uses a different ECM connection, so it needs a different harness — we offer a separate Celect bench harness for that. If you are not sure which system your engine uses, contact us before ordering.
