Cummins fault code 289 troubleshooting summary
A relay installed between the ECM and the OEM vehicle accessories lets the engine automatically shut down all vehicle accessories whenever an idle shutdown occurs. The location of that relay is dependent on the OEM, so the chart refers the technician to the OEM Troubleshooting and Repair Manual for the exact position. The document then works through labelled steps that disconnect the OEM harness from the actuator harness, flush and inspect the connector pins, and verify the fault code is inactive after the repair.
Referenced Cummins service items include electronic contact cleaner, Part Number 3824510. Each pin inspection and resistance measurement is paired with a pass or fail branch so the harness or relay is repaired only when the reading confirms the fault.
Applicable truck models
This procedure applies to Cummins M11 M11 CELECT Plus (1995-98) engines as fitted to Class 8 highway trucks, together with the OEM accessory wiring installed by the truck builder. Always confirm the engine dataplate and the OEM manual before servicing. Full engine data and dealer support are available on the Cummins official website.
Who needs this Cummins fault code 289 manual
Heavy-duty diesel technicians, fleet service managers and independent workshop owners diagnosing an idle shutdown accessory problem rely on this manufacturer procedure instead of guessing at the relay or wiring. Because the driver is shared between the ECM and OEM equipment, the chart keeps engine-side and body-side checks in the correct order.
