Cummins ISM code 145 is the DiagTechPro reference page for this Cummins diagnostic fault code 145 document, a 5-page PDF sourced from TruckFaultCodes.com (Copyright 2017) that covers the coolant temperature sensor circuit. The coolant temperature sensor is used by the ECM to monitor the temperature of the engine coolant. The coolant temperature is used by the ECM for the engine protection system, timing, and fueling control. When the condition is detected the ECM logs the fault and turns on the yellow warning lamp to alert the driver and technician.

This document applies to Cummins ISM CM570 (1999-02) / DTCs; ISX CM570 (1999-02) / DTCs; Signature CM570 (1999-02) / DTCs electronic engines used in on-highway and vocational trucks. The coolant temperature sensor is located in front of the turbocharger. The troubleshooting section walks through connector and pin inspection, engine-harness resistance measurements and pin-to-pin continuity checks, and ends with a road test that confirms the code is inactive and all fault codes are cleared. Because the same procedure isolates the sensor, the harness and the ECM in turn, it prevents replacing parts that are still good. Verify engine calibration and coverage against the official Cummins engine support site before ordering parts.
