Cummins ISM code 115 is the DiagTechPro reference page for this Cummins diagnostic fault code 115 document, a 6-page PDF sourced from TruckFaultCodes.com (Copyright 2017) that covers the camshaft engine position sensor circuit. The camshaft engine position sensor provides engine speed and position information to the electronic control module (ECM). The sensor must be powered up by (+) 5 VDC to operate. The sensor generates the signal from an extra lobe on the camshaft. When the condition is detected the ECM logs the fault and turns on the red 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 camshaft engine position sensor is located on the intake side of the engine block on the cylinder head to the right of the ECM. 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.
