Cummins ISM code 482 is the DiagTechPro reference page for this Cummins diagnostic fault code 482 document, a 8-page PDF sourced from TruckFaultCodes.com (Copyright 2017) covering the lamp: amber fuel pressure low – data valid but below normal operational range – moderately severe level condition. The gear pump draws fuel from the fuel tank through a suction fuel filter and an anti-drainback valve. The gear pump develops between 1724 and 2620 kPa [250 and 380 psi] of fuel pressure. When the condition is detected the ECM logs the fault and illuminates the amber warning lamp.

Applicable truck models
This document applies to Cummins Fuel System Circuit electronic engines in the ISM CM871 (2007-09) family used in on-highway and vocational trucks. The fuel pressure is monitored by the ECM. If the rail fuel pressure is lower than an acceptable level for a given set of engine operating conditions, the fault code is logged. The troubleshooting section walks through connector and pin inspection, circuit measurements and step-by-step checks, then confirms code 482 is inactive before all fault codes are cleared. Verify engine calibration and coverage against the official Cummins engine support site before ordering parts.
