Files & tools
What is a Cummins ECFG file?A Cummins ECFG is the XML definition Calterm needs to read a calibration: each parameter's name, address, type and scaling. What it is, how to pick one.ECFG vs E2M: which Cummins definition file do you need?E2M is the older text-format Cummins definition (Celect, CM550, CM570); ECFG is the XML format for CM850 to CM3230. How to tell them apart.What is an .xcal file? The Cummins Calterm calibration explainedAn .xcal is the Cummins calibration file Calterm reads from and writes to an ECM: a CRC, an XML header and Intel HEX data. What it holds and how to use it.Cummins Calterm explainedCummins Calterm is the engineering tool that reads and writes .xcal calibrations using an ECFG. What it does, what it needs, how it differs from INSITE.Cummins INSITE explainedCummins INSITE is the dealer and fleet service tool: fault codes, live data, tests, feature adjustment and ECM calibration downloads. Levels and limits.INSITE vs Calterm: which Cummins tool do you need?INSITE is the Cummins service tool; Calterm is the engineering calibration tool. Side by side: fault codes, tests, parameters, .xcal, ECFG and licences.
ECMs & identification
Cummins ECM generations: CM570 to CM3230Every Cummins ECM family from Celect and CM570 to CM2350, CM2450, CM2670, CM2880 and CM3230: engines, years, emissions level, memory layout and ECFG files.How to find your Cummins product id and software versionWhere to read the Cummins product id (BKR, BDC, BGT) and software version (64.60.21.5): the .xcal header, Calterm, INSITE's ECM code and the dataplate.Cummins ESN, VIN and the ECM dataplate: what the calibration knows about the engineHow the Cummins ECM stores the ESN, VIN, CPL and ECM code, where INSITE and Calterm show them, and why they matter for programming, ECM swaps and files.
Fault codes & diagnostics
SPN and FMI explained: how Cummins fault codes are builtWhat SPN and FMI mean on a Cummins fault code, the full FMI table, how Cummins FC numbers, J1939 SPN/FMI and OBD P-codes relate, and how to read DM1.Cummins fault code lamps: red, amber, MIL and the aftertreatment lampsWhat each Cummins warning lamp means: red stop, amber check engine, maintenance, MIL, DPF, HEST, DEF level and blink codes, with the lamp each code sets.Cummins derates and inducement: what triggers 25 percent torque, 5 mph and shutdownWhy a Cummins drops to 25% torque or 5 mph: engine protection, soot derates and SCR/DEF inducement stages, and the fault codes that flag them.Common fault codes on the Cummins ISX15 and X15 (CM2250, CM2350, CM2450)The fault codes that keep coming up on Cummins ISX15 and X15 (CM2250, CM2350, CM2450): DPF, SCR, NOx, VGT, EGR, derate and ECM codes with SPN and FMI.Common fault codes on the Ram 6.7 Cummins (ISB 6.7, CM2100 to CM2450B)The codes Ram 2500, 3500 and cab-chassis 6.7 Cummins owners see most: P0401, P0404, P2262, P20EE, P229F, P2463, P2BA7, P0088, with Cummins FC numbers.J1939 basics for Cummins enginesJ1939 essentials for Cummins-powered trucks: the 9-pin connector, 250 vs 500 kbit/s, PGNs and SPNs, DM1 / DM2 fault messages and RP1210 adapters.
Emission systems
Cummins DPF, DOC and regeneration explainedHow the Cummins DOC and DPF work: passive, active and parked regen, HC dosing, soot load stages, sensors and fault codes 1921, 1922, 2639, 3168, 1993.The Cummins EGR system explainedHow Cummins cooled EGR works on ISX, X15, ISB and L9: valve, cooler, delta-pressure and temperature sensors, flow control and codes 2272, 2357, 3382, 3383.Cummins SCR, DEF and NOx sensors explainedHow the Cummins SCR system works: DEF dosing, SCR catalyst, intake and outlet NOx sensors, efficiency monitoring and codes 3582, 1694, 3749, 3547, 3568.The Cummins VGT turbo and actuator explainedHow the Holset VGT on Cummins ISX, X15, ISB 6.7 and L9 works, what the actuator does, calibration and failure modes, and codes 2387, 2449, 2634, 2636.
