Cummins ISB Electronic Diagnostic Manual CM2250

Cummins ISB Electronic Diagnostic Manual (CM2250)

Cummins ISB Fault Code Manual (CM2250)  Also covers ISC, ISL & ISX with CM2250

This is the factory printed Cummins ISB Fault Code Manual (CM2250). This manual also includes the same electronic diagnostics for the ISC, ISL and ISX engines (with CM2250).  This Cummins fault code manual is the same information dealer technicians for ECM diagnostics.

These manuals show the fault codes and provide a step-by-step procedure to diagnose /repair ECM issues.  This is a huge set of manuals, consisting of 5 total manuals, each manual has approximately 800-900 pages.  Stacked up, these manuals are almost 12 inches high. This manual set is a real money saver because this single set provides coverage for 4 engine models, ISB, ISC, ISL and ISX.
