Cummins ISX15 3582: SCR-efficiency context and applicability
Cummins’ historical ISX15 CM2250 field action identifies 3582 as an SCR conversion-efficiency fault. It does not establish that a catalyst replacement is the right repair for your truck today. Arrange an engine-specific assessment with the complete code history.
Application & limits
Cummins TRP t2035 revision D, released 10 December 2019, concerned certain ISX15 CM2250 engines and printed an expiry of 1 August 2023 for the U.S. and Canada. It is historical evidence of terminology, not current coverage or an X15/CM2350 diagnostic procedure.
What the symptom or code tells you
The old field action had engine, fault-history and other eligibility limits. Its existence cannot establish present warranty coverage, participation or a replacement entitlement.
For a current service request, the ESN, installed emissions system, software and related faults must be checked first. We do not turn an expired field action into a current diagnosis table.
Information to send
Use details already available from the normal operator position or your records. Do not run a test or approach a hazard to collect them.
- Engine serial, ISX15 service model and truck year/VIN.
- Exact 3582 message and every associated active/inactive fault.
- Previous aftertreatment repair records and campaign paperwork, if any.
- Current symptoms, stop warnings and truck location.
What the mechanic assesses
The mechanic uses current ESN-matched diagnostic information to establish the monitored condition and suitable next tests. Ask an authorized OEM service provider about any present campaign or warranty eligibility. This guide does not quote a repair price, promise coverage or authorize catalyst replacement from the code alone.
Prepare a repair request
Text the machine or vehicle, exact symptom and location. We confirm scope, safe access, parts needs, pricing and availability before a visit.
