APPLICATIONS

Designed for compatible Cummins diesel engine and Selective Catalytic Reduction (SCR) emissions systems. Exact fitment should be confirmed using the Part Number, VIN, vehicle model, engine, and configuration.

FUNCTION

The DEF Doser Fluid Supply Module helps deliver diesel exhaust fluid within the emissions aftertreatment system. Proper DEF supply is necessary for the SCR system to operate as designed and support the reduction of nitrogen oxide (NOx) emissions.

A worn, damaged, or failing DEF Doser Fluid Supply Module may cause symptoms such as:
• DEF supply or delivery problems
• SCR system performance issues
• DEF system warning messages
• Check engine or emissions system warnings
• Reduced engine performance or derate conditions
• Improper or interrupted DEF dosing

WHY REPLACE A DEF DOSER FLUID SUPPLY MODULE?

A faulty DEF Doser Fluid Supply Module can prevent the aftertreatment system from receiving DEF correctly. Replacing a damaged or malfunctioning module with a Genuine Cummins part can help restore proper DEF delivery and support normal operation of the SCR emissions system.
