FUNCTION

The DEF Doser Fluid Supply Module supplies diesel exhaust fluid to the dosing system as part of the vehicle’s emissions aftertreatment system. Proper DEF supply is necessary for the dosing system to operate as designed.

A worn, damaged, or failing DEF Doser Fluid Supply Module may cause symptoms such as:

• DEF supply or pressure-related faults
• DEF system warning messages
• Incorrect or insufficient DEF delivery
• Aftertreatment system fault codes
• Reduced emissions-system performance
• Engine derate or related operating restrictions

WHY REPLACE A DEF DOSER FLUID SUPPLY MODULE?

A faulty DEF Doser Fluid Supply Module can prevent the aftertreatment system from receiving the required DEF supply. Replacing a defective module with the correct Genuine OEM Cummins component can help restore proper DEF system operation and support the intended function of the emissions control system.
