Dongfeng 3615010-K57J0 Aftertreatment Control Module Assembly

The 3615010-K57J0 is an electronic control unit (DCU/ACM) designed for the selective catalytic reduction (SCR) aftertreatment system on Dongfeng heavy-duty trucks compliant with China IV emission standards. It controls urea injection dosing, monitors nitrogen oxide (NOx) sensor signals, and communicates via J1939 CAN bus with the engine ECU. The unit integrates the CM1880 architecture platform commonly supplied by Bosch for Cummins ISLe and ISL8.9L engine applications. This assembly serves as a direct replacement for multiple Dongfeng OE part number variants including 3615010-T68M4, 3615010-TL381, 3615010-T25FD, and 3615010-TF980. It is engineered for 24V vehicle electrical systems and rated for extended operating temperature ranges typical of commercial vehicle under-hood or frame-rail mounting locations. The housing provides IP67 ingress protection against dust and water jets.
