The Multiquip 8983083800 DEF-DCM Control Unit is a genuine OEM component designed for the DCA70SSIU4F ultra-silent generator. Sourced directly from Multiquip, this control unit delivers the exact fit and electrical specification required for proper DEF system operation on the DCA70SSIU4F. As an OEM part, it meets the same standards as the original unit installed at the factory, ensuring seamless integration with the generator's diesel exhaust fluid management system.

Key Features

  • OEM-Matched Electrical Specification — Engineered to the precise control logic and output parameters required for correct DEF-DCM system function on the DCA70SSIU4F.
  • Direct-Fit Replacement — Mounts and connects exactly as the original unit, with matching connectors and mounting points for a straightforward swap.
  • Confirmed DCA70SSIU4F Fitment — Verified for the DCA70SSIU4F ultra-silent Isuzu-powered generator; use part number 8983083800 to confirm compatibility before ordering.
  • Emissions System Integrity — A functioning DEF control module is critical to keeping the generator's Tier 4 emissions system operating within regulatory compliance; a failed unit can trigger fault codes and force shutdown.
  • Genuine Multiquip OEM Quality — Backed by Multiquip's OEM supply chain, this part carries the same component-level integrity as the unit it replaces, protecting the broader DEF and aftertreatment system.

The DEF-DCM (Diesel Exhaust Fluid Dosing Control Module) manages the injection of diesel exhaust fluid into the exhaust stream as part of the generator's Selective Catalytic Reduction (SCR) aftertreatment system. It monitors system sensors and precisely controls DEF dosing to reduce nitrogen oxide emissions in compliance with Tier 4 Final standards. When this control unit fails or malfunctions, the generator may log fault codes, enter a derate condition, or shut down entirely — making prompt replacement essential to restoring full operation.
