The Environmental Protection Agency (EPA) has mandated that a DEF quality sensor must be installed on certain engines built after 2016. This new DEF quality sensor is integrated into the DEF header inside the DEF tank. The new style DEF header utilizes CAN C communication, so the wiring to the DEF header has been slightly modified on product going forward. However, the Dosing Control Unit (DCU) remains compatible to both setups with the latest engine software. ( 507-7605 Engine Software (24V DCU) or 507-7546 Engine Software (12V DCU)). As part of the DEF quality sensor implementation, a new configuration parameter setting is used on the engine Electronic Control Module (ECM) in Cat ET to identify whether a DEF quality sensor is"installed" or "not installed". Below are some different diagnostic codes for incompatible hardware and configuration setting as well as different service scenarios that may be encountered with this change and how to resolve any issues in these particular service scenarios. In addition to this Special Instruction, there is a video detailing these changes posted on Cat Channel 1.Diagnostic Codes When Parts/Settings Are Not Compatible

Replacement Industrial Engine (2016 and earlier builds)
Replace with new engine (old engine no longer serviceable). Update to DEF quality sensor by installing a new DEF header, wiring harness, and DCU software and changing DEF quality sensor configuration status to "installed" in Cat ET.Replacement Machine Engine (2016 and Earlier Builds)
Replace with older service replacement Engine Arrangement Complete (EAC) engine (no other changes needed, confirm that DEF quality sensor configuration is set to
