Abstract
According to one embodiment, described herein is an apparatus for mitigating on-board diagnostic (OBD) faults generated by an OBD system of an internal combustion engine (ICE) system having a selective catalytic reduction system with a diesel exhaust fluid (DEF) decomposition tube. The apparatus includes a fault mitigation module that is configured to monitor at least one OBD signal of the OBD system and issue a request for regenerating the DEF decomposition tube when a value of the at least one OBD signal reaches a predetermined regeneration threshold corresponding with the at least one OBD signal. The regeneration threshold is reachable prior to an OBD fault threshold corresponding with the at least one OBD signal. The apparatus also includes a regeneration module that is configured to regenerate the DEF decomposition tube according to the issued request.
