Service bulletin 18-042-20
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Flash: Powertrain Control Module (PCM) Updates This bulletin involves reprogramming the Engine Control Module/Powertrain Control Module (ECM/PCM) with the latest available software. Customers may experience a Malfunction Indicator Lamp (MIL) illumination. Upon further investigation the technician may find that one or more of the following DTCs have been set:There will be a choice between two calibrations. One for vehicles that utilize an ammonia sensor and one for vehicles that have had the ammonia sensor removed. Be sure to select the correct software based on vehicle configuration.Improvements to prevent or reduce MIL illumination when no defect is present for:P2201 - Aftertreatment Nox Sensor Circuit Performance - Bank 1 Sensor 1(Ammonia delete systems only). P229F - Aftertreatment NOx Sensor Circuit Performance - Bank 1 Sensor 2. P20EE - SCR NOx Catalyst Efficiency Below Threshold - Bank 1(New Improvements for ammonia delete systems only). P202E - Diesel Exhaust Fluid (DEF) Reductant Injector Performance(New Improvements for ammonia delete systems only). P218F - Reductant No Flow Detected. P1C55 - NOx Sensor Intermittent - Bank 1 Sensor 1. U0001 - CAN C Bus. P229E - NOx Sensor Circuit - Bank 1 Sensor 2(Non-ammonia delete systems only).
