Hi there my name is ***** ***** I'd like to try and help. Those are derate faults and are informational only. We do not troubleshoot those faults. However they usually come up with another fault that needs to be diagnosed. Do you have any other active faults currently

Hi Andy I do not have any other code but this code. 1FVACWDT2GHGZ4373
Phone call session started
Customer reply replied 3 months ago
ECM code -DT90122.12

The newest version is DT90122.14 and if you calibrate the ecm to the newest version, it should take care of the issue.
