2021-2022 F-150 - May Not Communicate With Emissions Testing
Equipment
Some 2021-2022 F-150 vehicles may not be able to communicate with some emissions testing
equipment. Engineering is aware of the concern and is currently working on a solution expected in 2nd
Quarter 2023. Monitor OASIS for updates. As a temporary corrective action, technicians may attempt one
of the following: (a) Leave the engine running when performing the emissions test, even when the
machine prompts to shut the engine off. (b) If a Ford Diagnosis and Repair System (FDRS) tool is
available at the same location as the emissions testing equipment, use the FDRS tool to download and
run the On-Demand DTC self-test on the audio front control module (ACM) and clear diagnostic trouble
codes (DTCs) in the ACM, even if none are present. Then within the same key cycle, connect to the
emissions test machine and perform the emissions test immediately.
