Technical Service Bulletin SSM 54517 — 2022 FORD EXPEDITION

Some 2022-2024 Expedition Timberline vehicles may exhibit a condition where the trail turn assist feature is disabled after a few seconds of activation. This may be due to the accessory protocol interface module (APIM) software. Replacement or reprogramming of the APIM will not resolve this condition. Inform customers that engineering is currently working on a solution for this condition and will be released via software updates delivered over-the-air (OTA) expected Q3 2026. Software will update automatically if vehicle connectivity is enabled in the vehicles settings. Schedule a service visit for customers who have disabled vehicle connectivity or who report that they did not receive the update by September 2026. Monitor Professional Technician System (PTS) for additional information.
