SSM 548002026-05-14. Service bulletin. ELECTRICAL SYSTEM; STRUCTURE:BODY. Some 2025-2026 Explorer/Aviator and 2026 Expedition/Navigator vehicles may exhibit an intermittent inoperative remote start feature using either the key fobs or the Ford/Lincoln App. This may be due to the software in the body control module (BCM). After replicating the concern, use the Ford Diagnosis and Repair System (FDRS) to monitor the RMTSTRT_F_ARB_LST and RMTSTRT_F_TRGT_NM parameter identification (PIDS) in the BCM. If both PID values show "true" in any of the last 5 saved values, engineering is currently working on a solution for this condition that is expected in Q4 2026. Schedule service appointments for customers once the repair becomes available. If either of the BCM PID values do not show "true" in any of the saved values, refer to Workshop Manual (WSM), Section 501-14 Handles, Locks, Latches, Entry Systems > Diagnosis and Testing > Locks, Latches and Entry Systems > Pinpoint Test R (Explorer/Aviator)/Pinpoint Test V (Expedition/Navigator) for normal diagnostics and repair as necessary outside of this article.
