Technical Service Bulletin SSM 54173 — 2023 FORD F-550 SD

Some 2023-2025 F-Super Duty vehicles may exhibit a no crank/no start or intermittent no crank/no start with multiple warning indicators and DTC U0100 stored in the anti-lock brake system (ABS), audio front control module (ACM) and power steering control module (PSCM). This may be due to an incorrectly tightened ground 113 (G113). Inspect G113 for proper connection and tighten to 12 Nm (8.9 ft-lb). If the condition remains after tightening G113, continue with normal diagnostics. Refer to Workshop Manual, Section 303-06 Starting System outside of this article. For claiming, use causal part 12A581 and labor operations 12650D and 12650D45WD.
