Service bulletin SSM 50514

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary

Some 2020-2022 F-53 Motorhome Chassis/F-59 Commercial Stripped Chassis vehicles may exhibit an illuminated anti-lock brake system (ABS) warning with diagnostic trouble code (DTC) C0037 and/or C0038. This may be due to a damaged rear wheel speed sensor (WSS) ring. Minimal damage may cause DTCs and can be difficult to detect during visual inspection. If replacement is required, closely inspect the service part to ensure no damage is present and follow Workshop Manual, Section 206-09 to replace. Removal of the ABS sensor is required to avoid damage to a new ring when servicing. Use a suitable jack to aid with hub/rotor install on the axle to prevent ring damage during assembly. Some backorders may be experienced when ordering the ring. Submit a customer online parts inquiry system (COPIS) vehicle off road (VOR) ticket is recommended to prioritize orders.
