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.
