Technical Service Bulletin SSM 49349 — 2021 FORD E-450

Some 2021 E-Series chassis vehicles may exhibit a Service Advance Trac and Pre-Collision Assist Not Available message in the cluster with diagnostic trouble code (DTC) C0051 stored in the anti-lock brake system (ABS) module. Cruise control may also be inoperable. If this concern is still present after normal diagnosis, clear the DTC with the appropriate Ford diagnostic scan tool and schedule a follow-up appointment for service in March 2021. Inform the customer that engineering is working to implement a solution for this condition and advise the customer that they can continue to drive the vehicle. This condition does not create drivability concerns and has no effect on long-term durability. Once the solution becomes available, contact the customer and confirm a service appointment. Monitor OASIS for updates.
