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\-2023 Mustang \(non\-GT500/GT350\) vehicles equipped with vehicle dynamic suspension may exhibit a Dynamic Suspension Fault message displayed in the IPC with diagnostic trouble code \(DTC\) B14C1:64 with no vehicle symptoms. This may be due to software within the vehicle dynamics module \(VDM\). To correct the condition, reprogram the VDM using the latest software level of the appropriate Ford diagnostic scan tool.
