# Service bulletin SSM 51748

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 2023 F\-Super Duty vehicles equipped with a wireless charging pad may exhibit an excessive buzzing noise from the WACM cooling fan. This may be due to the wiring harness or electrical tape contacting the cooling fan. Remove the WACM and inspect for contact between the wiring harness and the WACM cooling fan. Refer to Workshop Manual, Section 414\-06. If contact is found, reroute the wiring harness away from the WACM cooling fan to eliminate the noise. Use the Report a Vehicle Concern link at the bottom of OASIS to submit a report with photos attached \(if possible\) if contact is found between the wiring harness and the fan.
