Just noticed this on my Monthly Snapshot Report email from Ford. States from 3/23 for 23 lightning 🀷

Ford F-150 TSB 23B21 Gateway Module Programing 1000002767



Ford TSB 23B21
Make:
Ford
Number:
23B21
Title:
Gateway Module Programing
Date:
3/29/2023
Models:
2023 F-150 Lightning
Summary:
In all of the affected vehicles, the Gateway Module (GWM) may lose internet connection. This may cause the vehicle to experience an inoperative FordPass application (inability to review the vehicle's state of charge, inoperative remote start and/or inoperative remote lock and unlock). This may be combined with diagnostic trouble codes (DTC) U0146:09 stored in the telematics control unit (TCU) and U2402:00 and/or U2402:92 stored in the gateway module (GWM). Dealers are to correct the condition by updating the GWM to the latest software level via a coordinated module reprogramming. This service must be performed on all affected vehicles at no charge to the vehicle owner.

Yes I noticed it a couple days ago on the Ford site, not on Ford Pass.

Thanks for not giving me to hard of a time and sending the link to look this up. I wasn't aware of it. No eligibility for my 2021...

@KTM753, Never would my friend; I never know when I'll need help and paying it forward is what these forums have that other online places often lack πŸ‘

interestingly I will never get OTAs (long story) so I rely on FDRS for updates... this CSP has disappeared from my list so one of two things happened; either the dealer did the GWM update during recent service or ford mistakenly had it on my VIN 🀣
