# Service bulletin SSM 50346

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 2018\-2021 Ford and Lincoln vehicles may exhibit inoperative remote features via the Ford Pass/Lincoln Way mobile app, incomplete user authorization, no modem electronic serial number \(ESN\) displayed or DTCs U2100 and/or B156D in the telematics control unit \(TCU\). These symptoms may persist even after performing a TCU software update and/or replacement. To correct this condition, start a new session with the latest version of the appropriate diagnostic scan tool and perform a PMI on the TCU. If issues persist, open a hotline assistance request and include the IDS version \(if applicable\) used to perform the PMI and the Authorization Status PID value in the TCU datalogger. For claiming use causal part 14G229 and applicable labor times in Section 10 of the Service Labor Time Standards \(SLTS\) Manual.

## Other bulletins for the same vehicles and component

- [SSM 52476](/bulletins/10254138.md), 2024-05-03, Service bulletin: EQUIPMENT. All accessory stick\-on keyless entry keypads come with a wallet card containing the master code. If the accessory keypad was factory installed, this card will be placed in the glove box and should be handed to the vehicles owner during initial delivery. Unlike the integrated \(wired\) factory keypad, the accessory keypad master code cannot be retrieved from the vehicle using a diagnostic scan tool. If the wallet card for an accessory keypad is lost, follow these steps to recover the code. Dealer Key Code access is granted through the Dealer Program Enrollment System \(DPES\); dealership management can authorize users. The authorized user must go to FMCDealer.com \> Parts and Service \> Parts Product Line Information \> Keys/Entry Devices \> Aftermarket Keyless Entry Keypad Code Access. Follow the instructions on the screen to obtain the master code for the accessory keypad.
