# Service bulletin SSM 50039

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.

- Type: Service bulletin
- NHTSA id: 10201013
- Published by NHTSA: 2021\-09\-04
- Manufacturer's number: SSM 50039

- NHTSA component: ELECTRICAL SYSTEM

## NHTSA's summary

Some 2016\-2021 Ford or Lincoln vehicles equipped with SYNC 3 or SYNC 4 may exhibit a blank screen or other various SYNC symptoms only when the vehicle is in transport mode. This is considered normal due to the power saving features enabled while in transport mode. It is beneficial for battery life to keep the vehicle in transport mode until the vehicle is prepped for sale. To prevent a SYNC system lockup during transport mode deactivation, follow the Workshop Manual \(WSM\) procedure exactly allowing time for the SYNC system to complete its tasks such as fully booting up or powering down and shutting off before moving to the next step of the procedure. If the vehicle exhibits a blank screen or SYNC symptoms after transport mode deactivation, refer to WSM, Section 415\-00 for normal diagnosis. The SYNC version can be confirmed via OASIS.

- [SSM 55149](/bulletins/11037295.md), 2026-09-12, Service bulletin: UNKNOWN OR OTHER; ELECTRICAL SYSTEM. Some 2021\-2024 Bronco Sport vehicles equipped with a 1.5L may exhibit a lack of air conditioning \(A/C\) cooling while at a stop and idling in ambient temperatures of 100°F \(38°C\) or higher. In addition, there are no diagnostic trouble codes \(DTC\) present related to A/C system functionality, refrigerant charge levels are to specification and system is free of refrigerant leaks and/or A/C compressor related concerns. Customers may also report that A/C system cooling will be restored once the vehicle starts moving or placed in park/neutral.\<br /\>\<br /\> This condition does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time. Inform customers that they can continue to drive the vehicle and engineering is currently working on a solution for this condition that is expected in Q4 2026. Replacement or reprogramming of any components will not resolve this condition. Monitor Professional Technician System \(PTS\) for additional information and schedule service appointments for customers once the repair becomes available.\<br /\>\<br /\> If the vehicle exhibit
