SSM 515362023-05-04. Service bulletin. For 2000-2024 Ford and Lincoln vehicles, swapping a module from a vehicle for diagnosis purposes is likely to cause errors and is not recommended. It is also not recommended to order a replacement module using a vehicle identification number (VIN) from a different vehicle. Most modules on these affected vehicles are VIN/vehicle specific and hardware variations between modules do exist. Swapping a module from a vehicle or ordering a module using a different vehicle/VIN can cause ineffective repairs and additional vehicle down time. Make sure all appropriate Workshop Manual (WSM) procedures are followed when diagnosing the condition prior to all module replacements and only order modules using the correct VIN.

The Driver ID message may also be accompanied by a connectivity loss including FordPass app displaying stale data or dates, unable to send cellular based remote commands through FordPass, and/or connectivity menu on SYNC not accessible. This may be due to the software in the gateway module (GWM). To correct the condition, follow the Service Procedure to reprogram the GWM.
