- Summary
- Some 2023 Expedition/Navigator vehicles may experience a heated seat indicator center display screen/switch mismatch (Navigator only) or speed assist off switch greyed out (Expedition only). This may be due to the software in the accessory protocol interface module (APIM). To correct the condition, follow the Service Procedure to reprogram the APIM using the latest level of the Ford Diagnosis and Repair System (FDRS) scan tool. The APIM software update that addresses the symptom listed in this article may have been delivered over-the-air (OTA) via Ford Power-Up software updates to connected vehicles that have automatic updates enabled through the center display screen. Enter the vehicle identification number (VIN) in Professional Technician System (PTS) and check the OTA Dashboard under the Connected Vehicle tab for OTA update history. If an update to the APIM has been successfully completed recently and the customer is reporting the symptoms are no longer present, this article may not apply.
