From OASIS, Feb. 16: SSM 44931 - Vehicle Health Report Inoperative with Aftermarket Device Plugged Into Data Link ConnectorSome 2008-2015 Ford/Mercury/Lincoln vehicles equipped with SYNC may exhibit a message indicating Vehicle Needs 200 Miles on it to perform a Vehicle Health Report (VHR). If this message is displayed, inspect for an aftermarket device that is plugged into the Data Link Connector (DLC). Refer to Workshop Manual (WSM), Section 418-00 Module Communications Network, Description and Operation. If an aftermarket device is found, do not perform a repair or attempt a module update as the device must be removed from the DLC for SYNC VHR to operate properly. After removing an aftermarket device, cycle the ignition key once and perform a short drive to update the odometer reading. If the SYNC VHR is still not operating properly, refer to the WSM, Section 415-00 Information and Entertainment System for diagnosis by DTC or symptom.
