  Summary

  Some 2015-2021 Ford and Lincoln vehicles may exhibit an illuminated MIL with diagnostic trouble codes (DTC) P0011, P0012, P0014, P0015, P0016, P0017, P0018, P0019, P0021, P0022, P0024 and/or P0025. This may be due to small debris causing the VCT solenoid to stick. Before attempting any component diagnosis or replacement of the VCT solenoid, refer to Powertrain Control and Emissions Diagnosis (PC/ED) pinpoint test HK12 to cycle the affected VCT solenoid 10 times to attempt to clear the debris. For claiming, use causal part 6M280 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.

  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.

In the interim, let the customer know that the radio will still function without Bluetooth and schedule a follow-up appointment with the customer for late February. Once the update becomes available, contact the customer and confirm the service appointment is going forward. Monitor OASIS for additional information and schedule service appointments for customers once the repair becomes available.

  Summary

  Some 2009-2020 Ford and Lincoln vehicles equipped with turbochargers may exhibit an oil leak from the turbocharger oil supply or return tubes, O-rings or 6.7L pedestal gasket. Although oil may collect on the turbocharger, it is very rare for a turbocharger to leak oil. To isolate the source of the leak, refer to Workshop Manual (WSM), Section 303-00 General Information > Diagnosis and Testing > Engine > Engine Oil Leaks - Fluorescent Oil Additive Method procedure. When an oil leak is present at a turbocharger oil supply or drain tube, remove the affected oil tube and inspect for damage, and replace the O-ring seals, pedestal gasket or oil tube as required. Refer to WSM, Section 303-04. For claiming, use the affected oil tube or pedestal gasket as the causal part and applicable labor operations in Sections 6 and 9 of the Service Labor Time Standards (SLTS) Manual.

  Summary

  This customer satisfaction program updates the TCM software in affected vehicles to provide improved detection and over warning of electrical circuit failures in the TCM. As communicated in a previous Customer Satisfaction Program (14M02), electrical circuit failures within the TCM may develop and result in intermittent symptoms of loss of transmission engagement while driving, no-start, or a lack of power. Updating the TCM software will help ensure the vehicle operator is alerted to potential issues with the TCM prior to failure.
