Some 2013-2015 Lincoln MKT and MKS vehicles built on or before May 5, 2015 may exhibit an adaptive drive malfunction message in the instrument cluster with possible DTCs C110D and/or C110C.
Raise the vehicle on a hoist. Remove the front right and left wheels. Disconnect connector C1668 on the left front strut assembly and C1669 on the right front strut assembly. Remove the tape and plastic convolute around the take-out to connector C1668 and C1669 and the main wire harness, approximately two inches in each direction from the take-out.
Inspect for wire damage to the main harness for any exposed/broken copper under the wire insulation. Isolate any chafed/corroded wiring and replace connector (main harness 14290 side only) C1668 and C1669 with a new pigtail connector P/N 3U2Z-14S411-GVA. Wrap the main harness wiring two inches in both directions from the take-out and wrap the entire wiring of the new pigtail connectors with Coroplast electrical wire harness tape (P/N NA1837X) or equivalent. Note that normal electrical tape does not have the anti-abrasion properties required to protect the wiring.
Replace the original convolute and cover with standard electrical tape. Reconnect connectors C1668 and C1669 (for MKT, make sure the connector take-out is routed behind the main wiring harness). Reinstall the front wheels, lower the vehicle and clear any DTCs.
