For MKT vehicles, be sure to route the connector take-out behind the main harness.

Some 2013-2015 Lincoln MKT and MKS vehicles built on or before May 4, 2015, may exhibit an Adaptive Drive Malfunction message in the instrument cluster with possible diagnostic trouble codes (DTCs) C110D and/or C110C.

Raise the vehicle on a hoist. Remove the right front and left front wheels. Disconnect connector C1668 on the left front strut assembly and C1669 on the right front strut. Remove the tape and plastic convolute around the take-out to connector and the main wire harness, about 2 inches in each direction from the take-out.

Inspect the wires for damage (broken or exposed copper wire). Isolate any chafed/corroded wiring and replace the connector (main harness 14290 side only) C1668 and C1669 with a new pigtail connector. Wrap the main harness 2 inches in both directions from the take-out and wrap the entire wiring of the new pigtail connectors with Coroplast electrical wiring tape or equivalent (normal electrical tape does not have the anti-abrasion properties required).

Replace the original convolute and cover with standard electrical tape. Reconnect the connectors. For MKT, make sure that the connector take-out is routed behind the main wiring harness. Reinstall the wheels, lower the vehicle and clear any DTCs.
