Frequently Asked Questions
Is the AWD system fully covered, including the Power Transfer Unit?
Yes. The manual dedicates a complete section to the AWD driveline, covering Active Torque Coupling diagnostics, PTU fluid service and removal, rear driveshaft, rear differential, rear halfshafts, and the 4X4 control module with full DTC and symptom charts. PTU fluid degradation is a well-documented weak point on AWD Flex models, and the correct service intervals and fluid specifications are detailed inside.
Does this cover both the standard V6 and the EcoBoost version?
Both engines are fully covered. The naturally aspirated 3.5L Ti-VCT V6 (10.8:1 compression, paired with the 6F50 transmission) and the twin-turbocharged 3.5L GTDI EcoBoost V6 (10.0:1 compression, paired with the 6F55 transmission) each have dedicated engine management, fuel system, turbocharger, and mechanical sections with complete torque specs and VCT procedures.
Are wiring diagrams included for the electrical and safety systems?
A full HTML wiring diagrams file is bundled in the same download. Coverage includes electronic engine controls for both V6 engines, 6F50/6F55 transmission controls, AWD system wiring, PATS anti-theft, TPMS, supplemental restraint system, instrument cluster, power liftgate, power seats, lighting, charging system, and module communications network — with connector repair procedures and component location views.
