Some 2024 F-150 Lightning vehicles may set diagnostic trouble code (DTC) U0594:68 in the heat pump valve control module (HPVCM) when a diagnostic self-test is performed. This may be due to HPVCM sensitivity while in accessory mode. DTC U0594:68 has no effect on functionality and will automatically become a historical DTC which can be cleared. Replacement or reprogramming of the HPVCM will not resolve this condition. DTC U0594:68 should be ignored if no other DTCs are present in the HPVCM, no warning indicators are illuminated while the vehicle is on, and no symptoms present. No further service action is required.

Some 2020-2021 Escape vehicles may encounter the instrument panel cluster (IPC) odometer/trip computer changing from metric to imperial and/or the power liftgate enable/disable menu in the center stack display greyed out and/or FordPass Electrical System Fault message with DTC U0594 stored in the IPC. This may be due to the software in the IPC. To correct the condition, reprogram the IPC to the latest software level using Ford Diagnosis and Repair System (FDRS). For claiming, use causal part 10849 and applicable labor operations in Section 10 of the Service Labor Time Standards (SLTS) Manual.

Some 2021 Escape Hybrid (FHEV) customers may have received a FordPass message indicating an Electrical System Fault was detected. No warning messages in-vehicle should have occurred, but diagnostic trouble code (DTC) U0594 may be present in the instrument panel cluster (IPC). This DTC does not affect vehicle durability and no additional diagnosis or service is required for this condition at this time. FordPass message targeting has been suppressed and engineering is working to implement a solution for the DTC. Let the customer know they can continue to drive the vehicle and schedule a follow-up appointment for repair in June. Once the update becomes available, contact the customer and confirm the service appointment is going forward. Monitor OASIS for updates.
