What the bulletin says
Source: NHTSA's summary of the manufacturer's communicationSome 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.

Common questions
Source: NHTSA, 49 CFR 579.5Is Ford SSM 52212 a recall?
No. A service bulletin is a manufacturer communication filed with NHTSA under 49 CFR 579.5; a safety recall carries an NHTSA campaign number (two digits, a letter, six digits) and a federal duty to repair for free. Check the vehicle’s recalls by VIN at nhtsa.gov/recalls, or on its page here.
Is the SSM 52212 repair free?
Not automatically. A service bulletin describes how to diagnose or repair a condition; who pays depends on the warranty in force, any extension, and the dealer. Quoting the number can save a diagnosis either way.
Which vehicles does SSM 52212 cover?
The manufacturer filed it against 1 model year: 2024 Ford F-150. Whether one particular vehicle is affected is a matter of its VIN and its build, not its model year alone.
