Official summary
Some 2024 Nautilus vehicles may set diagnostic trouble code (DTC) U0422:00 in the all-wheel drive (AWD) module when a diagnostic self-test is performed. This may be due to a communication error between the body control module (BCM) and AWD module. Replacement or reprogramming of the BCM and/or AWD module will not resolve this condition. U0422:00 should be ignored and no further service action is required if no other DTCs are present in the BCM and/or AWD module, the BCM is configured correctly, no warning indicators are illuminated while the engine is running, and no symptoms present.
Vehicles covered
What a TSB means. Technical service bulletins are repair guidance manufacturers send to dealers — they are not recalls, and repairs are not automatically free (warranty extensions are an exception worth checking). The full document is available via NHTSA’s vehicle lookup.
