# Service bulletin SSM 52116

A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

## NHTSA's summary

Some 2024 Nautilus vehicles may set diagnostic trouble code \(DTC\) B146F:00 in the drivers multi\-contour seat module \(SCMG\) and/or passenger multi\-contour seat module \(SCMH\) when a diagnostic self\-test is performed. This may be due to a communication error to the SCMG/SCMH within a specified timeframe. Replacement or reprogramming of the SCMG/SCMH will not resolve this condition. B146F:00 should be ignored and no further service action is required if no other DTCs are present in the SCMG/SCMH, no warning indicators are illuminated while the engine is running, and no symptoms present.

- [SSM 52393](/bulletins/10252649.md), 2024-04-04, Service bulletin: EQUIPMENT. Some 2024 Nautilus vehicles may exhibit difficulty removing shipping door protectors or white RapGard during predelivery. This may be attributed to varied environmental conditions during transit from the assembly plant to the dealerships. If possible, bring the vehicle into the shop to warm up and stabilize to a room temperature closer to 20°C \(68°F\) or higher prior to removing the plastic coverings. Running the engine may help in warming the hood wrapping adhesive for easier removal. Also, reuse the white RapGard that was removed from the car to dab/remove any adhesive residue left behind. For general guidelines, refer to the Warranty and Policy Manual, Section 2.9.00 Storage of New Vehicles.
- [SSM 52381](/bulletins/10252642.md), 2024-04-04, Service bulletin: EQUIPMENT:ELECTRICAL:INFOTAINMENT; EQUIPMENT:ELECTRICAL:INFOTAINMENT:SOFTWARE. Some 2024 Nautilus vehicles may have a clock that is inaccurate and/or weather information may not be able to update along with the inability to sign\-in to Google Automotive Services to update or edit a profile. During this time the Google Map may also not display in the panoramic display screen next to the speedometer. This may be due to a concern with the telematics control unit \(TCU\) module software. Inform customers that they can continue to drive the vehicle and that engineering is currently working on revised TCU module software for this concern. Monitor OASIS for additional information and schedule service appointments for customers once the repair becomes available. Note that it is normal for the Google Map to not appear in the panoramic display when in calm mode or when using the Waze app.
