# Service bulletin SSM 53688

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\-2025 Aviator vehicles equipped with air suspension may exhibit a drive malfunction and/or suspension fault message in the instrument panel cluster \(IPC\) with diagnostic trouble codes \(DTCs\) B1041 and U2100 stored in the suspension control module A \(SUMA\). This may be due to the SUMA entering diagnostic service mode following suspension system diagnosis or repair. Clear DTCs using FDRS \> "SUMA \> Transport and Factory Mode Deactivation" function. For other DTCs refer to Workshop Manual \(WSM\) \> Section 204\-05 Vehicle Dynamic Suspension for normal diagnostics.
