# Service bulletin SSM 54291

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 2026 Transit vehicles built with the Delivery Assist feature \(minor feature code AAEAZ\) may exhibit diagnostic trouble code \(DTC\) U2013:04 stored in the accessory protocol interface module \(APIM\) when a diagnostic self\-test is performed. To confirm a vehicle is built with minor feature code AAEAZ, review the build information by double\-clicking the vehicle identification number \(VIN\) in the upper left corner of the Professional Technician System \(PTS\). If there are no observable symptoms with the audio controls, no further action is required. Replacement and/or programing of the APIM or audio controls will not resolve this condition. If there is an observable symptom, follow normal Workshop Manual diagnostics.
