# Service bulletin C2504 A

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

This Campaign is being issued to address a small population of BES CM0904 EV104B units that were built with INVT HV DC/AC Inverters. This Campaign authorizes certified service locations to proactively replace the Power Steering and/or the Air Compressor Inverters if determined to be the INVT version. If an upfit is appropriate, the SCM Trim Parameters will require a change for each component option as needed. This is an update to the previously submitted communication.
