# Service bulletin CSR 513

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

Engine Power Source \(EPS\) has launched a technical bulletin for MVP controllers with potential memory loss. These controllers have a display on Altec DC1317 and DRM12 chippers. Affected units have the potential for the display to go blank due to a voltage drop during the boot\-up cycle. This can be fixed by reloading the firmware and configuration files. Please refer to the communication from EPS. No action is required unless you are experiencing issues.
