# Service bulletin 122\-Y2D8V\-11

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.

- Published by NHTSA: 2017\-10\-15

- NHTSA component: ELECTRICAL SYSTEM:SOFTWARE

## NHTSA's summary

In the course of annual model improvements, various functionalities of the Porsche Communication Management \(PCM\) system have been enhanced, optimisations have been implemented and the general performance of the system has been further improved at the same time. These function enhancements and optimisations must be implemented retrospectively even for vehicles manufactured before the model improvement measures were introduced. To this end, the PCM software will be updated on the affected vehicles using an SD card. Due to the changes to the PCM, the instrument cluster must also be re\-programmed using the PIWIS Tester in order to ensure consistency between the displays in PCM and the instrument cluster.
