# Service bulletin 122\-F3A8L\-09

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.

- Type: Service bulletin
- NHTSA id: 10127494
- Published by NHTSA: 2018\-01\-29
- Manufacturer's number: 122\-F3A8L\-09
- Manufacturer's date: 2016\-08\-08
- NHTSA component: ELECTRICAL SYSTEM

## NHTSA's summary

This campaign includes steps where control unit\(s\) in the vehicle will be programmed with the PIWIS Tester. The vehicle voltage must be maintained between 13.5 volts and 14.5 volts during this programming. Failure to maintain this voltage could result in damaged control unit\(s\). Damage caused by inadequate voltage during programming is not a warrantable defect. The technician must verify the actual vehicle voltage in the PIWIS Tester before starting the campaign and also document the actual voltage on the repair order. Please refer to Equipment Information EQ1401 for a list of suitable battery chargers/power supplies which should be used to maintain vehicle voltage. Due to a software error in the gateway control unit, the optional lightweight battery \(lithium\-ion battery\) \- if installed in the vehicle \- will not charge using the Porsche Charge\-o\-mat Pro charger when this is used via the cigarette lighter or 12\-volt plug socket in the vehicle. As a result, the lightweight battery can go flat if the vehicle is parked up for a long time. The charging function works, however, if the charger is connected directly to the vehicle battery using the optional clamp adapter.
