# Service bulletin 122\-T7Y5Q\-12 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: 10125213 - Published by NHTSA: 2017\-12\-14 - Manufacturer's number: 122\-T7Y5Q\-12 - Manufacturer's date: 2017\-11\-06 - NHTSA component: ELECTRICAL SYSTEM ## NHTSA's summary Information: This document updates information previously published in EQ 1105, EQ 1105, and EQ 1401. To provide stable voltage and sufficient current throughout certain service operations, you should connect the vehicle to a battery charger \(sometimes referred to as a power supply\). However, you may experience ECU programming and coding issues if the chosen battery charger has insufficient power. Many workshop manuals currently advise use of a battery charger with a 40 or 70 A current rating. However, with the increasing current requirements of modern Porsche vehicles, we recommend a battery charger capable of producing a minimum current of 90 A. ## The document - [NHTSA's copy of the document (PDF)](https://static.nhtsa.gov/odi/tsbs/2017/MC-10125213-9999.pdf) - [If that address does not open, try this one](https://static.nhtsa.gov/odi/tsbs/2017/MC-10125213-0001.pdf) The document is the manufacturer's.
