  • Page 7: Introduction

    CHAPTER1 PIWIS Tester III (PT3) Introduction This brochure describes the general functions of PIWIS Tester III (PT3). It does not replace the operating instructions, function descriptions and terms of use in PT3 and the PIWIS information system. The brochure is divided into a general section, the Windows 8 tester interface and the specific diagnostic applications with the respective functions.

  • Page 8: Objective

    Reasons for the introduction of PIWIS Tester III Ever increasing vehicle complexity and the number of system features. “ The revised diagnostic software is the sole property of Porsche and is protected “ by copyright law, which results in a certain level of dependence when procuring the corresponding hardware.

  • Page 9: Software

    CHAPTER1 PIWIS Tester III (PT3) Software New operating system based on Windows 8.1 and improved diagnostic software. “ This allows greater effectiveness and efficiency in the core service process. Significantly revised ‚Guided Fault Finding‛ (GFF) means that repeat repairs “...

  • Page 12: Package 3 - Starter Kit

    PIWIS Tester III (PT3) Package 3 - Starter kit With the introduction of PT3, the Porsche Centre has (for a limited time period) a unique opportunity to procure a starter kit. The starter kit contains 2 x PT3 incl. 2 x VCI in white cases and 1 x measuring equipment in a black case.

  • Page 13: Getting Started/First Steps

    In order to permit use of the PT3 with all its functions, the tester must be enabled by entering a licence key. The following steps are necessary to do this. The current address data (name and address of the Porsche Centre) must first be set using the ‚Address‛ tab.

  • Page 14: Tester Imprint

    PIWIS Tester III (PT3) This request key must then be printed on the previously configured default printer by clicking ‚Print key‛ and must be sent to the importer’s PIWIS coordinator by fax or e-mail attachment, for example. The licence key can also be requested over the phone in exceptional cases with the agreement of the importer.

  • Page 15: Certificate Handling

    CHAPTER1 PIWIS Tester III (PT3) Once the tester imprint (licence key input) has been performed, all functions are enabled and are immediately ready for use. After the tester has been successfully imprinted and enabled, the grey ‚Licence information‛ fields are displayed in the Tester imprint application.

  • Page 16: Pt3 Registration

    PIWIS Tester III (PT3) The imported certificate can also be deleted in this application. The certificate is deleted from the tester after clicking the ‚Delete certificate‛ button and confirming the security prompt. The certificate must be deleted if it has expired and has been replaced by a new certificate.

The 100-amp clamp-on ammeter with the yellow colour code is used for measuring small currents, e.g.
  • Page 29 CHAPTER1 PIWIS Tester III (PT3) If this calibration process is cancelled, measurements can be taken while bearing in mind that the clamp-on ammeters are not calibrated and the measurement result is therefore unacceptable. The clamp-on ammeters issue an acoustic signal (buzzing) while they are being calibrated.

  • Page 30: Oscilloscope

    PIWIS Tester III (PT3) If a voltage measurement was preselected, for example, the URD measuring cable must be inserted in channel 1. The LED at the test socket on the test box lights up red so that the user must insert the URD cable with the red marking rather than a clamp-on ammeter.
  • Page 31 CHAPTER1 PIWIS Tester III (PT3) Sockets for the channels The sockets can be shared among the four displayable measurement channels. There are 4 physical measurement channels available. For example: ‚Ch1#3 10 A‛ means socket 3 is switched on display channel 1, 10 A per division.
