Introduction

Introduction

This guide contains instructions for the installation of the Portable Diagnostic Unit hardware in Aston Martin Dealer workshops. To achieve maximum benefit from the system, please follow the instructions carefully. The following System Diagram shows the principal system components and panel details.

This introduction briefly describes the system and its capabilities. This is followed by the installation and Power-Up procedures which give detailed instructions on how to start the system and access the self-contained Interactive Training Programme.

The subsequent sections detail the fault diagnosis and maintenance procedures.

WARNING: The equipment must only be used by trained personnel. Care should be taken to use the equipment in accordance with the operating procedures. Observe all safety warnings in this guide. If any part of the system is damaged do not use it. Call your local GenRad Service Centre immediately for a substitute part. Refer to 'Parts Ordering'.

WARNING: If the system is used to measure high voltages, these voltages can appear on the pins of other connectors in the system. Ensure that socket covers are fitted on unused sockets. Ensure that all connections are made prior to applying the high voltage to the probes. Do not leave the equipment unattended in this state. The maximum voltage that may be applied between the test probes is 150 volts AC or DC.

The Aston Martin Diagnostic System

The Aston Martin Diagnostic System is a new generation diagnostic tool which fulfils a number of functions in aiding the technician to quickly and accurately locate faults. The heart of the system is the Portable Diagnostic Unit, a lightweight powerful computer/measurement system providing a step-by-step user friendly interface for the technician.

PDU functions include:

• Data Logger - The ability to monitor and record control module signals even whilst the vehicle is being driven.
• On-line Help - Containing detailed descriptions in the operation of the vehicles electronic components.
• Vehicle Setup - The ability to setup various adjustable parameters to their optimum settings.
• Diagnostics Trouble Codes - The ability to extract recorded fault information from the DB7's control modules.

Each of these functions is described in detail in the PDU Users Guide.
