Introduction

GENERAL

The Tech 2 is a portable instrument designed to assist fault diagnosis and the repair of electronic systems with self-diagnosis. The Tech 2 is the ISAT scan tool's successor and will eventually replace the ISAT entirely.

Faults arising in systems with self-diagnosis are detected and saved in the system's control modules. The Tech 2 reads the system's saved fault information and the fault is presented in the form of a diagnostic trouble code as well as the source of the fault and its cause in plain text. The Tech 2 can check the selected system via read and activation commands. By means of the Tech 2 it is also possible to:

^ program and adjust control modules
^ obtain readings of measured values
^ record sequences of measured values
^ activate certain functions
^ obtain readings of system information

A fault diagnosis procedure for the selected system will be found in the relevant location.

How To Use The Manual
In order to make full use of the equipment, the person who is going to use it should first carefully read through this information.

Knowledge Of The Car's Systems
Although the Tech 2 is a powerful instrument, it cannot replace the knowledge and experience of workshop personnel.

To make the best use of the equipment it is necessary to have acquired thorough knowledge of Saab cars. We recommend using the Tech 2 in conjunction with the relevant service information.

Before using the Tech 2 you should also study the latest service information bulletins.
