2. DIAGNOSTIC CAPABILITIES

MASTERTECH KIT OVERVIEW

The Mastertech kit consists of a hand-held tester and attachments, which allows the use of one tool for many
automotive diagnostic applications. The Mastertech kit is designed so that future automotive diagnostic
applications can easily be incorporated into the existing tester.
The diagnostic capabilities of the tester components are described in this chapter. A description of the
hardware related to each component is included in the following sections.

THE MASTERTECH

The Mastertech is used by professional technicians as an aid in diagnosing and repairing automotive
electrical and electronic systems. It is designed to test Engine Control Modules (ECMs) and Electronic
Control Units (ECUs) for brake, body, and chassis systems, and their associated sensors, actuators, and cable
harnesses.
Capable of operating either as a stand-alone tool or as the control unit for the toolset, the Mastertech employs
plug-in program cards and cartridges, and can be adapted to operate with virtually all automotive electronic
systems from the simplest to the most complex.
The tester supports diagnosis of electronic systems on most US vehicles, as well as many European and
Asian manufactured vehicles.
The Diagnostic Test Leads supplied with the Mastertech kit provides additional troubleshooting capabilities.
The Diagnostic Test Leads are used as inputs to a smart digital volt meter (DVM) function to monitor input/
output signals between the ECM/ECU and sensors and actuators, and for inputs to the oscilloscope function.
When the appropriate program card and/or cartridge is installed and the tester is connected to a vehicle's
Data Link Connector (DLC), the following diagnostic functions are available:
• Display ECM/ECU Data List parameters
• Display stored trouble codes and descriptions
