1.0 DIAGNOSTIC CAPABILITIES
DIAGNOSTIC TOOLSET OVERVIEW
The Diagnostic Toolset consists of a hand-held Tester and attachments, which allows the
use of one tool for many diagnostic applications. The Toolset is designed so that future
diagnostic applications can easily be incorporated into the existing Toolset.
The diagnostic capabilities of the Toolset components are described in this section. A
description of the hardware related to each component is included in the following
sections.
THE TESTER
The Tester is used by professional technicians as an aid in diagnosing and repairing
automotive electrical and electronic systems. It is designed to test Electronic 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 Diagnostic
Toolset, the Tester employs plug-in program cards or cartridges, and can be adapted to
operate with virtually all electronic systems—from the simplest to the most complex.
The Tester supports diagnosis of electronic systems on many makes of vehicles in addition
to Toyota and Lexus.
The Autoprobe supplied with the Tester Kit provides additional troubleshooting
capabilities. The Autoprobe is used as a smart digital voltmeter (DVM) to monitor input/
output signals between the ECM/ECU and sensors and actuators, in addition to use as a
probe for the oscilloscope function.
When the program card 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.
Display sensor operation data.
Display actuator control data.
Display ON/OFF status of switch signals.
Test feed-back systems such as the O2 sensor.
Command clearing of some ECM/ECU trouble codes.
Troubleshoot using the Autoprobe.
Troubleshoot intermittent problems with Snapshot mode.
Print test results to provide a permanent record.
The Tester hardware components are described in Section 2.0 Tester Kit Components on
page 13.
