1. INTRODUCTION
USING THIS MANUAL
To increase their effectiveness with the Tech 2, familiarize yourself with the format and information
contained in this guide.
VEHICLE SYSTEM FAMILIARITY
While the Tech 2 is a powerful tool, it cannot replace knowledge and skill. To get the most out of the Tech 2,
you must have a complete understanding of vehicle systems.
When using the Tech 2 to diagnose a vehicle, we recommend that you also refer to the service manual and
the latest service bulletins.

Introduction
Page 1-2 Tec h 2
THINGS YOU SHOULD KNOW
TECH 2 DISCLAIMER
The Tech 2 is designed for use by trained service personnel only. It has been developed for the sole purpose
of diagnosing and repairing automotive systems with electronic controls and interfaces. Every attempt has
been made to provide complete and accurate technical information based on factory service information
available at the time of publication. However, the right is reserved to make changes at any time without
notice.
FCC COMPLIANCE
This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to
Part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial environment. This equipment generates, uses,
and can radiate radio frequency energy. If not installed and used in accordance with the instruction manual,
it may cause harmful interference to radio communications. Operation of this equipment in a residential area
is likely to cause harmful interference, in which case the user will be required to correct the interference at
his or her own expense.
CAUTION
CAUTION! When performing any checks with the engine running in an enclosed space
such as a garage, make sure there is proper ventilation. Never inhale
exhaust gases; they contain carbon monoxide, a colorless, odorless,
extremely dangerous gas that can cause unconsciousness or death.
CAUTION
CAUTION! To help avoid personal injury, always set the parking brake securely and
block the drive wheels before performing any checks or repairs on the
vehicle.

Introduction
Te c h 2 Page 1-3
VDE CERTIFICATION (FOR EUROPEAN
USE)
This equipment complies with the requirements of VDE 0871/6.78. Improper use or maintenance neglect
may cause unacceptable radio or TV interference.
TAKING THE PRODUCT BACK AND
RECYCLING
Applicable to product that is sold into the European Union, the European Union has passed a directive
called Waste Electrical and Electronic Equipment, or WEEE for short, to ensure that systems are setup
throughout the EU for the collection, treating and recycling of electronic waste.
CAUTION
CAUTION! The Tech 2 uses parts that can produce arcs or sparks. When used in a
garage environment, the Tech 2 must be located not less than 18 inches
(460 mm) above the floor.
NOTE
• Do NOT clasp battery clips together when connected simultaneously
to the vehicle's 12-volt cigarette lighter or power supply. Reverse
polarity in the vehicle's cigarette lighter may be present. Damage may
occur to the Tech 2 or to the vehicle.
• If power is applied to the Tech 2 and the display remains blank,
reverse polarity in the cigarette lighter may be present. Damage to the
Tech 2 could occur. Do NOT connect the DLC cable to the vehicle.
Verify that the center contact of the vehicle's cigarette lighter has +12
volts and that the outer contact is grounded.
• Turn off the power before inserting or removing the PCMCIA card.
Continual removal and reinsertion of this card is not recommended.
• Align all cards and components carefully before inserting them into
the Tech 2.
• Make sure all cables and adapters are firmly connected before starting
to use the Tech 2.
• Always read the instructions completely before attempting a new
procedure.
• Do not connect the RS-232 and RS-485 ports to a direct phone line.
The Tech 2 was not designed for this method of communication.
• Do not place the Tech 2 so that the tilt stand can make contact with the
vehicle battery terminal as this could short out the battery.

Introduction

This ensures that the devices are recycled in a resource-saving way representing no danger to health or the
environment.
The WEEE symbol (see Figure 1-1) on the product or its packaging shows that the product must not be
disposed of as residual garbage. The user is obliged to collect the old devices separately and return them to
the WEEE take-back system for recycling.
The WEEE directive concerns all Bosch devices but not external cables or batteries. For more information
on the Bosch GmbH Recycling Program, contact one of the Vetronix/Bosch Group sales and service
