OVERVIEW
This training presentation will cover the use of the BOSCH Tech 2 diagnostic scan tool and the
GM Multiple Diagnostic Interface. Specifically, we will be focusing on diagnosing all GM
manufactured vehicles.
General Motors has a rich history in the diagnostic world. In fact, GM was the first automotive
manufacturer to create a diagnostic scan tool called the Tech 1. The Tech 1 began in 1994 and
was in use until late 1995. In 1996 GM moved to the Tech 2. The Tech 2 began in 1992 and
continues to service the current vehicles of today.
GM is now transitioning to a new tool called the Multiple Diagnostic Interface (MDI). Many have
assumed that the MDI will immediately replace the Tech 2, but that is not the case. The Tech 2
remains an essential tool for many vehicles through at least the 2012 model year. It will also
continue to be needed to diagnose all vehicles from previous model years. As such, it remains a
very valuable diagnostic tool and, with the launch of the MDI as a faster reprogramming tool, the
Tech 2 can be dedicated to diagnostic applications.

COMMON CONNECTORS AND COMPONENTS
Whey you purchase a Tech 2, you will find that it comes with many cables, components, and
connectors. The most critical pieces that you will use most are the Tech 2 itself, the data link
cable, the OBD II connector, and for the newer vehicles the CANDi module.
GETTING STARTED
The Tech 2 is ready to go right out of the box. There is a 32 MB data card inside of the tool that
has software already pre-loaded onto it. It may not be the most current software available, but it
will be ready to start working on vehicles.
The first thing you will want to do is make the cable connections to the tool and to the vehicle
that you will be working on. Connect the data link cable to the Tech 2, then the OBD II connector
to the data link cable. Once you have the tool connected to the cable, locate the data link
connector on the vehicle and plug the data link cable into the vehicle connector.

Power Up And Display
The [PWR] key is used to turn the Tech 2 on or off. The status indicator light above this key is
illuminated green when the Tech 2 is operational.
The [SHI T] key is used with the up and down arrow keys to change screen brightness and
contrast.
To adjust screen brightness and contrast, perform the following:
1. Press the [SHI T] key once (amber status indicator light above [SHI T] lights up).
2. Use up and down arrows to adjust screen brightness and contrast.
3. Press [SHI T] key again when desired brightness is reached (status indicator light above
[SHI T] is off).
The Tech 2 should return to normal operation after following the above steps.

You may have noticed that when you purchased your Tech 2 that a manual was not included.
This is because they want you to have the latest version of the manual. The manuals for the Tech
2 can be found online at:
http://www.boschdiagnostics.com/support/documentation/Pages/DiagnosticsDocumentation.a
spx?type=UnderHood
Once you have pointed your browser to the website, you can use the drop down menu in the
middle of the screen to select the tool that you want to download the manual for.
HOW TO IND THE ONLINE MANUALS
rom there you will see all of the available downloads for the tool that you have selected as well

A common question that technicians ask when starting to use the Tech 2 is: “How often or when
should I update the tool?”.
When you power up the Tech 2 the first screen that shows up on the display indicates what
software version is loaded on the tool.
The software download function of TIS 2000 is used to update Tech 2 Scan Tool software to the
latest version. Like all computers, the Tech 2 scan tools each store software that determine how
they run and what they can do. This software allows the scan tools to perform diagnostic routines
on or for the following vehicle applications: Powertrain, Body, Chassis, and Service Programming.
Scan tool software is regularly updated to reflect changes in vehicle engineering or diagnostics.
Updates can include:
• New vehicle system coverage.
• Improvements to diagnostic procedures.
• Updates to original application releases.
• The addition of new diagnostic procedures.
Tech 2 software is stored on a Personal Computer Memory Card Industry Association (PCMCIA)
card. The contents of the card are not distinct applications as is the case with certain Tech 1
cartridges.
All of the applications share a single database
of information on the Tech 2's PCMCIA card.
The PCMCIA card is accessed through a door
on top of the unit, and should only be removed
if instructed by the Techline Customer Support
Center.
The card is ejected by pushing the arrow button
pointing to the card to be removed. Cards are
notched to allow insertion only one way. When
reinserting the card make sure that it fully
seats into the Tech 2. The PCMCIA card fits into
slot “zero” which is closest to the screen.
A second slot exists for non North American
Operations (NAO) vehicle software. The second
slot is identified as slot “one.”

SETTING UP TECH2 VIEW (T2 VIEW)
Most of you will be using the Tech 2 in a stand alone mode. or demonstration purposes, we will
show you how to set the Tech 2 up to be viewed on a larger screen. To do this we need to
connect the Tech 2 to the PC as described earlier in this presentation, and we also need to log
into the Tech2 View (T2 View) option at the TIS2Web website.
Once we have logged in you will be prompted to load the Java platform. Once the Java platform
has been loaded, a screen will appear on your PC that will emulate the screen of the Tech 2.
Next, click on the “connect” icon at the top left corner of your PC screen and follow the prompts
on the screen.
Once you have established a communication link with the Tech 2, you should see a screen that is
similar to the screen capture below.
