General Information
The Tech 2 is a hand-held diagnostic computer which has been designed specifically to help Dealership Technicians
diagnose and repair the electronic systems used on Holden vehicles.
NOTE: Due to the constant evolution of TECH 2 software, the screens shown in this section may differ slightly
from those displayed for the vehicle being tested.
Programming TECH 2
General Information
Before Tech 2 can be used on a vehicle it will have to be
programmed with the latest software. Tech 2
programming is used to update Tech 2. TIS 2000
contains the current Tech 2 applications (program) and
one preceding version. Tech 2 can be programmed
using the following procedure.
1. Connect the RS-232 (1) cable to the Tech 2 RS-232
communication port.
2. Connect the other end of the RS-232 cable to the
DB-9 adapter and then connect the DB-9 adapter to
the serial communication port of your computer.
NOTE: If your computer has a 25 pin serial
communication port you will need to fit the 25/9 pin
adapter between the nine pin DB-9 adapter and the
serial communication port.
3. Connect the AC power supply to the Tech 2 power
jack.
4. Press the PWR button to turn on Tech 2.
5. From the TIS 2000 Main Menu, click on the
Software Download icon.
There are two download modes: Standard and Custom.
Standard installs the latest software version of the
currently programmed language and make onto the
Tech 2.
Custom allows you to perform backdating, install
different make software or alternate languages onto the
Tech 2.
Standard Update
The procedure for performing a standard Tech 2 update
using the TIS 2000 Software Download is as follows:
1. Connect the Tech 2 to the PC using the RS-232
cable, DB-9 adapter and the 25/9 pin adapter if
required.
2. Power up the Tech 2 using the AC power supply
that comes standard with the Tech 2 kit.
Tech 2 must be at the Title Screen.

After making your selections, click Next>. A message
will appear indicating the PC is reading the contents of
the diagnostic tool.
4. The PC will display a Confirm Software Change
screen showing what software version the Tech 2
currently contains and what it will contain after the
software download. Click Next> to continue.
5. A Performing the Software Download screen will
appear. It tracks the status of the software
download.
6. When the software download is complete, a
Download Finished screen appears. Click on Close
to close the application. The scan tool now contains
the latest software.
Custom Update
A custom update is used to backdate the TECH 2,
install Non-Holden software or install different language
software. After selecting Custom as the update mode
from the selection screen, do the following:
1. Connect the TECH 2 to the PC using the RS-232
cable (1), DB-9 adapter and the 25/9 pin (2)adapter
if required.
2. Power up the Tech 2 using the AC power supply (3)
that comes standard with the TECH 2 kit.
Tech 2 must be at the Title Screen.
3. At the TIS 2000 Select Diagnostic Tool for
Download screen highlight your selection (TECH

Using Tech 2 On The Vehicle
NOTE: Due to the constant evolution of TECH 2
software, the screens shown in this section may
differ slightly from those displayed for the vehicle
being tested.
Connecting TECH 2 To The Vehicle
1. Connect Tech 2 to the vehicle DLC, with the DLC
cable and the 16/19 pin adapter.
2. Switch the unit on by pressing the power button (2).
A green light (1) should come on indicating that the
tool is receiving power.
NOTE: At this time the technician should see the Power
On Self Test (POST) run. The POST is a built in
diagnostic self test for the TECH 2 that should find most
common system faults. The POST is run on every
power up to ensure the best operation of the tool. After
the completion of the POST, the TECH 2 unit will briefly
show the POST results. If POST passes, the tool will
continue onto the title screen. If POST fails, results of all
tests will be displayed, and this should show which test
failed. POST failures may be classified as fatal or non-
fatal. A fatal error will not allow the user to continue
using the tool. Failure of the keypad would be an
example of a fatal error. Non-fatal errors found during
the POST will allow continued use of the TECH 2, but
with some limitations. If either a fatal or non-fatal error
occurs, refer to the Troubleshooting section of the
TECH 2 User's Guide.

4. A selection can be made from the Main Menu,
either by using a function key or by using the arrow
keys to highlight a menu choice and pressing
ENTER.
•NOTE: You will then need to supply some additional
information to the TECH 2. This requires navigation
through a series of lists (called picklists). On some
menus or picklists, the user can use a function key to
make a menu selection, but most of the picklists
require using the selection and action keys. If a
mistake is made in the selection process, or if a
different application or function is desired, press EXIT
to back up one level. Within an application, there may
be soft keys which are available for use. These soft
keys allow access to additional tool functions without
exiting a current tool function. Soft keys are made up
of sets which will appear together. To see the next set
of soft keys, select the More soft key.
The TECH 2 Main Menu contains the following:
F0: Diagnostics
Contains all functions to test, diagnose, monitor and
program the different vehicle systems.

F0: Diagnostic Trouble Codes
In this test mode, DTCs stored by the PCM can be displayed or cleared. When F0: Diagnostic Trouble Codes is
selected, there are an additional four modes:
F0: Read Current DTC: All current DTC(s) will be displayed.
F1: Clear Current DTC: Clears all current DTC(s) in the PCM memory.
F2: DTC Information: All current DTC(s) will be displayed in numerical order.
F3: Freeze Frame/Failure Records: Freeze Frame is an element of the Diagnostic Management Ssytem which
stores various items of vehicle information at the moment an emissions related DTC is logged in memory and
the MIL is commanded ON.
Failure Records data is an enhancement of Freeze Frame. Failure Records store the same vehicle information
as Freeze Frame, but will store the information when DTC is logged in memory.
F1: Data Display
This mode displays data parameters for the system being diagnosed. When entering this mode, there are three
modes:
F0: Engine Data: In this test mode, the TECH 2 continuously monitors and displays all engine data parameters.
F1: Misfire Data: In this test mode, the TECH 2 continuously monitors the PCM’s “mis-fire counters”. A current and
history misfire counter are maintained for each cylinder. Engine data parameters relevant to the misfire are
displayed along with the misfire counters.
F2: O2 Sensor Data: The Tech 2 continuously monitors and displays engine data parameters.
F2:Snapshot
In this mode, the TECH 2 scan tool captures data before and after a selected snapshot triggering condition which may
or may not set a DTC.
F3:Miscellaneous Tests
In this test mode, the Tech 2 performs software override commands of the PCM, to assist in problem isolation during
diagnostics.
F0: Lamps: The MIL (Malfunction Indicator Lamp) can be commanded on and off.
F1: Relays: The A/C Compressor Clutch relay and the Fuel Pump relay can be commanded on and off.
F2: EVAP: The Cannister Purge Solenoid operation can be commanded between 0% and 99%.
F3: Fuel System: Fuel Trim can be enabled or reset and O2 loop status monitored.
F4: Instruments: Tachometer Control allows the basic operation of the tachometer to be tested.
F5: EGR Control: The EGR Valve operation can be commanded between 0% and 99% in 10% increments.
F6: Variable Intake Manifold Solenoid: Used to command the Variable Intake Manifold Solenoid ON and OFF.
F7:Injector Balance Test: Allows individual injectors to be disabled and the resultant drop in engine RPM to be
monitored.
F4:System Information
In this mode, the TECH 2 displays the status of the Malfunction Indicator Lamp (MIL) and the number of emission
related DTC’s set.
