from those displayed for the vehicle being tested.
2. PROGRAMMING TECH 2
2.1 GENERAL INFORMATION
Before Tech 2 can be used on a vehicle it will have to be
programm ed with the lates t software. Tech 2 pr ogramming
is used to update Tech 2. TIS 2000 contains the current

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 com pute r has a 25 pin s er ial c omm unic atio n
port you will need to fit the 25/9 pin adapter between the
nine pin DB-9 adapter and the serial communication port.

3. 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.
3.1 CONNECTING TECH 2 TO THE VEHICLE
1. Connect Tech 2 (A) to the vehicle DLC , with the DLC
cable and the 16/19 pin adapter.
2. Switch th e unit on b y pres sing 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 sh ould find most c ommon 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 w ill brie fly sh ow the P OST 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 POS T will allow continued use of the TECH 2, but wi th
some limitations. If either a fatal or non-fatal error occurs,
refer to the Troubleshooting section of the TECH 2 User's
Guide.
