1 General Information
With the following exceptions, MY 2004 WK Series TECH 2 information carries over from MY 2003 VY Series vehicles.
For information not contained within this Section, refer to Section 0C TECH 2 in the MY 2003 VY and V2 Series Service
Information.
• Body Control Module (BCM)
• Multi Function Display (MFD).
• Premium Sound Amplifier (PSA)
• Audio Interface Module (AIM).
• DVD Player.
• Seat and Exterior Rear View Mirror.
1.1 Using TECH 2 On The Vehicle
Connecting the TECH 2 to the Vehicle
The following TECH 2 screen displays may very with different applications and versions of TECH 2 software.
1 Connect TECH 2 (4) to the vehicle DLC (1), with the
DLC cable (3) and the 16/19 pin adapter (2).
Figure 0C-1 Connecting the TECH 2 to the Vehicle
TECH 2 Page 0C–3
Page 0C–3
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.
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.

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.
