k. A Calibration Selection screen appears showing the calibration file history for the vehicle/controller 
being serviced. There are explanations of each calibration file. Based on the descriptions, select the 
appropriate file. 
• Vehicles with PCMs display a screen similar to the one shown in Figure 8-25. 
• Vehicles with VCMs display a screen similar to the one shown in Figure 8-26. It contains multiple 
“tabs”—one for each distinct calibration file contained in the VCM. With these vehicles, it is 
necessary to make a selection within each tab, otherwise the system displays the message shown in 
Figure 8-27, indicating that not all selections have been made (notice the unchecked box in the 
system tab). 
The following icons appear on the calibration selection screen(s): 
• A circle with a slash indicates a file that is not selectable. 
• An open box indicates a file that is selectable. 
• A box with a check mark indicates a valid file/option that has been selected. 
• If service bulletins are listed along with the calibration files, the bulletins should be referred to before 
service programming is performed, then select Next. 
l. After making the necessary selections, a Summary screen appears (Figure 8-28) allowing you to 
confirm your selection. Select Next to continue. 
m. A Transfer Data screen appears (Figure 8-29). Select Reprog to initiate the download of the new 
calibration file to the Tech 2. 
The screen tracks the progress of the download. 
After the download is complete, a screen appears with instructions for connecting the Tech 2 to the 
vehicle to complete the programming process (Figure 8-30). 
n. Close the application to return to TIS 2000, then power down and disconnect the Tech 2 from the PC.

VERIFYING REPROGRAMMING 
After any kind of control module programming, verify that programming was successful. Turn the ignition 
off, wait at least 30 seconds, then start the vehicle to confirm that reprogramming was successful. If the 
vehicle does not start or starts but runs rough, repeat the SPS procedure. 
Former versions of this manual included Figure 8-31 and Figure 8-32. These features are no longer relevant. 
SOFTWARE DOWNLOAD 
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/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. 
NOTESome vehicles require that Idle Learn, TP Learn, Theft Deterrent Relearn, 
or Crankshaft Variation Learn procedures be performed after 
programming. Consult the appropriate service information for these 
procedures.

PCMCIA Card 
Tech 2 software is stored on a Personal Computer Memory Card Industry Association (PCMCIA) card 
(Figure 3-8 and Figure 3-9). 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 2s 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 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.” 
A write-protected slide mechanism is on the top edge of the card under a white plastic CPA-type device. The 
correct position is to the middle of the card (unlocked). If the write protect is in the locked position, 
snapshots and Capture Info. cannot be stored, and Service Programming does not work. 
TECH 2 UPDATE PROCEDURES 
The Software Download function of TIS 2000 allows updating of the Tech 2 with the latest service 
information. The Software Download function transfer (downloads) updated scan tool software from the 
terminal to the scan tool. There are two download modes: Standard and Custom. 
Standard Update 
To perform a Standard Tech 2 update: 
1. Connect the scan tool to the terminal using the RS-232 cable (Figure 8-20). 
2. Power up the scan tool using the AC power supply that came with the tool (refer to Figure 8-20). 
3. At the terminal, start TIS 2000. 
4. From the TIS 2000 main screen, select the Software Download icon (refer to Figure 8-18). 
5. At the Select Diagnostic Tool for Download screen, highlight and verify your selection (Figure 8-33). 
• Standard installs the newest software onto the scan tool. 
• Custom allows backdating or installing of non-NAO software onto the scan tool. 
6. After confirming the selection, select Next. 
A message appears indicating the terminal is reading the contents of the diagnostic tool. 
7. The terminal displays a Confirm Software Change screen (Figure 8-34) showing what the Tech 2 
currently contains and what it will contain after the download. Select Next to continue. 
NOTE
The PCMCIA card is sensitive to magnetism and static electricity. USe 
care when handling.

SNAPSHOT UPLOAD 
The Snapshot Upload function of TIS 2000 provides a means for viewing scan tool snapshot data, as well as 
freeze frame and capture data info on the terminal. This data can be analyzed in a variety of ways to 
determine when and where a fault may have occurred. 
Using the Snapshot display feature involves three steps: 
1. Capture snapshot(s) with the scan tool. 
2. Upload the snapshot(s) to the terminal. 
3. View the snapshot(s) using the TIS 2000 Snapshot Upload function. 
To Capture a Snapshot of the Vehicle Data Stream:
1. Connect the Tech 2 to the vehicle Data Link Connector (DLC). (Refer to Tech 2 Connection to PC on 
page 3-17.)
2. Power up the Tech 2 and enter vehicle information as requested on the scan tools display. 
3. From the Application Menu, select F3: Snapshot. 
4. At the next screen, select the desired system to snapshot (e.g., engine, transmission). 
5. At the next screen, select the desired data list (e.g., engine 1, engine 2). 
6. At the next screen, select the trigger type and trigger point. 
Trigger Type (F0-F3 function keys) determines how the snapshot is triggered: 
•F0: Manual Trigger triggers a snapshot when you press the Trigger soft key. 
•F1: Any Code triggers a snapshot whenever any current trouble code is stored. This event occurs 
when the first code is stored in the vehicle controller memory. 
•F2: Single Code triggers a snapshot when a user specified trouble code is stored.
