F6: Set Communication By-Pass Mode 
After you select F6: Set Communication By-Pass Mode (Figure 8-10), the screen offers Enable and Disable 
options. By enabling the By-Pass Mode, the Tech 2 bypasses error handling, and allows the user to view 
data display information without being connected to a vehicle. Highlight the desired setting using the up/
down arrow keys, then press ENTER to change the current mode. The Tech 2 defaults to the Disable mode 
once it has been powered off. 
F7: Make Duplicate PCMCIA Card 
This function is used to make an exact duplicate of the current PCMCIA source card. After you select F7: 
Make Duplicate PCMCIA Card, the display prompts you to insert the destination card (the PCMCIA card 
that you want to update) into the open PCMCIA card slot, then press ENTER to continue. The PCMCIA 
Card Duplicator screen (Figure 8-11) appears, showing the current version of both cards. The highlighted 
areas on the screen represent the locations of the source and destination PCMCIA cards. Slot 1 is defined as 
the slot closest to the Tech 2 display. Use the Copy soft key to initiate the duplication process.

TECHLINE INFORMATION SYSTEM 2000 
(TIS 2000)
Techline Information System 2000 (TIS 2000)* is a component-oriented service information delivery 
system that allows technicians to perform SPS, update the Tech 2, and view Tech 2 snapshot data in a 
Windows 95 environment. 
To start TIS 2000, double click its icon in the Techline Information System group on the desktop screen of 
your Techline terminal. TIS 2000 supports service programming with the Tech 2 scan tool only. 
*. At the time of publication, TIS 2000 software available in English only.

SERVICE PROGRAMMING SYSTEM (SPS) 
The Service Programming System (SPS) updates the calibration files that are stored in a vehicle on-board 
controller (e.g., ECM, PCM, VCM). The calibration file custom-tailors a module to a certain vehicle. The 
calibration file contains data for things such as spark curves and fuel control. When troubleshooting a 
driveability problem, diagnosis may call for reprogramming the controller with newer calibration 
information to correct a customer concern.

REMOTE SPS PROGRAMMING 
The Remote SPS method is a three-step process that involves: 
1. Connecting the scan tool to the vehicle and obtaining information from the controller. 
2. Connecting the scan tool to the PC and downloading a new calibration file from the PC to the scan tools 
memory. 
3. Reconnecting the scan tool to the vehicle and uploading the new calibration file to the controller. 
PERFORMING REMOTE SPS 
Important! Prior to performing SPS: 
• Ensure that the Tech 2 and the terminal are both equipped with the latest software. 
• Ensure that the vehicle battery is fully charged. Battery voltage for SPS should be between 12.5 and 14 
volts. However, make sure a battery charger IS NOT connected to the vehicle. 
• Ensure that cable connections are secure. A disconnected cable could cause controller failure. 
Perform remote SPS using TIS 2000 as follows: 
1. Obtain Vehicle Information:
a. With the Tech 2 and vehicle both off, connect the Tech 2 to the vehicle DLC (Figure 3-23). 
b. Start the Tech 2. At the Tech 2 title screen, press ENTER. 
c. Turn the vehicle ignition to on (engine not running). 
NOTE
Battery voltage should be checked. A fully charged battery is necessary 
before reprogramming takes place. The vehicle battery should not be 
connected to a battery charger during a programming event. Incorrect 
voltage could cause programming and/or control module failure. During 
programming, the control module depends on the battery as its sole source 
of power. Also during programming, the vehicles components (i.e. blower 
motor) are set to a default mode which may be turned on, placing 
additional draw on the vehicles battery. If the voltage goes outside the 
specified range (11 to 14 volts) the controllers and the Techline equipment 
stops communicating. If this happens, it could cause the control module to 
become inoperable and require replacement. 
Check the integrity of the Tech 2 cables, make sure they are not frayed, 
broken, or twisted. Loss of communication for any reason requires 
additional time in completing the reprogramming event. 
Do not discontinue or interrupt the program loading process to the vehicle. 
This may result in a programming error and could prevent the vehicle on-
board controller from functioning properly.

d. At the Tech 2 Main Menu, select F1: Service Programming and enter/identify vehicle information as 
requested by the Tech 2. As needed, identify the type of module being programmed. 
e. Press the Request Info soft key on the Tech 2. 
f. At the next screen (Figure 8-19), identify whether an existing module or a new module is being 
programmed. 
For an existing module, the Tech 2 obtains calibration information from the controller. 
For a new module, the Tech 2 instructs you to remove the old module and install the new module in 
the vehicle. When you complete this step, press the Done soft key on the Tech 2. The Tech 2 then 
communicates with the new controller, receiving an access code that enables you to program the 
Tech 2. 
g. Verify that the displayed VIN matches the vehicle VIN, then press Ye s to continue. 
• If the displayed VIN does not match the actual vehicle VIN, write down the actual VIN. You will 
have a chance to input the correct VIN at the terminal. 
h. When complete, press EXIT, power down, and disconnect the Tech 2 from the vehicle. Turn the 
vehicle ignition off. 
2. Transfer Data from the PC to the Tech 2
a. Connect the Tech 2 to the terminal, as shown in Figure 8-20. 
b. At the terminal, start TIS 2000. 
c. From the TIS 2000 main screen (refer to Figure 8-18), select Service Programming System. 
NOTE
Connection location varies depending on terminal configuration.

d. At the Select Diagnostic Tool and Programming Process screen (Figure 8-21) make the appropriate 
selection for your procedure: 
• Under Select Diagnostic Tool, select Tech 2. 
• Under Select Programming Process, identify whether an existing module is being reprogrammed or a 
module is being replaced with a new one. 
• Under Select ECU Location, identify whether on-vehicle or off-board programming is being 
performed. 
e. After making selections, select Next. 
f. A reminder screen appears for making the appropriate connections (Figure 8-22). Select Next after 
confirming connections. 
g. A screen appears, asking to confirm the VIN (Figure 8-23). After confirming/entering the correct 
VIN, select Next. 
A Supported Controllers screen (Figure 8-24) appears asking to identify the type of controller being 
programmed. Some vehicles may have more than one programmable controller-examples include 
PCM, BCM, VDT, IPC. 
h. Select the appropriate controller for the vehicle being serviced. 
i. Identify the type of programming to be performed. 
Normal is used for updating an existing calibration or programming a new controller. 
VCI (Vehicle Configuration Index) is also used for updating an existing controller or programming a 
new controller, but is used for newer vehicles whose VINs arent yet in the database. For these 
vehicles, contact Techline Customer Support, at 1-888-337-1010 for assistance.
Reconfigure is used to reconfigure a vehicle, such as a truck, for changes in tire size and axle ratios.  FIGURE 8-20. Tech 2 to PC Terminal Connection
