How to use Tech 2 for Service Programming System (SPS)

car diagnostic tool

GM Service Programming System manual:

The GM Service Programming System (SPS) is a personal computer (PC) application used to reprogram vehicle electronic control modules (ECMs). The SPS application programs General Motors programmable control modules by using the Tech 2 Flash scan tool or the Next Generation scan tool as a “pass-thru” device to communicate program data to the vehicle control module. All programming steps are activated and finalized through the PC

Service Programming System software CDs

GM Service Programming System kit contains two compact discs (CD):

  • An Application CD which loads the SPS application
  • A Data CD which loads SPS data

System Requirements


SPS application install

Step 1: Determine if TCP/IP protocol is installed

– If you have a network card installed then you only need

to verify that TCP/IP protocol has been configured.

– If your PC is already set up with TCP/IP protocol, go to

“Install the SPS Software”

Step 2: Install the SPS Application CD software

To install the SPS software, follow these steps:

1 Insert the Application CD into the PC’s CD drive.

The TIS 2000 Installation Welcome window appears automatically

(Figure 1.8).

Note: If the TIS2000 software was previous installed and

removed from the PC, a message may appear asking to

reuse old settings. If so, click the NO button to NOT reuse

old settings.


2 Click the Next button to continue. This displays the Language Selection window.


3 Select a language for the application and then click the Next button. This displays the Choose Destination Location window.


4 Click the Next button. This displays the Choose Serial

Port window (Figure 1.11).

Note: Clicking the Next button on the Destination

Location window places the SPS application in the

destination directory C:\Program Files\cosids. You can

optionally click the Browse button to select a different

destination directory for the files.


5 Select the serial port to use for the scan tool connection. This must be an open COM port where no external devices are connected. Then click the Next button. This displays the TIS2000 Installation Mode window.


6 Select Standalone and then click the Next button. This displays the Set DEALERSHIP window.


7 Select NAO (North American Operations) and then

click the Next button. This configures settings, starts the

Decurity Device Installation module, and displays the

TIS2000 Security Device Add / Remove window.

Note: This installation of TIS2000 supports reflash of

Saturn vehicles. Other dealership installations are not



Note: The Security Device Installation module configures the USB security key, which is a component of the SPS Kit. The installation of the USB security key requires strict attention or TIS2000 will not perform as expected.

8 Click the checkbox above USB Security Key to place a checkmark in the box (Figure 1.14). Then click the Continue button. This displays an Information window (Figure 1.15).


9 Follow the instructions on the Information window and then click the OK button. This displays a Hardware Installation message box.


10 Click the Continue Anyway button. This displays the Program Completed window.


11 Install the purple USB security key as instructed on the

window and then click the OK button.

Note: Make sure the security key installs securely into

the PC’s USB port. After installing the software, do not

remove the security key from the USB port; it must remain

in the port for the TIS2000 SPS application to work.

12 This begins the TIS2000 software installation and

displays a progress indicator message (Figure 1.18).

Wait for the installation to complete and for the completion

message to appear (Figure 1.19).

13 Click the OK button.

14 Remove the Application CD from the PC’s CD drive.

15 Go to Update the SPS Data

Step 3: Update the data with the SPS Data CD

Note: During the update, the TIS2000 software skips the initial language, dealership, etc. steps and uses current TIS2000 settings. TIS2000 also skips over SecDevIns (Security Device Installer) and uses the current TIS2000 settings.

1 Insert the Data CD into the PC’s CD drive and wait approximately

20 seconds for the TIS2000 Update message to appear.

Note: On Windows XP systems, a browser window may

open displaying the contents of the CD. If so, close the

window and double-click the TIS2000 icon on the

Window’s desktop. Because TIS2000 looks for new

updates each time you start the application, the Update

message appears.

2 Click the OK button to continue. This begins the update and displays a progress indicator message. When the update completes, a completion message appears

3 Click the OK button. The application is ready to use.

4 Begin using the SPS application by double-clicking the TIS 2000 icon located on the Window’s desktop.

Service Programming Cautions

CAUTION: There are a number of programming

preparations that must be followed exactly or permanent

damage to a reprogrammable control module

could result:

  • Battery voltage– The battery must be between 12.6 and

14 volts. The battery must be completely charged before

programming. Important: Do not program while charging

the battery. Connecting a second battery in parallel

to the vehicle battery helps prevent drawing the battery

charge low enough to cause a fatal error to the vehicle

ECM while programming.

  • Ignition key on, engine not running – One of the PC

message screens requests that the ignition key be turned

on, engine not running. Important: Do not turn the key

to any other position until the programming is complete.

Once programming is complete, turn the ignition

key off, wait about 30 seconds, and then disconnect the

tools. This allows time for the vehicle computer to power

down properly.

  • Power interruption– Important: During programming,

do not interrupt power or DLC connections in

any way. This could cause permanent damage to the

reprogrammable control module. Before programming,

check all connectors and cords for wear, and check all

connections to be sure they are secure. All cords must be

properly routed and secure to prevent any entanglement

with feet or hands.

  • Tampering– A new control module is not preprogrammed.

The memory of an in-use reprogrammable

control module contains the vehicle identification number

(VIN) as well as calibration data. In the course of reprogramming

an in-use control module, the VIN and the

calibration date are replaced. The VIN entered into the

scan tool must match the VIN on the vehicle’s VIN plate.

It is important that the correct VIN be installed in the control

module for future service and in the event of a recall

campaign that requires reprogramming the module. Other

information entered into the program must also be correct.

Programming improper calibration data could adversely

affect vehicle exhaust emissions resulting in violation of

emission control laws and regulations.

  • Self-starting computer applications – ALL personal

computer applications must be turned off before you use

the SPS application. A screen saver, virus detection application,

network connections, or any other applications

that can activate without user prompting must also be

turned off to prevent any disruption in communication.

Any disruption during the reprogramming function can

cause a programming failure and damage the vehicle


  • Current drain – Headlights and fans may be activated

during the reprogramming steps. This can cause enough

current drain to the battery to bring the battery voltage

below an acceptable level for programming, or low

enough to damage the vehicle computer. Set the parking

brake to disable “automatic on” headlights. Remove the

fuses for high current body electronic circuits, but do not

remove the fuse for the vehicle computer circuit.

  • Doors may lock– During programming, leave a window

open to enable access into the vehicle.
