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

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 GM 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):

1.An Application CD which loads the SPS application
2.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

Note: If the Car Scanner 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.

29-4

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

29-5

4 Click the Next button. This displays the Choose Serial Port window

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.

29-6

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.

29-7

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

29-8

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 supported.

29-9

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).

29-12
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. 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 computer.

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.

Customer real experience with GM Tech 2 Scanner (Review)

23-1

Here is the my real experience on gm tech 2 Scanner from obd2tool.com

Bought the highest quality version as i didn’t want to risk any issues with the device, and it all works fine and i do not regret my purchase.

It arrived pretty fast, but i got a £17 customs charge which i didn’t realise i’d get.

First impression: the carry case is not the one shown in the photo’s, which is annoying as the one in the photo’s looks really good, With the cables and candi module stored underneath 2 flaps, the main unit and adaptors clipping in the top of the case etc.

What i got was a basic plastic case (with sharp metal catches) where everything is squashed in on one level in foam, it does the job i guess, but i’d really have prefered the better case i thought i was paying the extra £30 for.

I’d bought a genuine Ugreen rs232 to usb cable in advance, £10 off amazon, this is one of the few cables listed as working with the tech2, and it did, connects at highest speed with no issues at all.

The house power supply has an american plug on it (psu has a universal voltage of 100 to 250 volts)
i got worried when the tech ii scanner wouldn’t even turn on, then i noticed the plug had slightly pulled out of the adaptor i had to use, something we are not used to in england as our plugs fit the sockets very securely and are hard to accidentally pull out, so changing the plug is one of the first things to do…
The house psu runs pretty warm btw.

I did all the self tests and it passed them all with flying colours (except the usual HBCC test that gets ignored (used on some ford vehicles i believe) and the RS485 that has no loopback adaptor so will always fail)

I took it out to my car (a 2011 vauxhall meriva B) and plugged it in, it connected straight away and i asked it to give me a list of DTC’s, i had been using an op-com before i got the Tech2 and the tech2 listed some old DTC’s the op-com had never picked up, I cleared the DTC’s, then tried the rest of the diagnostics available, i had no problems so far, i was able to move engine actuators (op-com can’t do that on the meriva B) operate things remotely, saw the DPF was at 108% full, so went for a little drive and the tech2 showed the DPF regen in progress, got an exhaust temp of 650 degrees C during it)

However that test drive showed up the universal weakness of the clone tech2’s, the internal power supply cuts out when you start the engine so the tech2 re-boots, this means there are a few diagnostic tests you can never do that involve starting the engine whilst the tech2 monitors things (unless you use external power to the tech2, which is advised against in all service manuals)

There is a solution, replace the internal power supply module with a better quality unit!!

There is also a highly recommended modification of removing the RS232 chip and putting a usb module in it’s place so you have a direct USB connection to the tech2, rather than the 4 connections that are just begging to be caught and pulled apart whilst uploading software to the car.
These mods are on the tech2 wiki (google it)

I then tried to SPS to my car to add a new IPC… one of the reasons i bought the Tech2.

That’s when discovered my car is not in the list of cars you use the tech2 to service program directly (the: connect tech2 to car, download data, take tech2 to computer, upload data, download software update, take tech2 back to car and upload the software method)

But i figured i could SPS using the tech2 in the J2534 pass thru mode… only my computer couldn’t connect to the tech2 in that mode… remote view of the unit worked but not SPS… i figured the issue out tho…
The rs232 to usb adapter had been assigned to com port 7 when i plugged it in, i changed the com port to COM1
~windows / computer / device manager / ports (COM & LPT) and find the relevant port your rs232 adapter is on (it wont be listed as ‘Tech2’) and change it to port 1~

Now SPS in pass thru mode works perfectly, i updated the software in a few of the modules (i use GlobalTis 32b, the last offline version with full SPS capability, was released in 2012 i believe, and it had newer software than my 2011 car had in it)

Then i did an update of the BCM and IPC to allow the rain sensor i’d just wired in to be seen by the systems, I tried to add a new immobilizer key, but it refused the accept the new key, most likely the key is at fault.. as part of learning new keys is to delete the old ones from the system, and the tech2 added them back no problem.

I’ve also used the tech2 to connect to ford vehicles using some software called ‘ForScan’ it has the Tech2 listed as a J2534 pass thru devise and works fine with it, The pcmcia card that came with the Tech2 allowed it’s self to be re-written (some people buying from other places find the card is locked and can’t be re-written)
i used GlobalTis’s card writer feature, it takes 40 minutes to write the card, but it works fine.

I’m very pleased with my Tech2 so far, the only thing that would make it perfect would be the carry case that’s shown in the photo’s, but that dosent affect how the actual devise works.

I’d recommend anyone buy their gm tech 2 scan tool from this shop, and i have pointed a few people who were interested in buying one here.
