The Status displayed on the EASE SPS Software Utility says “Bad Firmware” or “SPS Low Batt” what do I do?

The “Bad Firmware” status means that the firmware stored onboard the unit is corrupt, probably due to a low internal battery. The “SPS Low Batt” status means that the battery voltage on-board the SPS unit is low and needs to be replaced. For both of these conditions, you need to replace the battery and reload the firmware on the unit. Follow the instructions below.

  1. Locate the spare battery for the SPS unit. One was included with your original package. The battery type is CR1225 3.0V/48 mAh Lithium battery.
  2. Disconnect all cables that are connected to the SPS unit.
  3. Use a 3/16” nut driver to remove the two hex-headed screws next to the DB25 connector on the “Vehicle” endplate of the EASE SPS unit.
  4. Use a Phillips screwdriver to remove the two screws from the PC (DB9) endplate.
  5. Grab the bezel on the PC end and slide the circuit card out a few inches.
  6. Remove the battery and put the new one in.
  7. Slide the card back in the case and install the screws into both the endplates
  8. Connect the Serial Interface Cable to the PC DB9 port on the SPS unit and the PC’s COM port.
  9. Power the SPS unit by plugging the AC adapter into the unit and a power source.
  10. Start the EASE SPS Utility Software.
  11. Click the Update SPS Firmware button.
  12. On the Step 1 tab of the SPS Firmware Update Screen, click the Select File button. The Open Screen will be displayed. In this screen, select the desired firmware file.

SPS Reprogrammer - GM TIS 2000 Reprogramming Questions
I've just received my new hardware lock, but I get an error message saying that there is no hardware key found when I run the software. What do I do?

  • Be certain to verify that you have the latest version of the TIS 2000 Installed on your computer. (Version 2.4) If not, be certain to contact EASE to obtain the latest version.
  • Be certain to use the prompts during the installation of the program, as to which hardware key you have. If you choose the wrong key, the incorrect driver for that key will be installed, and the TIS 2000 software WILL NOT OPERATE. If you already have the latest version, and have obtained a new hardware key, the TIS 2000 program will need to be un-installed, and re-installed. This is necessary to load the appropriate driver for the hardware key that you have.

I run the EASE SPS Utility which starts the TIS 2000 software. The Preparing for Communication screen in the TIS 2000 software states ‘Connect Tech 2 to vehicle’ but I don’t have a Tech 2. In fact, Tech 2 is mentioned several times in the TIS 2000 software. Do I need a Tech 2?

No, a Tech 2 is not required with the EASE SPS. The General Motors TIS 2000 software is made to use with their Tech 2, but when used in conjunction with the EASE SPS Utility and hardware unit, the Tech 2 is not needed. Replace Tech 2 in the instructions with the EASE SPS hardware unit.

I run the SPS EASE Utility and connect to the COM port fine, but when the TIS 2000 software starts, it can’t find the VIN number when connecting to the vehicle. What is wrong?

The correct COM port may not be selected in the TIS 2000 software.

  • If your TIS 2000 Application Version is prior to 1.05: Make sure the serial interface cable that is connected to the EASE SPS unit is plugged into to COM 1 (serial port) on the PC. Prior to version 1.05, the GM TIS 2000 software, will only communicate with COM 1 even though it lists multiple COM port selections.
  • If your TIS 2000 Application Version is 1.05 or higher: Make sure the correct COM port number is selected in the TIS 2000 software. To change the COM port number in the TIS 2000 software, select Configuration\ I/O Management from the software menu bar. Select Pass Through Properties and then select the COM port that the SPS is connected to. It should be the same COM Port number that you selected for the EASE SPS Utility.

I run the EASE SPS Utility and connect to the COM port fine, but when the TIS 2000 software starts, a message is displayed that states it can’t find the hardware key. What is wrong?

  • The hardware key (GM Security Interlock) must be on the 25 pin parallel (printer/LPT) port. Ensure that the hardware key is NOT on a 25 pin serial port.
  • It’s possible that the processor in the PC does not meet the minimum requirements. The processor needed for the TIS 2000 software to run properly is a Pentium 166 MHz processor (or greater). No other types of processors are supported. Refer to the minimum system requirements.
  • A computer that is 650 MHz or faster may require a patch file installed in order to see the hardware lock. Version 1.61 of the EASE SPS Utility has the patch file located on the installation CD in a folder called Hardlock. See the Readme.txt file in the Hardlock folder for more information on loading the patch file. If you have a previous version of the SPS Utility, contact EASE for the patch file. Note: Only load the patch file if you get the error message stating it can’t find the hardware key.
  • The software is loaded on a Laptop Computer. Laptops are not supported, only desktop PCs. Refer to the minimum system requirements.
  • If none of the above is the problem, contact tech support for assistance.

I get an ‘Ignitions/Battery Voltage Too Low’ error when I try to reprogram a controller off-board, yet I can program the same controller on-board (in the vehicle). What could be wrong?

The power adapter used to power the SPS hardware unit must have an output of 12 Volts and 1.5 Amps (or 1500 mA). A power adapter with an output or 0.5 or 1.0 Amp is not adequate to power the unit.

I’m getting an error I don’t understand in the TIS 2000 software. What should I do?

  • If you are programming the controller off-board and the error is Ignition/Battery Voltage Too Low, ensure that the power adapter you are using to power the SPS box has an output of 12 Volts and 1.5 Amps (or 1500 mA).
  • If you are getting an error that says it cannot find the VIN and you are using something other than COM Port 1, ensure that you have changed the COM Port number in the TIS 2000 software.

I’m reprogramming an OBD II Saturn controller on-board and the TIS 200 software displays a message about using the Red Tech 2 connector. I only have a black OBD II connector, what do I do?

The Saturn needs a special DLC cable with the Tech 2 as the power requirements are different. The EASE SPS Utility accounts for this power difference so no special cable is needed. Use the EASE DLC cable as always when reprogramming OBD II on-board vehicles.

Do I need to run the EASE SPS Utility Software to reprogram a controller?

Yes, the EASE SPS utility MUST be used to reprogram a controller using the EASE SPS Reprogramming unit. There is a TIS 2000 icon on the desktop, but this is only to be used when installing Data CD updates. When reprogramming a controller, the EASE SPS utility must be used which will start the TIS 2000 software at the appropriate time.

I just finished reprogramming a controller and now the vehicle starts but then stalls. What is wrong?

You must run the Theft Relearn procedure. For more information on relearn procedures, run the EASE SPS Utility and from the menu select Info and then select Controller Relearn Procedure to find the applicable procedure.

I just finished reprogramming a controller and the software states that I need to perform a Crankshaft Relearn Procedure. How do I do it?

For information on the Crankshaft Relearn Procedure, run the EASE SPS Utility and from the menu select Info and then select Controller Relearn Procedure to find the applicable procedure.
