SERVICE PROGRAMMING SYSTEM (SPS)
The procedure to program the control unit by using Service Programming System (SPS) software contained in TIS
2000 is explained in steps below.

Important: Perform the following checks before attempting to program the control unit:







The Tech 2 PCMCIA card is programmed with the latest software release.







The latest release of TIS2000 is located on the PC.







The vehicle battery is fully charged.







The control unit to be programmed is connected to the vehicle.

1. Preparations of TIS 2000
1. Connect Tech 2 to P/C.
2. Check to see if Hardware Key is plugged into Port.
3. Activate TIS 2000 by P/C.
4. On the activating screen of TIS2000, choose "Service Programming System"



5. On the screen of "Diagnostic Tester and Processing Program Selection", choose the one that will comply with
the following.

Diagnostic Tech2 in use

New programming by the existing module or new programming by the replaced/new module.

Fixing position of the control unit.
6. Upon completion of the selection, push the button of "Next".


2. Demand of Data
1. Connect Tech-2 to the vehicle. When activated by turning on the power of Tech-2, push the "Enter" switch.
2. Turn on the ignition switch (without starting the engine).
3. In the main menu of Diagnostic Tester, push "F1: Service Programming System (SPS)".
4. Push "F0: Request Info" of Tech-2.
5. Where vehicle data has been already saved in Tech 2, the existing data come on display. In this instance, as Tech-2 starts asking whether to keep the data or to continue obtaining anew data from the control unit,
choose either of them.

7A2-22 DIAGNOSIS (JR405E)


6. If you select “continue”, you have to select “Model Year”, “Vehicle Type”.
7. After that, push button and turn Ignition switch tuned on, off, on following Tech-2 display. Tech-2 will read
information from controller after this procedure.
8. During obtaining information, Tech-2 is receiving information from the control unit ECM and TCM at the same
time. With VIN not being programmed into the new control unit at the time of shipment, "obtaining
information" is not complete (because the vehicle model, engine model and model year are specified from
VIN). For the procedure get additional information on vehicles, instruction will be provided in dialog form,
when TIS2000 is in operation.
9. Following instructions by Tech-2, push the "Exit" switch of Tech-2, turn off the ignition of the vehicle and turn
off the power of Tech-2, thereby removing from the vehicle.


3. Data Exchange
1. Connect Tech-2 to P/C, turn on the power and click the "Next" button of P/C.
2. Check VIN of the vehicle and choose "Next".
3. Select “Transmission” in the “System Type” selection.
4. When a lack of data is asked from among the following menu, enter accordingly.
Select following Menu

Model Year

Model

Engine type

Destination code (vehicles for general export)*1

* 1: How to read the destination code:
Destination code can be read from service ID Plate affixed on vehicle, while on service ID Plate the destination
code is described at the right-hand edge of Body Type line. In the figure, the destination code can be read as "RR3"
for Australia.

DIAGNOSIS (JR405E) 7A2-23


4. After choosing the data, click the "Next" button.
5. When all the necessary information is entered, the "details" of software within the database that match the
entered data will appear for confirmation. Click the "Program" switch and then download the new software
onto Tech-2.
6. "Data Transfer" comes on display. The progress of downloading will be displayed on the screen in the form of
bar graph.
7. Upon finishing the data transfer, turn off the power of Tech-2, removing from P/C.


4. Programming of TCM
1. Check to see if batteries are fully charged, while ABS connectors shall be removed from the vehicle.
2. Connect Tech-2 to Vehicle Diagnostic Connectors.
3. Turn on the power of Tech-2 and the title screen comes on display.
4. Turn on the ignition (without allowing the engine to start)
5. On the title screen of Tech-2, push the "Enter" button.
6. Choose "F1: Service Programming System" on the main screen and then choose "F1: Programming ECU".
7. While data is being transferred, "Programming in Progress" will be displayed on the Tech-2 screen.
8. Upon finishing the data transfer, Tech-2 will display "Reprogramming was Successful". Push the "Exit" button
to bring program to completion.
9. Following "Procedure 2: Demand of Data", try over again "Information Obtaining" and check to confirm if the
data has been correctly re-loaded.
10. Upon finishing confirmation, turn off the ignition of the vehicle and then turn off the power of Tech-2,
removing from the vehicle.
