6E–84 ENGINE DRIVEABILITY AND EMISSIONS
SERVICE PROGRAMMING SYSTEM (SPS)
The procedure to program the control unit by using the
Service Programming System (SPS) software contained
in TIS2000 is explained below.
NOTE:
• If the Engine Control Module (ECM) was programmed, the Immobilizer System must be
linked to the ECM: Refer to section 11
“Immobilizer System-ECM replacement” for the
ECM/Immobilizer linking procedure.
• Should Tech2 display "SPS Procedure was not successful", engine will not start, but no DTCs
are present, low battery voltage or poor electrical
connections should be the primary suspects.
Perform the SPS procedure again after rectifying
the fault/s. IMPORTANT:
Perform the following checks before attempting to
program the control unit:
• The Tech2 PCMCIA card is programmed with The latest software release.
• The latest release of TIS2000 is loaded 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.
• Tech-2 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 Data1. 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
6. If you select “continue”, you have to select “Model Year”, “Vehicle Type”.
7. After that. then 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 (A/T
only) 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 “System Type” for required control unit.
• Engine (Programming for ECM or PCM)
• Transmission (Programming for TCM)
4. When a lack of data is asked from among the following menu, enter accordingly.
Select following Menu
• Model Year
• Model
• Engine type
• Transmission type
• Destination code (vehicles for general export)*1
• Immobilizer
Etc.
* 1: How to read the destination code
Destination code can be read from ID Plate affixed on
vehicles, while on VIN 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"
(Australia).
