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).

5. After choosing the data, click the “Next” button.
6. 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.
7. “Data Transfer” comes on display. The progress of downloading will be displayed on the screen in the
form of bar graph.
8. Upon finishing the data transfer, turn off the power of Tech-2, removing from P/C. 4. Programming of ECM
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 “Fl: Program 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.

HOW TO USE BREAKER BOX
The engine control module (ECM) and other connectors
have water proof connector and special terminal. Water
proof terminal does not allow to use back prove. In
addition, the engine control module (ECM) special
terminal can not let regular digital voltage meter prove
to access, because terminal shape is very fin pin type.
In order to prevent damage of female terminal and
connector itself, the breaker box and adapter is the
most suitable special tool.

ON-BOARD DIAGNOSTIC (OBD) SYSTEM CHECK
Circuit Description
The on-board diagnostic system check is the starting
point for any driveability complaint diagnosis. Before
using this procedure, perform a careful visual/physical
check of the ECM and engine grounds for cleanliness
and tightness.
The on-board diagnostic system check is an organized
approach to identifying a problem created by an
electronic engine control system malfunction.
Diagnostic Aids
An intermittent may be caused by a poor connection,
rubbed-through wire insulation or a wire broken inside
the insulation. Check for poor connections or a
damaged harness. Inspect the ECM harness and
connector for improper mating, broken locks, improperly
formed or damaged terminals, poor terminal-to-wire
connection, and damaged harness.
Te s t D e s c r i p t i o n
Number(s) below refer the step number(s) on the
Diagnostic Chart:
1. The Check Engine Lamp (MIL) should be ON steady
with the ignition “On”, engine “Off”. If not, “No Check
Engine Lamp (MIL)” chart should be used to isolate the
malfunction.
2. Checks the Class 2 data circuit and ensures that the
ECM is able to transmit serial data.
3. This test ensures that the ECM is capable of
controlling the Check Engine Lamp (MIL) and the Check
Engine Lamp (MIL) driver circuit is not shorted to
ground circuit.
4. If the engine will not start, “Engine Cranks But Will
Not Run” chart should be used to diagnose the fault.
6. The Tech2 parameters which is not within the typical
range may help to isolate the area which is causing the
problem.
12. This vehicle is equipped with ECM which utilizes an
electrically erasable programmable read only memory
(EEPROM).
