PLOTTING SNAPSHOT GRAPH
This test selects several necessary items from the data
list to plot graphs and makes data comparison on a long
term basis. It is an effective test particularly in emission
related evaluations.
06 0RX03 7For trouble diagnosis, you can collect graphic data
(snap shot) directly from the vehicle.
You can replay the snapshot data as needed. Therefore,
accurate diagnosis is possible, even though the vehicle
is not available.

Procedures for transferring and displaying Tech2
snapshot data by using TIS2000 [Snapshot Upload]
function is described below.
Snapshot data can be displayed with [Snapshot Upload]
function included in TIS2000.
1. Record the snapshot data, in Tech2.
2. Transfer the snapshot data to PC.By analyzing these data in various methods, trouble
conditions can be checked.
Snapshot data is displayed by ex ecuting the three steps
below shown:
After recording the snapshot in Tech2, transfer the data
from Tech2 to PC by the below procedures.
1. Start TIS2000.
2. Select [Snapshot Upload] on the TIS2000 start
screen.
3. Select [Upload from trouble diagnosis tool (transfer
from diagnosis tester)] or click the corresponding
icon of the tool bar.
4. Select Tech2, and transfer the recorded snapshot
information. 5. Select the transferred snapshot.
6. After ending transfer of the snapshot, data
parameter list is displayed on the screen.

corresponding icon of the tool bar.
4. Select the transferred snapshot.
5. Open the snapshot, to display the data parameter
list on the screen.
Graph display Values and graphs (Max. 3 graphs):
1. Click the icon for graph display. [Graph Parameter]
window opens.
2. Click the first graph icon of the window upper part,
and select one parameter from the list of the window
lower part. Selected parameter is displayed nest to
the graph icon. Graph division can be selected in
the field on the parameter right side.
3. Repeat the same procedures with the 2nd and 3rd
icons.
4. After selecting all parameters to be displayed (Max .
3 parameters), click [OK] button.
5. Parameter selected is displayed in graph form on
the right of the data parameter on the screen. 6. Graph display can be moved with the navigation
icon.
7. For displaying another parameter by graph, click the
parameter of the list, drug the mouse to the display
screen while pressing the mouse button and release
the mouse button. New parameter is displayed at
the position of the previous parameter. For
displaying the graph display screen in full size,
move the cursor upward on the screen. When the
cursor is changed to the magnifying glass form, click
the screen. Graph screen is displayed on the whole
screen.

Display of graphs on one screen (Max. 6 graphs):
1. Click the 6 graph icon. [Graph Parameter] window
opens.
2. Click the graph icon, select the parameter to be
displayed from the list and change divisions
according to necessity.
3. Repeat the same procedures with the graph icons,
from the 2nd to 6th.
4. Click the [OK] button to display.
5. In this case, parameters are displayed only in graph
form. All parameters are displayed in one graph.
6. The graph display screen can be moved with the
navigation icon.

SERVICE PROGRAMMING SYSTEM (SPS)
The procedure to program the control unit by using the
Service Programming System (SPS) software contained
in TIS2000 is ex plained 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 ex isting module or new
programming by the replaced/new module.
Fix ing position of the control unit.6. Upon completion of the selection, push the button of
“Nex t”.

ENGINE DRIVEABILITY AND EMISSIONS 6E–85
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 ex isting 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 “Ex it”
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 affix ed 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).
