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.
060RX037
For 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.

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 poo
r
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.
Diagnostic 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 Data
1.
Connect Tech-2 to the vehicle. When activated b
y
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 Tech 2, 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). Fo
r
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

Etc.
* 1: How to read the destination code
"Destination code can be read from service ID Plate
affixed on vehicles, while on service ID plate the
destination code is described at the right-hand edge o
f
Body Type line. In the figure, the destination code can
be read as "RR3" (Australia).
