ITK-4 Test Kit Contents
ITK-4 Kit and its components
The ITK-4 Test Kit (figure #1) was designed to replace both the ITK-2 and ITK-3 test kits and can be
used on both Spectrum Series II and Series III systems. The ITK-4 Test Kit incorporates a new dongle
(ECOM Cable P/N E2046002) to connect your Diagnostic Scan Tool (DST) to a Series II or Series III
equipped vehicle. The ECOM Cable is equipped with a Spectrum III DLC connector for direct series III
connection. To connect the ECOM Cable to a series II vehicle DLC you will need to use the adapter
cable (E1557400) included in the kit (refer to chapter II for complete instructions). The ECOM Cable is
Controller Area Network (CAN) enabled for high-speed connection to CAN enabled systems.

PASSWORD LOGIN
Figure 1 shows the password dialog box, which is displayed when a software session begins.
Login can be accomplished in two ways.
1. Enter an “All S/N Password” which is a password applicable to all ECMs of a given original
equipment manufacturer (OEM).
2. Enter a “Single S/N Password” and corresponding ECM serial number for a single ECM. A
Single Serial Number password is unique to a specific ECM serial number and permits
authorized service personnel to make changes or view information for a specific ECM.
3. In most instances the top “all” serial number boxes should be used for password entry. In this
case, do not check the single serial number box. Each password is a 16-character alpha-
numeric string specific to each Spectrum customer and determines which pages and variables
are visible through the software. Passwords are assigned by the OEM support group and may
change periodically. Check the “save password” box to automatically retain the password for
future use.

PASSWORD DIALOG BOX FUNCTIONS
•Clear Password Button Erases the current password from the password field.
•Paste Password Button Allows the user to copy a 16-character string from any word
processor and paste the string in the password field.
•Single Serial Number Access Checkbox Tells the software that the password is applicable for
single serial number access.
•Serial Number Field Only applicable when Single Serial Number Access Checkbox is checked.
The entry field must be populated for the 6-digit serial number for which the Single Serial
Number Access password applies (NOTE: Leading zeros included in the serial number are not
required).
•Save Password and S/N Checkbox Retains the password, and serial number (if applicable) for
the next software session.
Should an invalid password be entered, the error prompt shown in figure (2) will be
displayed and the software will not load. This prompt signifies the following:
•The All S/N password is invalid.
•The Single S/N password is incorrect for the Single Serial Number entered.
•An All S/N password is entered for Single Serial Number use.
•The Single Serial Number password is valid; however, the Single Serial Number Access
Checkbox is not checked.

If the Single S/N password entered is correct for the software but does not match the entered S/N
of the targeted ECM, the prompt in Figure 3 will be displayed.
Figure 3: Incorrect Serial Number Message
Figure 4 shows the communication status if a valid software password is entered when attempting
to connect to an ECM with a different key. In this instance the software will load but will not
connect to the target (ECM).

In the event you receive this error message call your OEM support group for more information.
Connecting The PC To The Spectrum Fuel System

A laptop computer, with the diagnostic cable and software is the required tool for performing proper
diagnostic testing of the Spectrum fuel system. It is also used to monitor sensor and actuator
values and to read and clear Diagnostic Trouble codes. The DST software also performs several
special tests.
•Connect the system diagnostic cable to the RS232 port on the back of the computer. If you do
not have a RS232 port, use the USB to RS232 adapter supplied in the IMPCO ITK test kit. Be
sure to install the USB driver to enable the USB adapter for use with your computer.
•Connect the diagnostic cable to the DLC (diagnostic link connector) labeled in the electrical
schematic. The DLC is located on the engine harness. The new 8 pin DLC requires the use of
the 4 to 8 pin adapter included in the late model ITK test kits.
•Turn the computer ON.
•Start Windows.
•From the start menu select Programs→Impco GCP Display→Impco GCP Display
•Place the ignition key in the ON position.
Within several seconds the system Gauge screen should now appear and a green banner in the
upper left hand will read “Connected.”

•To connect using the ECOM cable you must select ECOM from the COM Port drop down menu.
•You will now need to configure the ECOM communication protocol.
•Select the CAN for systems with CAN enabled or serial for all others. Then select OK. You
are now ready to connect using the ECOM USB DLC cable.

Tool Usage Instructions
A. Fuel Pressure Gauge (TG-31119-001):
Refer to the fuel pressure gauge instruction booklet included in the ITK-4 Test Kit.
B. Differential Pressure Test Gauges (TG-005 & TG-010):
•Both the TG-005 (0-5 PSI) and the TG-010 (0-10” WC) are differential pressure gauges. This
means they can be used to measure the difference in pressures between two separate areas
or they can be used to measure either positive pressure or negative pressure (vacuum).
TG-005 TG-010
•Before using either of the differential pressure test gauges, they should to be calibrated against
a manometer or known calibrated gauge.
To calibrate a gauge:
Remove the front cover by unscrewing it in a counter-clockwise direction. You may need to
use a pair of channel lock style pliers (be careful as the cover is made of plastic). DO NOT use
any clamping tool on the body of the gauge.
