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.
