You should be familiar with the tools listed under “Special Tools” in this section. You should be able to measure
voltage and resistance. You should be familiar with proper use of a scan tool such as the Tech-1 Diagnostic Com-
puter, Driver/Passenger Load Tool, Connector Test Adapter Kit and the Digital Multimeter.
Special Tool (Connector Test Adapter Kit)
(A): 09932-76010
This must be used whenever a diagnostic procedure requests
checking or probing a terminal.
Using the appropriate adapter in the special tool will ensure that no
damage to the terminal will occur from the multimeter probe, such
as spreading or bending.
The adapter will also give an idea of whether contact tension is suffi-
cient, helping to find an open or intermittent open due to poor termi-
nal contact.
