Using Connector Test Adapters
WARNING: This page is about a different car, the 2001 Chevrolet Monte Carlo and 2001 Chevrolet Impala. However, it is still accessible from the selected car via links, so may be relevant.
NOTE:
Do not
insert test equipment probes into any connector or fuse block terminal. The diameter of the test probes will deform most terminals. A deformed terminal can cause a poor connection, which can result in system failures. Always use the J 35616-A Connector Test Adapter Kit or the J 42675 Flat Wire Probe Adapter Kit in order to frontprobe terminals. Do not
use paper clips or other substitutes as they can damage terminals and cause incorrect measurements.
