The best way to test the circuit is with a multi meter
Part number: AP5641751
And to test the circuit at the three(3) pin connector on the ERC/Clock. Unplug the connector, place one meter probe on/in the #1 wire and the other meter probe in/on the #3 wire, of the harness connector. You'll need to manually operate the switch on the latch mechanism. In the "relaxed" / unlocked position there should be an "open" circuit. When the switch lever is "actuated" / locked position there should be a "closed" circuit. Doing this test in this manner will verify if the switch, wiring and connections are proper.
