How It Works
This is a “normally open (NO)” switch. When the parking
brake is engaged, the switch is closed and there is
continuity between the switch terminals.
Testing
1. Disconnect the switch from the wiring harness.
2. With a multimeter set to the “Ohms” setting or use
a continuity light. Verify that there is continuity
between the terminals (plunger in).
3. With the plunger out, there should be NO continuity
between the terminals.
