GLOSSARY
How It Works
When the seat is vacated, the switch is open and there
is no continuity between the two terminals. When the
seat is occupied, the switch closes and there should be
continuity between the two terminals.
Testing
1. Disconnect the switch from the wiring harness.
2. With a multimeter, check the continuity between
the two terminals of the switch. There should be
NO continuity.
3. With weight or pressure on the seat, check the
continuity again on the two terminals of the switch.
There should be continuity.
